USB mass storage device not being recognized?

Q: USB mass storage device not being recognized?

I have WD 1 TB drive that was working fine. I noticed it had 3 partitions on it so I removed 2 of them with AOMEI Partition Assistant.
Aomei competed the operations and now my box will not recognize the drive. I tried it on my desktop and it also will not recognize the drive.
When I connect the drive, on either machine, it makes that "beep/bump" sound that lets me know something has been inserted but that is it.

Any ideas.

I went into device manager and told it to scan for hardware changes, that did nothing.
I tried to update drivers but that never completed. The progress bar just kept looking and did not find anything.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


Hi all, well this is a long shot now to post a question about my prety old mp3 player(Rio Chiba 128). The thing is that I have a good amount of good music I would like to copy off of it. Anyways I have Vista Home Premium 32bit and when I plug in the mp3 player, it recognizes it as being a Rio Chiba device but can not find any available drivers for it. I already tried the following:-changed the cable-directed the "New Device" wizard to look for drivers in C:\Windows\INF , C:\Windows\winsxs-copied different copies of "usbstor.inf" & "usbstor.PNF" into C:\Windows\INF and different locations but none of those have worked-I have even tried deleting INFCACHE.1 and nothing. -went to: http://www.digitalnetworksna.com/support/r....asp?prodID=109 which is Rio's support page for this device but they claim it doesnt need a driver as the OS should read it as a mass storage device.The mp3 player still works fine and plays music as it should it just doesnt want to be recognized in either vista or xp. any help or suggestions is really appreciate it as Im very little away from giving up on it. Thanks all!

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

Hi there,
Could someone please tell me why is the HL-DT-ST CDRW/DVD GCC4244 drive on a Dell Latitude D500 being recognized by the system as a usb mass storage device?...and how to fix that in case it is not normal?
Thanks in advance,

Disconnect the drive and tell us what the computer then reports. Your HLDS optical drive is among the most basic of all drives installed by Dell, but it has an extremely high failure rate.

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.

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?

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"

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.

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.

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.

Where can i download a usb mass storage device/driver or how can i get it back on my pc? I believe i deleted it because i remember removing it from add/remove programs and now i can't see it in device manager.

Before and after i deleted it my Iomega External USB CDRW Drive has suddenly not been detected by my computer(was not detected even when i had the usb mass storage device so this is not why it's not being detected). While i was removing other programs that i thought might have been causing this i accidently deleted USB Mass Storage Device from Add/Remove programs and i believe that is a driver i need for my usb plugs to work. As far as the cdrw drive goes i have tried everything on the Iomega troubleshooting page except for one thing that involves the usb mass storage device but now i don't seem to have it on my computer and i was wondering if there was somewhere i could download it or how i would get it back.

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?

May I know who can help me to understand what is the meaning/function of
Location information and
Address under the USB Mass Storage Device Properties?

What is the relation between the port# and Address#? Why some of the USB port number is same as Address number, but some of port is not?

Notice that some of the motherboard USB port# number and hub# number is not a static number when reset the eUSB drive to boot into ROM mode. Some of the port# number will changed, but hub# number remain static; Some of the hub# number will changed,
but port# number will changed.
For example, the motherboard Gigabyte GA-Z87X-UD3H have separately
Renesas® uPD720210 usb controller. Those USB ports under
Renesas® uPD720210 have same port number with address value. Those USB port under original chipset controller might have difference port number value from address value.

For those USB port under original chipset controller, the port# number will changed, but hub# number remain static when reset the eUSB drive to boot into ROM mode.
For those USB port under  Renesas® uPD720210 usb controller, the hub# number will changed, but port# number remain static when reset the eUSB drive to boot into ROM mode.

Hey All,

On my new build (Foxconn G31MXP-K; 4 GB RAM, Pentium Dual Core 2.5GHz) USB drives cause issues.

I've tried three different flash drives and a portable hard drive and have gotten the same result with all of them on both Windows XP and Windows 2000.

