Windows XP Pro not seeing a USB Mass Storage Device

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

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

Preferred Solution: Windows XP Pro not seeing a USB Mass Storage Device

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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 a problem.

Symptoms :
- Any USB Mass Storage Device won't appear in my Windows Explorer.
- It will appear on the bottom right screen as safely remove hardware, and you can safely remove it.
- Device Manager can detect it in two locations : Disk Drives, and Universal Serial Bus Controllers (as USB Mass Storage Device). In their properties it says "This device is working properly."
- Disk Management cannot detect it. It will only showed my CD Drives. And I've already assigned the CD Drive letter to something elze (Z.
- My mouse and My soundcard work perfectly in all USB port.
- All the devices that I've plugged to my USB work perfectly in another computer.

I've tried these solutions (It didn't work) :
- Tried another USB Flash Drive, Mp3 Player, and my External Harddrive
- Tried to plug it to all the USB Port.
- Tried to delete UpperFilter
- Cannot assign the USB Mass Storage drive letter because it won't be detected in Disk Management.
- Tried to uninstall and reinstall all the USB controllers in Device Manager
- The Virus & Malware scan result were nothing. (Using latest Avaast and Ad-Aware)
- Tried to delete dosdrives in registy.
- Unchecked all "Allow computer to turn off this device to save power"

Ok... I've done all of those and still can't read all my USB Flash Drive, Mp3 Players, and my External Harddrive. All help and suggestions will be greatly appreciated.

The problem originated after i tried to "low format" a USB memory that a coworker asked if i could fix, it had a "Protect against writing" message, i was not able to format it, but i was able to copy stuff from it, but not add new stuff to it. I tried several google tutorials, changed registry values and run some CMD commands, found the same information on several sites with no luck. The USB memory remained "locked".

Long story short, i gave up, when i disconnected the USB drive i noticed all my shortcuts from the desktop disappeared? and also all my bookmarks in Firefox?, i was astonished.

Now 4-6 days ago i wanted to copy ome videos and a portable version or MPC-HC, but then i connected my USB 32gb memory flash ( my personal USB memory, not the one i was trying to format) into my 3.0 port, and well... it was not found in my computer folder !!. I tried to look into the manage device > storage device to see if it was a problem with the "letter label" but no! is not there either!. And yes, the USB worked on my other laptop as normal. All my other USB peripherals work perfectly, mouse, keyboard etc.

Next i went into device manager, and found a yellow triangle as shown in the picture, and when i clicked the "show hidden devices" i found that there was the name of the usb that i tried to low format !! greyed out!, I instantly uninstall it with no luck from the device manager, is not there anymore since i saw it, but even so ...

Have recently received delivery of a new computer (based around the Athlon dual core 64 chip) and am looking to transfer my existing external hard drive and DVD-rom. However when I connect up my external HDD, Windows XP media centre edition 2005 initially recognises it as a new USB device but after a short period of searching returns the message - hardware not installed because wizard cannot find necessary software.

According to installation leaflet for the external drive, the driver for the hard disk is already built into the windows XP system. From what I understand the driver it should be loading is - USB 2.0 Hub

(When I attach the external drive to my old machine it initially recognises it as a USB device then shortly after it identifies it as a USB mass storage device. The new machine only gets as far as identifying it as a USB device.)

Is there any way of forcing windoew on the new machine to recognise it as a USB hub / mass storage device?

Grateful for any advice on this.

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.

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.

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.

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 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?

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, 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..

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

This is going to be a long winded post, but I want to give as much info as I can with the problem I’m having. I worked on my neighbor’s Dell Dimension 3100 desktop pc recently.

2. Ran Adaware 2008 Free, Spybot S&D, A Squared Free, Hijack This, CCleaner.
Removed all threats, etc. successfully.
3. Upon numerous reboots the BSOD with the same message indicated above
reappeared and the pc would freeze.
4. Replaced a bad RAM stick with a known good one.
5. Formatted and reinstalled Win XP with the Dell provided disk and Dell provided

7. Reinstalled all her personal software and All Windows updates including SP3.
All worked flawlessly.
8. Connected to the Internet--no problems there. Man, I’m on a good roll now so I

I just purchased an Sandisk MP3 Player for my daughter. When I connect the player to her PC, I am prompted to load the drivers (which I have done at least 5 times now) but the device does not then appear to be recognized by her system. It does not appear as a device in My Computer or in Windows Media Player. She has a eMachines T3990.

I did some research and found the MTP Porting kit on the MS web site. I downloaded it but it made no difference.

For comparison, I connected it to my wifest PC (eMachine T3624). It prompted me to install the drivers and once I did, I could sync it with Windows Media Player and it shows in My Computer.

I talked to Sandisk and they told me to reinstall WMP v11 which was already on her machine but I did as requested and it made no difference. My wifes PC also has v11 (exact same version on my daughters pc).

