Q: External Expansion Drive with own power supply

Can anybody Help Me !!

I have set up a Server type machine on a HP Touchsmart running Vista

I have purchased a Seagate 2TB Expansion Drive with its own power source

I desperately want to know how this external drive can be seen by other devices on the network

I have other external drives with their own power supply and non of them can be accessed by other computers on the network....Is there a trick to these devices!!!

I have external hard drives with NO power supply just USB connection and I can access them from any computer on the network and any media device on the network

I'm not very technical and would like to know if its just the type of device and I should be buying usb connected hard drives for music and movies

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

You need a router that has a USB connection. Then you can connect the external storage to the network. That is only for a USB drive though. Do you have one of those passport drives with a battery?

My Sister inherited a used Panasonic Toughbook with an external CD Drive. However the donor did not include the power supply adapter for the drive. She wishes to replace it and need my advice on the volatage that it uses. The kicker here is that there is no brand name on the drive.

At the bottom of the unit where the warning Notes are, there is a
"Read the User manual notation with an open book logo with an "I" on the right page of the book" I'm right in assuming it be an Iomega Product.

I need to know what voltage to set any adpter I might use, after all I don't want to fry the thing. Please help !!!!

A:Power Supply Voltage for External CD Drive

12 Volts would be a good guess .. but finding one with the correct connector/polarity might be tricky.

Might be just as cheap to replace the whole ODD external or a new enclosure.

I have looked around and around. I'm completely stumped.

I have a Lite-On external dvd combo burner. On the rear of the drive is the power connection, usb2.0 and l/r audio rca out jacks (red/white). Above where you connect the power cord is also a toggle on/off switch. During a move, this toggle snapped off. In the off position. I got to the card and the toggle switch is soldered to the card. No way to get in there (easily at least).

I haven't been able to find a replacement card and I'm reluctant to jam a paperclip (or whatever) in there wiggling it around and scratching up the card.

Any suggestions?

I have a 3.5" external hard drive that requires a (round) 5-pin power supply adapter. I lost the original, and bought a new one from an electronics manufacturer. The plug fits the slot, but I am not getting power to the drive and no signal is reaching the PC.

Without buying another power supply (the one I bought was hard to find - I had to go online and find a parts supplier, and I don't want to return it until I know what the problem is), how do I check to confirm whether the external drive is working, or that the external power supply and the drive are properly connected?

A:checking external hard drive power supply

IMO it would be much easier to just buy another enclosure and pull your drive out of the one you are using now. Install it in the new enclosure; good to go.

I have an Intel D946GZIS mother board ,Core 2 duo-1.86 GHZ processor.,400 W power suply,SATA Seagate-160 GB.

The external HDD is Seagate Barracuda-160 GB IDE.

Off late Ive been getting errors stating that there is a power surge on USB when I connect the external IDE HDD and all the USB slots are dead until the PC is restarted inspite of my HDD having an external power source.Why does this happen?

When I disable 2.0 in BIOS there is no such problem.But the USB connection is very slow.What could be the cause of the problem.What is the solution?

A:External IDE drive with power supply connected via USB 2.0 freezes PC .why?

If the External is faulty you could wind up with probs with the system itself. I would stop trying to force something into a system that may well have a current problem and see if I couldn't test it after I purchased a new usb wire for the thing at the very least.
Your External could very well be bad. Jazz

Ok, something weird is going wrong with a seagate drive I bought for my girlfriend. Its working perfectly fine on my computer, and it did initially show up on her laptop too. However, her laptop froze up completely and it had to be shut down via the button while it was plugged into the laptop. Now it doesnt turn up in My Computer, but only on her computer. Its present under devices, but nowhere else. Any help would be greatly appreciated and Id be happy to give any more details anyone might need to help me out. Thanks in advance.

Try right clicking on computer in the start menu, and select manage. In the window that opens after giving admin approval, selece disk management in the left column. It should show every hard drive connected to your computer. In the lower portion of the window, look for your Seagate, right click it and select change drive letter or path, in the next window click add and choosed a drive letter. Click OK. after the drive letter is assigned, you will be able to see the drive in explorer.

