Computer not recognizing 2nd of the same WD mass storage device

Q: Computer not recognizing 2nd of the same WD mass storage device

I have two WD 3tb external drives. They both work but only one at a time. I am running Windows 7. I have renamed both drives but still no go. I have previously have had a 2tb and one the 3tb drives running at the same time with no problem. I had to upgrade to the 3tb from the 2tb because of the size of my projects I am working on. Does anyone have a solution?

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.)

When I connect my eFilm device to my computer (MS Vista), in order to transfer pictures from my digital camera to my computer, my computer does not recognize or acknowledge the eFilm device (USB).

How do I get my computer to recognize a mass storage device (G drive)?

Thank you for any help.

On my tool bar at the bottom of the screen there is a safely remove hardware icon. When I select it takes me to screen that gives me 2 selections to safely remove hardware. One is my printer and the other is USB mass storage device. When I highlight either it shows me the device name again and says at location 0.
" HP Photosmart 3100 series at location 0"
" USB mass storage device at location 0"

Why is the icon there to give me the option of removal? Should I remove? What is the term "mass storage device referring too?

Thank you

Your printer probably has a sdcard slot on it. You can remove the memory card from your camera and put the card directly into the printer and print pictures directly from it. No need to bother to remove it or shut it down.

When I put files [eg songs in this case] onto the USB device and then stick it in another computer it lets me play them but it says I can only do so while its plugged in. I got it because I was sure I would be able to copy them onto the second machine. It's not the write-protect switch that's preventing me...I've tried that approach.
I may be able to copy them with WMP by "copying the now playing" but that would be too slow.[if it even works]
Any help and suggestions appreciated.

I am having trouble with my IPOD I was wondering if this error was the reason it wasn't working?
This is what error message comes up for the mass storage device:

Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42)

Click Troubleshoot to start the troubleshooter for this device.

A:Mass Storage Device

I always reply to the head scratchers. Please un-plug/turn off all your USB devices EXCEPT the Ipod, your keyboard, and mouse. This includes your printer, and any Jump Drives you may have plugged in.

1.) Open your Device Manager
-Right click on my computer
-Select 'properties'
-Click the 'hardware' tab
-Press Device Manager

2.) Do you see your Ipod on the list? If so, uninstall your IPOD. I don't have an IPOD so i don't know what group it would be stored in, but I would assume your Universal Serial Bus Controllers.

3.) Download a new Ipod driver or load the Ipod driver off your cd like you did the first time you installed it.

I hope this fixes it.

Hi All,

Been using the new Windows 7 for a week or so now, everything is great! But i have one big issue. Every time i plug in a USB pen drive or my tomtom device, a window appears with a message saying that the device drivers can not be installed. When i click on the ballon message it just displays the device followed by a red X and 'Failed'

I have tried many usb mass storage devices and i still have the same issue.

Can anyone help???

Thank you for your time.


A:USB Mass Storage Device

Sounds like you have some issue involving "uppers filters" and USB ports and devices. Do any USB devices work well?

You could Google that and try to find an answer or how to edit the registry to repair it. I'd tell you but I forget where to look in the registry to do this.

In any case, if you attempt, set a restore point before.

Try a Windows Update while device(s) is/are attached. See if they need a drive letter assigned in disk management.

If not, pick your favorite one and right click on it in the device manager. Properties. Details tab. Change dropdown to hardware ids. Copy and paste results here. No screenshots as alternative, please.

I plugged in my external Hard Drive (Laptop Hard Drive in a USB cradle) and it worked fine - Opend it up and browsed some files. I then a day later plugged it in and it asked for drivers, It searched windows update but did not find any. I cannot not access the drive although it worked first time.

Any ideas?

Thanks, John.

hi, recently my creative zen has died. i believe the problem is the unit and not the 40gb fugitsu hard disk. i really need to recover my music as i am living in europe and my cd's are back in australia. i had 25gb of mp3's on there... i have just bought a hard drive housing and placed the hard disk from my mp3 player into that hoping i would be able to recover my files. my computer recognises the usb device, recognises the hard disk type and model no. , but says that it is not initilized. when looking at the properties of the drive it recognizes the size but not the partition style etc. im wondering if this is because my mp3 player has its own way of accessing the disk and windows xp doesnt recognise the format style??? i dont know much about this stuff and really would appreciate any help with it..


A:mass storage usb device


Yes I am guessing, but from what you are saying, it sounds like Creative has its own proprietary disk format?

Have you tried contacting them thru their Website?

Do you know anyone with a similar unit that would let you install the drive to off load the music files?

I have a Genesys usb mass storage unit. I have the Vista driver and it's been installed properly. The problem is that it doesn't show up as a drive under my "computer."