Next, I reviewed the USB serial buss controllers in Device Manager. My wifes pc had two entries: USB Mass Storage and USB Composite Device that were not showing on my daughters PC. I copied to two drivers and was going to load them on my daughters pc until I discovered that the drivers were already on her pc -- same size and version.

The MP3 Player requirements state USB 2.0 but I'm not sure that I have that version on either of these two pc's. They are less than 3 years old. I'm not sure how to determine the version.

I am stumped. Is there some way to force all of the USB drivers to load again?

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.

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.

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 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.

I’ve been busy with my computer. In the last week I’ve installed new monitor, have had to take out my AGP 8x card and put it back in and I’ve had to take my PC2700 512mb stick of RAM out and put it back in.

So I might have jostled something in my computer.

I have three drives on my computer, a WD 20 IDE drive in C (win98se), a 40GB Seagate IDE in D (WinXPsp2), and a USB mass storage device. The USB device is 250 GB.

My USB device has three partitions, G, H, and I.

I’ve noticed in the last couple of days some knocking coming out of my usb drive. So I’ve taken it out and put it back in. It is connected to my computer via a USB to IDE cable.

Usually this does the trick but today I had some really bad knocking. I took it out and rearranged the power supply wires.

Now my usb device doesn’t show up at all on my computer.

When I am in Win98 and plug the usb cord in, it tries to show up but I get a yellow dotted line at the top of my computer screen and then it reboots.

When I plug my usb device in WinXPsp2 my computer automatically reboots.

My usb drive is less than a year old. I purchased it in December from Tiger direct. I also purchased a three year extneded warranty. It is a WD Caviar 250.

It seems to early for the drive to wear out.

Also, something else: When I reboot my computer I see the notation on my DOS screen

USB to Atapi Bridge

I used to see

USB to Mass Storage Device.

A:Problem with USB Mass Storage Device

Read other 14 answers

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.

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.

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 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.

I have a portable burner but can't find D drive. I opened the mass storage case earlier and disconnected the burner. To my amazement it worked, D drive was back. Not for long as soon as I rebooted it was gone again. I have the same problem with the laptop.Both computers have worked with it in the past. I can see the mass storage in device manager under USB ports but can't find the burner. I have recently reinstalled XP,but only on the desk top computer.This is the computer I have been using it with.Somehow during or after the install the burner in the tower and the portable burner traded drives.I hope someone can help.It's all pretty new to me but I'm learning to love playing with them.

I recently got a new computer and from the moment I've started using it, in the tray on the taskbar, the safely remove hardware icon is always there. I click it and it says "USB Mass Storage Device". The thing is, I have nothing connected to any of my USB ports. It's not bothering me or anything, I was just curious as to what may be causing this.

Hello everyone.

I have a PC with Windows 7 Professional 64-bit installed. My problem is that with some usb devices I get an error 28. These devices are working on other PC. For example I have 2 usb sticks 16gb. The one is working fine, and the other has an error 28.
I searched for viruses with Microsoft Security Essentials, Malwarebytes and combofix and nothing was found.
Tried system restore, and also shut down the PC and disconnected it from power supply, just to discharge the capacitors. But still the same.

I run for a second time Malwarebytes, it found more things to delete and then everything was working.

hey everyone, I have an in internal hard drive in a USB enclosure, and the hardware works, but windows will not recognise it. I believe i need a new driver. can anyone help?? Thank you!

A:USB Mass storage device drivers

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’ll try to keep it short as possible. Been reading the do’s and don’ts most of the day and made it a long way through the elephant in the room post. Already knew the do's and don'ts but wanted to make sure. Haven't been here in a while.
One problem - got a few more, slow of course - I can barely write this.
Each time I reboot my pc, I get an icon in my systray to remove new hardware. This I really only noticed today so I don’t know if it’s always been there - 2nd/extra computer, desktop/changing to Windows 7 I hope with your help.

Second problem, only mention it here because it might be realted. I bought this computer used. It’s obvious that he tried to clean out his data first and most likely got more than his data or it had a bad effect. From the first time it was started a pop-up says:
"WELCOME TO THE FOUND NEW HARDWARE WIZARD! (You lucky JERK!) "This wizard helps you install software for: PCI device".
Tried the wizard a few times - Windows can’t find the software. I don’t have a disk that it will take either. I just close it but it pops back up every few minutes. Have no idea what it wants or what a PCI device is to try tracking something down.

According to the official specs ( http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c00210099 ),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.
To identify the device with missing driver, please follow the below steps.
1. Open RUN dialogue ( Win key + R ) and enter Msinfo32.exe in it.
2. When the "System Information" tool opens, choose File -> Save and give a name a name of your choice. 
3. Download and install 7-Zip from http://downloads.sourceforge.net/sevenzip/7z920.exe
4. Now right click on the saved file and choose  7-zip --> Add to archive. This will compress and considerable reduce the file size.
5. Attach the file using More Reply Options --> Attach files with next reply.