Hi, I am new to these forums. Was hoping to get some advice on using another power supply for a new vid card that i got. The vid card recommends that I have a 350 watt power supply, but mine is only 200. I do have another power supply from an older computer just laying around, but that is also only 200. Is there a way to use that also? Even if it does sit on the outside of my cpu it doesnt matter. I dont have a really fast comp, old P3 400, so my budget is very tight. (thus reusing existing parts) Any help is appreciated. THX

A:external power supply for v-card

What Video Card are you talking about? It may be a bit much for that system, you might want to get something a little more matched to the system.

There is a way to do this but it is a little different than you are talking about. The best way would be to use the other PSU to power things like Drives and fans. Those devices can use the connectors already on the PSU. This may work if you can divert enough power to the second PSU so there is enough power left for the other devices and the Video card.

This could be very easy to do, or it could be very difficult. According to your level of electronics experience as well as the particular PSUs you have. Some PSUs will only power on if the mobo connector is attached(which can be circumvented)

You'll also need a way to turn both PSUs on at the same time which is not too difficult either.

So I recently bought an Nvidia 9800 Gx2, and it turns out I need a 6-pin AND an 8-pin power connector thing for it. I don't have an 8-pin.

So I'm going to buy an external power supply. Any recommendations on which one I should get? It needs to have a 6-pin and an 8-pin connector.

A:External Hard Drives without their own Power Supply are not detected.

This is a rather common, but sporadic, problem. The issue, I believe, is that the USB ports on the problem PC are not putting out the specified power to run the drive. This is a problem typically seen in laptops.

IIRC, USB 2.0 specifications require the supply of 2.5 watts of power over a maximum of 5 meters at 5 volts (0.5 Amps). If you are ambitious you could test for the correct specs with a good multimeter.

The other possibility is that the problem external drive is requiring more power than is supplied by the USB specifications. This is not likely in your case because the drive works on other PCs.

One work-around, in either case, would be to used a powered USB port for that PC.

I have a Toshiba Satellite and when I plug in the external power supply the computer freezes and I have to do a hard shut down. This has also happened when I unplug the power supply, thought not as often.

Curiously if I keep the mouse moving when I unplug it does not freeze. I've tried keeping the mouse moving when I plug in the power supply and sometimes it works but most of the time it does not.

Any help with this would be greatly appreciated.

I have a Gateway GT 5082 ( Athlon 64 X2 , 2ghz flavor) I believe I have 2 problems if I want to purchase a decent video card. The stock power supply i believe is only 300W. Probably need around 400W to power a good video Card.

It comes with a PCI Express slot but even if I had the recommended power supply I really dont see an empty slot on the motherboard to put in the power connection from a new video card ( such as the nVidia 7950 GT ).

Do they sell external power supplies that I could run indepently of my computer and just power a video card? It would seem like a pain in the *** to replace the oem power supply so let me know what you think!

Yes I know there is an inherently 3rd problem the fact that I purchased a gateway haha... but just looking for some solutions here.

A:Hard drive or power supply?

I'd put money on a software problem. Is there anything specific that causes the lockups? Like opening a browser or running a game? Without a specific trigger for an error it's harder to troubleshoot. Two things you can try: first is safe mode. This will load generic drivers so you might quickly identify if it's software or hardware. Use your error trigger if you've got one. Once you've done that, you can move on. Second is identifying the offending driver or component. For software, you must uninstall drivers one at a time. I'd start with simple stuff like mice and sound. Reboot after each uninstall, and again, use the trigger. For hardware you've got to physically remove things one at a time. Same deal, reboot after each, until you've defined the problem.

One more thing, have a look at the event viewer. right click my computer, select manage, and it should be there.

Do I need to completely unscrew the power supply and all will become obvious?

I'm a little reluctant about doing that as it has a sticker on saying do not open, non servicable parts inside!

I am trying to buy some large hard drives for older Dell systems (ie) Optiplex GX110, etc. I continue to be told by the sales folks at BestBuy and CompUSA that there may be a power supply issue with the legacy systems.

