    Flash Drive Missing after Rebuild (WinXP Pro SP2)

    I'm using WinXP SP2. I did a non-destructive Total Rebuild reinstall and everything works fine except that I can't see my flash drives anywhere (My Computer, Windows Explorer...). The machine recognizes the drives because:
    I get a pop-up message telling me it can run faster with USB2; The "Safely Remove Hardware" shows "Safely Remove USB Mass Storage Device"; Clicking that gives a pop-up saying "Safe to Remove USB Device". I've gone to Computer Management and find that there's no drive letter assigned. I've tried to assign a drive letter both in Normal Boot and in Safe Mode with Administrator Login. I can open the drive and see the files while in Computer Management but the drive assignment disappears when I reboot and I still can't see the Flash Drive in "My Computer" or "Windows Explorer".
    Can't use the drives if I can't see them. Anybody have any ideas?????

    Do you have any mapped network drives? If so, this article may help.

    John,
    Thank you. I did know about that particular problem but I have no mapped drives. I did change the drive letter to a higher letter just in case but it didn't help.

    This problem has surfaced before in the Lounge. A search for "flash drive" in the forums may yield an answer.

    When you rebuilt the machine did you do ALL of the Windows Updates yet?
    You may be back at SP 1 or even SP 0.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    Re: Flash Drive Missing after Rebuild (WinXP Pro S

    As I understand your problem, after you assigned drive letter for your USB drive from Computer Management applet and then disconnect the drive, on the next connection Windows does not "remember" your USB drive, is it correct?

    First, check your hard drive for errors: click Start | Run, type CHKDSK /F and hit Enter. Confirm your choice and reboot your computer.

    Then logon to the account with Administrator rights and make sure you have the right to modify the Registry. The best way is to create a "New key" with empty string value, then close and open Registry Editor. If "New key" is still in place, you have the rights. It is better to delete the key after the test.

    After the test connect your USB drive and form Computer Management applet assign the drive letter. You can also create Restore Point after this step (Start | All Programs | Accessories | System Tools | System Restore).

    Disconnect your USB drive and check if Windows "remembers" the drive.

    Re: Flash Drive Missing after Rebuild (WinXP Pro S

    Okay, I've done all that kaplinb suggested with the following results:
    Ran chkdsk; Made a test registry key, closed the registry editor, reopened the registry editor and the key was still in place then deleted the key; reconnected the flash drive, went to Computer Management, assigned the next appropriate drive letter, then made a restore point.
    Disconnected the drive and Windows **did not remember** the drive. I had previously done all the above except make a test registry key but I did it all again anyway. I hate to do it but maybe the only way out is to do a complete reformat and Windows reinstall. I did a non-destructive no-reformat Windows reinstall as recommended by Langa and everything else worked okay with all of the software working fine. This problem really has everyone stumped. Any other ideas will be greatly appreciated.

    What happens with other USB devices plugged into that USB port ?? No one has mentioned defective hardware yet. The USB port, not the flash drive (but I would check that on another PC too).

    Re: Flash Drive Missing after Rebuild (WinXP Pro S

    I had the same problem a year ago, with 1 of 2 USB ports at the front of my PC. After a while, I tried connecting through the other port and that triggered the "new hardware found" routine again and this time it sticked. But only if I use the 2nd USB port. Using the 1st USB port still results in the USB stick not seen. Never figured out what caused this and how to cure it. But connecting to the 2nd port works fine, so I didn't waste any more time on it...