I have tried to update the driver, uninstall and re-install and it still won't show up. It does show up in the "safely remove hardware" window and the device manager.

Try these.... they are harmless steps...
1:stop plug and play service in services.msc and restart it... then,
2:start->right click on "computer"-> left click on manage-> on L.H.S. click on storage, click on disk management...on the R.HS. check in disk management if that USB drive shows up as unallocated space. If yes, reply to this post.

I recently lost my hard drive and had to rebuild from scratch. Everything works well with one exception. Whenever I plug my Olympus D520 camera into the USB hub (powered), windows says it sees new hardware and the promptly reboots. Upon the reboot, the camera is seen as a disk drive. Not liking how this worked, I then installed CAMEDIA 4.0 (Olympus Camera Product). Now when I plug in the camera, it still reboots but when the system gets nearly loaded it see's the camera as new hardware and reboots again. This will go on forever unless I unplug the camera, then the system boots nicely. Any ideas here?

Good day guys

The pc's at my local library keeps hiding all data on any mass storage devices connected to it and creating broken shortcuts off all data on the data on any mass storage device connected to it. Any other computer is then unable to view data on the mass storage device.

I can recover my data easily and I have put on a warning script on the library pc's to warn people of the problem. Locals using these pc's are in danger and I do fear someone would come in and try to use an external hard drive disk.

My question is: What is wrong with these pc's and how do I fix the problem?

According to the official specs ( ),your PC seems to have come with USB card reader. XP will show the "Safely remove Hardware" message if there is a card reader is plugged so there is nothing wrong with that.

ried the wizard a few times - Windows can’t find the software. I don’t have a disk that it will take either.

Hello, everyone =)

OK, well, I've got an external hard drive that I'm connecting to my USB port. I can mount it just fine in linux (mount /dev/sda1) but in Windows XP Pro, it appears in the system tray as a "USB Mass Storage Device" but I can't seem to access it from "My Computer" in any way. I'm a Linux user who is rather new to Windows, but I still have a feeling that this is not my own problem. Anyone have any ideas of what is going on?

Thanks in advance

A:Windows XP Pro not seeing a USB Mass Storage Device

You may not have a windows filesystem installed on the drive yet. If that's not the problem, try this fix:

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

You may want to move or copy all your files on the drive to your W2K machine, then plug it into the XP machine. You also might want to look for drivers for it, but XP should be able to detect it.

I recently purchased a new digital camera I brought it home connected it to my computer by USB and followed the instructions to upload the pictures to my PC I had some difficulty realizing that my computer actually recognized storage XP mass not detecting device it as a mass storage device but eventually it worked I was very happy Less than a week later I had some more pictures I wanted to upload I connected the camera to the computer and nothing happened The camera did not respond it essentually turns off while connected to my computer the E drive did not show on My Computer and when I opened up the software I use to upload the pictures no mass storage device was detected as being attached to my PC I didn't install any drivers for the camera so there really isn't anything to re-install It's like the computer is completely unable to realize anything is connected to it I've tried uninstalling reinstalling my USB root hubs editing registry keys http support microsoft com default en-us uninstalling the uploading software hey it was XP not detecting mass storage device worth a shot restarting my computer a million times plugging the camera into different ports I read that plugging something in to the ports on the back of my PC that are connected to the motherboard directly would do the trick--this just caused a power surge and froze my PC and performed an exorcism My Device Manager doesn't show anything at all as being connected to my computer The E drive doesn't show up Nothing I have a Wacom tablet that I plug in to my USB and it's working just fine After I uninstalled the USB root hubs I plugged it in and XP automatically detected it and installed it again But when I plugged in the camera it's like it isn't even there I'd appreciate any suggestions Thank you

A:XP not detecting mass storage device

The fact that your PC froze sounds like a bad cable. The only other logical solution is a bad camera port. Take it to a Drug store self service photo booth & see if it works there. Many give the option of inserting the memory card or the USB cable.

There is probably nothing wrong with your PC.

I have assembled a SOYO Dragon 2 v2 with 1 gig mem, SATA Western Digital HD, 2 IDE DVD/CD roms,. device manager shows 2 mass storage controllers under "Other Devices". the 2 Disk roms, and the SATA HD are listed correctly in device manager. My SOYO board has 4 IDE connectors and 4 SATA connectors, should I just delete the other devices and reboot the system or disable the other controllers in BIOS?

Thanks for any assistance

Plug the Flash Drive in if you get the Hardware Wizard, let it install. If you do not get the hardware wizard and the device is not listed in My Computer, then go to Start/Run and type devmgmt.msc and hit enter. In the Device Manager, expand Universal Serial Bus Controllers, if you have a Unknown Device, then right click it and uninstall it. Now pull the drive out and put it back in. Go through the hardware wizard if asks.