Can anyone spread some light on this?


A:hard drive size and power supply

I doubt the difference between a new 7200 and old 5400 RPM hard drive is more then a few watts. The size, or capacity, of the drive has no impact as far as I know. If you are replacing an existing drive with a new drive then there will be no issue power wise. Even if you add a second drive I doubt you'll have a problem. I worked on many Optiplex systems and never had a problem adding a second drive or replacing the existing drive.

Now replacing a power supply in a Optiplex is hard er as most will not acommodate a standard ATX power supply.

One issue you may run into though is a BIOS limitation on the size of hard drive you can install. There are 8GB, 32GB, 127GB barriers. However DELL has BIOS for the GX110 that'll adds 48 bit LBA support which allows to use drives larger then 127GB if you wish.

My dad said he came home the other day and smelled something "electrical" burning and traced it to the computer, so he unplugged it.

I plugged it in to test it, and got a loud horrible sounding beep (so loud i'm not sure if it came from speakers or the hardware??) and then nothing happens Won't boot up. I just hear a vibrating/sickly humming sound in the box that is in the back of the case, with a fan, and as far as I can tell the fan is still spinning, so the noise most likely isn't the fan. Would this 'box' be the power supply? I am guessing so since this is where the power plug goes in at. Also, if it is indeed the power supply, would this problem inflict damage on other components?

Hey guys.

My Pc is a HP dc7100 Series. The workstation didn't come with a floppy drive installed, so i took it upon myself to install one.

Anyways i plugged in an OLD floppy drive, connected the ribbon cable and connected the power to the floppy.

And tried to boot..... The LED lights flicker, and the CPU and power supply fans run for about 2 seconds, then everything shuts down. After disconnecting the floppy totally the same thing happens.

I swapped out the power supply, and got my system running again.. I tried the "faulty" power supply on another pc and it gives the same results..

Question is how did i manage to kill the power supply? It shouldn't have been from installing the floppy...

Anyways, comments/ideas are welcome..

Just curious as to what the hell i did to cause this.. :blackeye:

I have Satellite Pro M500 with Windows 7 installed.

Detect correctly many USB pen drive (led inside ON) but when use "remove secure device" (right bottom) the led remain ON (never switch OFF). This for every model Keystone I have (2, 4, 8GB).

Last old XP based notebook switch OFF correctly power supply. Why this Toshiba not switch OFF right mode the pen drive?

Anticipated Thanks,

Do you really think that this is an issue?
To be honest sometimes I can notice the same that disconnecting a USB pen drive the LED doesn?t go off but Windows tells me I can remove the drive. So I think if Windows tells me that all should be ok.
What do you think?

Furthermore it would be interesting to know if you are running factory settings or your own Windows installation.
Make also sure that BIOS version is the newest.

Need help with this one. I shut down a computer one night, and the next day I noticed the hard drive light flashing. After examining it I could not turn it off holding the power button in, and it would not boot. Also noticed that the power supply is running. Held button in, and unplugged it, and plug it back in and can boot, but when I shut down, the same thing happens. Have not seen this one before., anyone have any ideas. Not my main computer, just one I set up for my grandkids.

A:HELP! My external hard drive has no power!!!

It might just be the power adapter or the enclosure that has died. You might be able to remove the hard drive from the enclosure and either install it internally in a computer or put it into a new enclosure. Most computer places sell enclosures if you need it in a hurry. Hopefully its not the hard drive inside the enclosure that has failed, in which case you hopefully have the all-important backups of your data.

I gave my external hard drive to a friend but his laptop didn't recognize it. after getting it back, I connected it to my laptop but it didn't show up in disk management at all. the drive is receiving power since the light is on. I felt the drive upon connecting to laptop and noticed it tries multiple times to rotate the magnetic disk but in the end it come to a stop and nothing after that. I think my friend's laptop somehow damaged my drive since I'm sure it's a hardware problem.
So, I was wondering maybe any of you guys have an idea how to fix it if possible otherwise, I'd like to know if I can recover the data without spending for the experts?