When I plug the drives in, they take a very long time to install, then appear to install successfully. On Windows XP, trying to access the drive after it installs would result in explorer locking up. In 2000, it results in an error saying "the disk is not formatted, format now" then when I accept to format the disk: "The disk cannot be formatted"

FWIW, I had started with JohnWill's USB repair technique (registry edit, removing all usb controllers, drives, etc, and reboot twice) but it had no affect on 2000 or XP's situation.

I have absolutely no idea what the issue is. I've got all the chipset drivers installed, and it just won't cooperate. USB is fine with the keyboard and mouse, but it seems as though everything else fails miserably.

Any ideas at all will be appreciated.

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.

Went to Device Manager, noticed USB controllers was opened and the USB mass storage device was highlighted. Went in the properties, this message was waiting for me, Code 47, Windows cannot use this device because it has been prepared for safe removal, but has not been removed? (There is no device installed in any of the ports etc.) To fix the problem, unplug device from computer(What device) and plug it in again.? All drivers are up to date as I checked them just now. The driver is from the 2006 year and when asked if I wanted windows to check, did so and found no new drivers. Kasperski has a driver on it more updated but since it is not signed I guess it won't install it. Did everything to try and install Kasperski's driver but to no avail. Also did the check for solutions but got no where, on line or off. Anyway, do use a 2 g storage device but always use the uninstall mass storage device when removing. Not a problem cause it does work with the device, just wondering if you can uninstall it and reinstall the driver under driver details or the uninstall as soon as you click on the USB mass storage device. Is this actually on the computer or is it the mass storage device I plug into the usb port?

My laptop, win xp ( Professional) sp3, of late has a problem.

Whenever I insert a new device such as a card reader, into the usb port, after it is

detected, and the software (usb mass storage device) starts loading the driver, I then

received the following error message:

'The software you are installing for this hardware: USB Mass Storage Device has not passed Windows Logo to verify its compatibility with windows XP. Continue your installation of this software may impair or destabilize the correct operation of your system either immediately or in the future. Microsoft strongly recommends that you stop this installation now and contact the hardware vendor for software that has passed Windows Logo testing.'

Two options are then presented:

Continue Anyway or Stop installation
If I choose continue, the device will have a Yellow and ? Mark as an unknown device on the Device Manager.

I do not have any problem with this card reader on my other win xp sp3 computers, and I have used the same card reader with this computer for years without any problem.

Any advice would be appreciated.

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.

Hello, searching around Google this forum has come up a few times now with threads about "USB Mass Storage Device" but I don't see a "solution".

If I can quickly outline my problem and then if anyone needs full specs ask away and I'll provide.

I've got a new PC. It has Vista Business x64 on it. All works fine. Or so I thought. Using the USB slots at the front of the machine for things like card readers or headphones they do their job.

When I went to plug a memory stick into the computer I got an error about "USB Mass Storage Device" failing to install. I tried other sticks. Same problem. I then tried some Maxtor external drives. Same problem each time. My iPod Video also hit the same thing. A Lightscribe external DVD writer... same thing.

Ok, maybe it is a device driver... so I uninstalled the device under Device Manager and scanned for new hardware... same problem. I deleted the USB controller - same problem.

I tried plugging each of these devices into the back of the computer in another USB slot. They all worked faultlessly (indeed the lightscribe is working away as I type this).

So the USB device driver seems to work - just not on that controller.

I found one thread that referenced C:\Windows\System32\DriverStore\FileRepository and looking to see if there are multiple entries like usbstor.inf_84963b7b (and others with different alphanum entries). There are.

I have tried to point the driver install at different ones with no luck.

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 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;314634), uninstalling the uploading software (hey, it was 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.

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.

Can someone please help me.....

I have data on several USB Hard Disks that I have used as backups. When I plug these into a new machine with Vista Ultimate 64 bit, Windows is not able to find the drivers for this.

These are not new-fangled devices - they are even recognised in Win98.... (many years ago!)

Windows is not able to find the drivers even looking on the internet.

Please help!

I'm using one of those pen drives(lexar 64mb jump drive) that plugs into a u
sb port. Only the other day, after my computer crashed, the device now fails
to work. It appears in device manager but says that 'the device cannot star
t(code10)' and i can't access it in explorer. I've tried it on a pc with win
98SE and xp and neither works.