No drivers are required for USB mass storage for 2K/XP.

I believe your problem is probably that you haven't formatted the drive yet. Right click on MY Computer, Manage, Disk Management. You should see the new drive in the bottom section with all the space as Unallocated. Right click on it and Partition and Format it.

I have a problem where the card reader uses a mass storage device driver.

However after the MP3 players device driver is installed and the MP3 player is connected, the MP3 player only connects for a second and then disconnects again.

I belive the problem is caused by the cardreader and mp3 player trying to use the same device driver.
Has anybody else experienced this problem or know any potential fixes to this problem.

I can't think of a solution off the top of my head, so this will be trial-and-error.

Then you want to remove the drive. You click Safely Remove Hardware, and then it gives the error?

A:unable to open mass storage device

sounds like it its corrupted. Not much windows will be able to do if it wont let you open it that is about it from that side. Something I would try is seeing if it will open under a linux partition. If you go to Download - Linux Mint you can download it to a bootable CD and then run it with out installing it. It is worth a shot to see if it will open it. If it does open it just copy it to another drive and then reformat that one. The only other option that i know of is to send it to a professional data retrieval person. VERY expensive so guess it depends on what the data is worth to you.

Also, USB 3 write speed was extremely slow - it often took more then 8min to write a 5GB file into the drive. During the writing process, the writing speed cycled between 0MB/s to 90MB/s. Most of the time, the writing speed stayed at very low values, < 1MB/s.

Device Manager reported that I have the latest UASPStor driver. If I disabled the UASPStor driver, the drive became disconnected.

If I plugged in the Seagate drive into a Win 7 machine, it worked perfectly well.

Can anyone help me to solve the problem?

I recently added a Maxtor 80 gig external hard drive mainly as a storage device and it has malfunctioned. It wont come on except for a brief second when windows tells me it has no drivers then it goes off and windows says the device isnt connected. Have I now lost everything on this device? Is it the wiring? Is there anything I can do to retrieve whats on this drive?
Thanks in advance for any advice.

Recently I've bought a new pc and somehow the system cant detect my external CD rom burner drive when i connect it to the USB port. I did a check on the status of the USBC Mass Storage Device from the device manager and it says "This device cannot start. (Code 10)". The troubleshooter help doesn't seem much too useful.

i've had no problem with the USB with my previous computer. Really can't figure out what's wrong. Any kind souls there who can offer me some advice? Really appreciate it. Thanks many much!

After attempting to 'Eject' my flash drive (all programs closed), I got this message. I've just transferred lots of data over to it using Synctoy, and do not want to risk pulling it and potentially damaging what's on there. In the past I've pulled these drives regardless of message, but ended up with various empty (0-1KB) picture files strewn everywhere.

The drive is still plugged in, I want to learn how to remove this flash drive safely. Can someone help?

A:Problem Ejecting USB Mass Storage Device

The simplest way: Restart Windows.
In closing down Windows will force an end to the writing process and "safely remove" the drive before shutting down to restart.

With it plugged in go to the Control Panel>Administrative Tool>Computer Management. Double-click on Storage. Double-click on disk Management.
On the top, click on Action and select Refresh

If it doesn't show, go to your Device Manager and see if there are any yellow exclamation points by the USB Root Hub Controllers

I have many USB driven devices, flash drives, MP3 players, etc. and when i transfer data to these devices, the data becomes corrupt and unusable, or in music/pictures, the data only seems to get partially there. After transferring some images to the mass storage device, they came out garbled, like the pixels were rearranged and put in the wrong order. Some images are not even viewable. Music skips, as if I was playing a CD with deep scratches.

Transferring data from these devices have no effect on the data, it only occurs when I am sending it to the device. I have used every USB port on my computer with no success. One bizarre occurrence I have noticed is that I have a USB printer that seems to be unaffected by this corruption.

A:USB Mass Storage Device Data Corruption

How many USB devices do you have and how many ports. Are you using hubs?

External devices are slow compared to hard drives. If you are experiencing corruption playing music and video files from USB, they may be too slow. Copy the files to your hard drive.

USB has limited bandwidth, like anything. Too much data cannot be transferred at one time.

A:Missing Mass Storage Device Driver

Sounds odd to me, but the first place I would start would be to download the chipset drivers for your computer, unzip them into a folder, and when asked where the driver is, point it to that folder...

Windows 7 will search through all the subfolders thoroughly for a driver... Hopefully it's in there...

If not, go to device manager, select the device that doesn't have the driver (mass storage...) and double click, or right click and select properties.....