Got a Lenovo PC with Windows 7, when I tried to plug in my Hitachi external hard drive, it killed power to the PC immediately. I unplugged the HD, and power immediately came back on. This happens with any USB port, front or back. Tried switching cables, same result. The hard drive has an external power source, so it shouldn't be drawing too much power from the PC.

To make matters worse, after playing around with different ports, the mouse no longer works. When I plug it in, the light on the bottom flashes briefly, and that's it. I tried a different mouse. This time the light stays on but it still doesn't work. Did a system restore, no luck. Any thoughts, anybody? I'll be honest, I got nothin' on this one.

A:External hard drive kills power, also mice

Hi facetaco and Welcome to TSF,

I'm going on a wild guess that the external harddrive is Bus-powered? (No extra power adapter)

If you plug a harddrive in that doesn't have an external power source, the power unit of your laptop might not have enough power to keep all hardware running. This is most likely the cause of the issue. One other possible reason is faulty USB ports;

Can you plug other USB medias into the PC without it shutting down, like USB sticks?

All I get is a sound like a single "KERPLONK" when I power it on.

Wait, when you say you "removed it" where did you remove it from? From Safely Remove Hardware or from Device Manager?

Almost certainly the problem is that the current rating is wrong, if the laptop needs

Unfortunately it must be the right current rating, I know, I've been caught that way too!

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

gfx: Sapphire HD3850 512MB Ultimate (passive)

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you

Relevancy 53.75% we finally got my girlfriends new PC up and running. The problem im having...or more of a concern really. Is when you flip off the power supply, and then flip it back on, the PC gets a short burst of power. IE the lights and fans all come on for a second or two. Then you can press the power button and turn it back on.

Any ideas guys?

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

Hi, I have a Seagate USB3 500GB Portable Expansion Drive to accommodate my Back-ups and also any files I wish to 'transport' to another PC. I would prefer to leave the device connected to my PC except when I need to transport files. Will leaving it connected do any harm; should it be removed when not in use?
The PC it is connected to is NOT permanently switched on; being 'live' only for a few hours each day when in use.
Thank you.

A:Portable Expansion Drive.

I leave an external hard drive connected all the time. To me it's no different than leaving a mouse or keyboard or printer always connected. In fact, I have an older computer running Windows XP. The external hard drive on that machine has been connected for about 6 years with no problems.

I have a 3g usb seagate expansion drive that is about 3 mths old. It has frequently disappeared from my computer. I would have to reboot and disconnect the power from the drive to get it to come back.

Is this a sign of a bad drive or just a glitch that some kind of a driver update will solve.

In the same system I have a 6g WD drive that works flawless.

I bought a Seagate Expansion 5TB USB 3.0 3.5" Desktop External Hard Drive.
Not that it's really relevant to explain that other than to illustrate how important it is that I don't blow the thing up, but I bought it to create a disk image in Macrium Reflect Home Edition v6 (which I did), in preparation for upgrading from Win7 to Win10, just in case things go very badly when I do that.
But I notice that when it's plugged in and I right-click on it in Windows Explorer, no "Eject" option appears in the drop-down menu.
So I just unplugged it.
Is "Eject" just not appearing because an expansion drive is made in such a way that no preparation is needed before safely unplugging it?
Or am I risking data loss or worse by unplugging it without preparation?

A:Don't need to eject an expansion drive?

Down in your tray near the clock should be a "Safely Remove Hardware" button, clicking it should give a list of items you want to unplug from your system. Once hit to unplug/disconnect an item, the notice of "It is now safe to unplug {nameofitem} from your computer" will appear allowing you to safely unplug the drive

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

A:extra power leads on power supply?

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)
Without knowing the specs. on your motherboard this question is impossible to answer...Post Mobo identification (make/model) or obtain FCC ID and post that. Perhaps we can find a more definitive answer for you...BOL

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?

You're greatly risking the health of your whole computer while running with such underpowered power supply. Do yourself a favour and get a quality PSU. That's the cheapest one that is enough and of good quality that I could find with a quickish search.

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Case construction and drive cages are not the issue here.