And yes, i've tried re-installing the drivers (thanks lexar tech support for
that sage advice). Has anyone else had problems like this? It was work fine
before now and other than the PC crashing i can't think what could have hap

any ideas?


ps all i really want is the data off the thing! (i know i should have backed it up :-( )

A:usb mass storage device problem

Read other 10 answers

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.

I have an Easydisk 512MB USB flash drive which functions on my W2K PC at work (and several other PCs) but not on my Windows XP PC at home.

When I plug the device into the home PC I get a notification that new hardware has been detected and after a while (about a minute - which is obviously too long) the device gets a drive letter assigned (in this case F).

However, when I click on the F drive icon, I get the message "Please insert a disk into drive F".

My home PC has all the critical updates and SP2.

I have a feeling the device may be USB 1.1 - but surely this should still function?

I tried another approach and connected the USB flash drive when the PC was switched off. I booted the PC and once logged in it detected new hardware, it also stated that it was a USB 2.0 device (though I am not so sure). Once it was installed it asked me to reboot (which is odd). I did this and when I clicked on the F drive icon after reboot it still came up with the same error message as above.

There are no errors in device manager.....

Any help would be greatly appreciated as this is driving me nuts!!

Thank you


A:USB mass storage device not functioning

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 have a SanDisk 256MB and it works fine on XP)

Ok something very weird is going on here guys... I plug in a new portable Hardrive I got and a new video camera I got... it reads the USB but doesnt show up in my computer... in device manager it shows up but with a yellow question mark. These products are plug and play... dont need a cd to use em. I go to my laptop everything works fine... I take my thumbdrive plug her in works fine, take my other portable camera works fine. For some reason its not letting anything new be hooked up??? any reason why...? To me it doesnt make sense and ive pretty much tried everything i can think of


P.S. Ive even returned both items and got new ones and they didnt work either... my comp only seems to take in things ive installed previously to something... there is something blocking new mass storage devices.

Hey guys and gals,

I am having a problem with good ole' windows and my mass storage device. To set the scene I have a 40GB portable hard disk drive (basically a 2.5" HDD in a caddy) that uses a USB cable to interface with the computer.

It works like a dream and allows me to make all of my files, and life, portable. However when I am at home I leave it plugged into my PC as I turn it off between sessions using my PC.

If I boot the PC with the portable hard drive already connected it appears to be down to sheer look if windows picks the device up, 99% of the time it doesn't and I have to remove and re-connect the drive once windows has loaded.

In the situations when the device has not loaded during boot-up (just before I do my disconnect and re-connect trick) if I open the eject and remove hardware tool (windows tool, found in the systray) it shows the drive as connected. Interestingly, though, the drive does not have a letter after it in brackets. E.g. it would usually read:

Safely Remove Mass Storage Device - Drive (E

But when windows loads and its already connected it reads:

Safely Remove Mass Storage Device

I fear that I will end up being told that this is just another bug on the endless list of faults in Microsoft products. But any help would be greatly appreciated.

My 4 gig Super Talent flashdrive works fine on other computers, and it USED to work on my Windows xp, but suddenly it wants me to "install" it using the Hardware Wizard. And when I do try to install it, it gives me this message:

I STOPPED Installing, because i was scared.

I've had this flashdrive for seven months and it never showed me that message the very first time I plugged it in on my computer. It was instantly recognized and it worked great.
But that message started showing up after I installed the Logitech Camera driver for my webcam.My flashdrive wont show up in "my computer" and "disc management" anymore, but it shows on device manager as "usb (with yellow exclamation point) And when I try the "Safely Remove Hardware" before plugging it out, the "mass storage device" is not even there as if my flashdrive is not even plugged.
I tried unplugging the webcam, then plugging the flashdrive then rebooting, I even unplugged my keyboard, but nothing seems to work.I tried every USB ports on my computer too.

Im thinking of uninstalling the webcam driver, but i also need the webcam.Is there anyway that i could make my flashdrive work with my webcam, if not together, then at least when my webcam is unplugged?

Please help I really need my flashdrive to work again on this computer.

A:USB Mass storage Device problem

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.