Go to the details tab, and under hardware id's or under parent, look for the vendor & device ID's and copy them exactly for us to see what the device is...

It'll look something like this: PCI\VEN_8086&DEV_3A39&SUBSYS_3A398086&REV_00\3&2411e6fe&2&D2

A:Missing USB Mass Storage Device driver

Hello Clueless96, welcome to the forum

Try this, take your time and work through it line for line, it is not as hard as you may first think;
General USB problems
After a USB device is installed and then removed Windows hides the driver this first part makes all hidden drivers visible.
Remove all USB devices
Click on start orb, Type Advanced System settings in the search box and click to go there.
Click on Advanced tab, Click on Enviroment Variables.
Under the window System variables click on New.
Type " devmgr_show_nonpresent_devices" (without the ") as the variable name and type 1 as the value.
Click ok 3 times to close the windows
Click on start orb, Type Device Manager in the search box and click to go there.
Click on View, Click on Show hidden devices.
Now you can uninstall all old and unknown USB devices. I think it will be best if you uninstall all USB devices
The infcache.1 file is used to store information about USB drivers, the information in this file may have become corrupted or may cause windows to load the wrong driver or cause a driver not found message to be generated.
Deleting this file will force windows to generate a new infcache.1 file
Right click on the start orb and select Windows Explorer,
Select Computer in the address bar and search for infcache.1
Right click on the file infcache.1 (if you have more instances of Windows installed only do this for infcache.1 C:\Windows\System32\Driver Store)
Click on properties, Click on security tab, Click on Edit, Click on Add
Type Administrators In the window with the blinking cursor, Click OK
Place a tick in the box under allow to the right of Full Control, Click Apply, Yes and OK
Delete the infcache.1 file
Connect a USB device, but not the one you were having trouble with to make a new infcache .1
New Start the PC and try your device again.

More from the "I Hate Vista" department:

I'm posting this in the Vista forum because I don't remember ever having this problem, especially to this extent, when running XP or 2000.

Vista simply will not let go of my USB flash drives most of the time. I have to either log off or shut down the computer to remove it. It doesn't matter if I wait five minutes or fifty minutes; the result is the same.

I open Task Manager and shut down all running programs, I go through the disconnect procedure repeatedly and Vista just will not let go.

Is there a fix for this; it's really getting aggravating?

I have several mass storage devices (SanDisk thumb drives, and a Seagate FreeAgent Go external hard drive). All have functioned properly on my Sony VAIO laptop for a long time. Suddenly, none of them are recognized by my computer. I have tried to uninstall and update the drivers in the Device Manager. The update/install is successfull for all the USB connection drivers, EXCEPT for the USB Mass Storage Device driver, which continues to have a yellow exclamation point on the icon. How can I fix this driver and get my USB devices recognized so I can use my data? Thank you!

I have an external mass storage device containing a 60 gig hard drive.

This "caddy" by Belkin has an ON/OFF switch as well as the usual USB connection.

If I reboot the PC with the unit ON, the whole thing freezes and won't start up.

If the unit is OFF during the reboot, everything works fine.

Likewise, after the reboot, turning the unit ON gets it working and there are no problems.

I guess something in the BIOS BOOT section has to be fiddled with to fix this?

A:Won'r boot when external mass storage device is connected

Yes it could be that your bios has usb drives enabled for booting.

A:Mass Storage Controller Error in Device Manager

You will have to find out what the device actually is and get the correct driver for it. Does this computer have a driver disk with the system? If so the driver will be on the disk. The only other way is to go to the computer Manufacturer's web site and locate the driver download section and get the driver there.

Hey all,

I just bought a second hand U200-104 and am installing it now. My OS is Windows Vista Business 64bit & the 32bit seem to be working ok. Though i installed all there is to it on the driver page i keep having an unidentified "Mass Storage Device" in my device list.

In the properties, it says:
- Location: PCI-bus 3, Device 11, function 2

Hope someone can help me !
Thanks a mollion in advance :)

Hi buddy,

To be honest this information is not useful?
You should check the device and vendor ID in device manager of this device.

At the moment it?s hard to say what device it is but you should try installing the card reader driver. Check the Toshiba website for this!!!

I have an Acer R3610 (so everything is via USB). When I plug in an I/O Magic disk drive, I get an error "Device driver software was not successfully installed".

I had earlier tried to fix this situation by going to Device Manager and deleting all drivers under USB controllers. When I rebooted everything re-installed except for USB Mass Storage Device.

So I need some new ideas.

Rather implausibly I used their site search to look for an I/OMagic drive, hoping to get a listing for drivers, they have no results for it !
But depending on the model number you might try here to get an updated driver version. I/O Magic Drivers - I/O Magic Windows Drivers
