flash drive does not work anymore

jessjarvis7
I was using my flash drive on 1 computer, stuck it into another computer and now it does not work. It shows up as being there under "my computer" but it says "please insert disk" when i click on it. I am desperate, can i buy one of these restore disk downloads that are 45 - 75 dollars? I tried a free download one and it said nothing could be found. Is there some type of issue involving the 2 computer's xp's?

    chkdsk driveletter:/f on the Drive.
    <br><br>
    Try rebooting the computer without any USB devices attached. Then plug in the USB drive, right click on My Computer, select manage, and then click ?Disk Management.? If the drive is not present in the Disk Management window or if you are not able to access it, then the drive may have failed. In this window you should see all of your connected physical drives, their format, if they are healthy, and the drive letter.
    Change the drive letter of the drive. Right-click on the drive in the list, and from the resulting menu select "Change Drive Letters and Paths"
    Click on Change so you can change the drive letter. Click Change.
    Select a new drive letter from the drop down list, preferably the one that is not normally used for this drive.
    Click Yes on the confirmation screen and you are done.

    Caution: The cause of unpredictable behavior in a USB drive is often found to be the incorrect removal of a previously connected USB device. When removing USB devices right click on the ?Safely Remove Hardware? icon in the menu bar tray. This is usually found in the bottom right hand corner of the monitor. Once you have clicked on the icon, a menu with a single selection should appear. Click again on that selection to see the ?Safely Remove Hardware? window. Select the correct USB device and click the ?Stop.? When you receive the message that it is safe to remove the device, unplug the USB device from the computer.

    Click Start and in the Run box type in cmd and press Enter.
    At the command prompt type in chkdsk U:/f 'the drive letter that you just added:' EG: U: and press enter.
    If it finds any discrepancies it should fix them.

    WARNING!!!!
    Any changes you make in the registry can make the computer unstable or UN-operable.

    Delete Usb Drive Letter via Registry to Remove Conflict .

    In Windows operating system especially Windows XP, when plug in external USB or FireWire mass storage device such as USB key, flash drive, portable harddrive, the drive is not been assigned a drive letter by the system, hence the USB drive or FireWire drive is not showing in Explorer and no AutoPlay or AutoRun window pops up, although the device has been detected, in Safely Remove Hardware (show device but with no drive letter) wizard. The cause is probably due to ?stupid? behavior of XP where it won?t find an available letter from free letters pool when the USB or FireWire external drive which has previously mounted and assigned a drive letter is been inserted to computer USB or FireWire port again, but that previously allocated drive letter has been taken up and used by another storage devices. Another possible reason is all 26 letters in alphabet has been used, but this situation is rare and unlikely.

    There is a solution to USB or FireWire drive not showing in system error. However, the disconnect conflicted storage device to free up the drive letter fix may not be practicable or usable by some, such as computers which are on a network or system running data transfer activity to all its drive assignments continuously flow without stopping, and thus disconnect or reassigning any mapped drives, networked drives, removable drives or other storage drives is not an option.
    In this situation, there is another workaround hack to fix the no USB or FireWire drive issue. The workaround fix relies on the registry tweak below to change the drive letter that has been previously assigned to the mounted USB or FireWire portable mobile flash or hard disk drive. Or if users wish, can opt to delete any reference to the detected drives by the device so that when the storage device is plugged in again, the whole drive letter assignment will be start from fresh, and clean.

    1.Login to Windows as an Administrator.

    2.Open Registry Editor by typing regedit (or regedt32.exe in older Windows prior to XP) in Run command of Start Menu and then press Enter.

    3.Navigate to the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

    4.Optional step which not required in Windows XP or later, right click on MountedDevices, then select Permissions. You can also click Permissions from the Security menu.

    5.Optional step which not required in Windows XP or later, check the option to make sure that Administrators have full control to the registry key. Change and revert back this setting when you are finished with the reset of the steps.

    6.If you run above 2 steps in OS earlier than Windows XP, quit regedt32.exe and run regedit.exe.

    7.Also in the HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices registry branch selected, in the right pane, find and locate a registry value which represents the troubled USB or FireWire drive. The registry key should have the name that resembles the format of \DosDevice\X: where X can be any alphabet letter which corresponding to your physical system drive letter.

    Here?s a guidelines that you can follow to quickly determine which registry key is linked to your conflicted drive letter:
    Exclude \DosDevice\A: and \DosDevice\B: which normally reserved for floppy disk drives.
    Exclude \DosDevice\C: which normally is the system root drive.
    If you have more than one fixed hard disk drives, then any drive letters that are using by them is not possible linked again, UNLESS the additional hard disk drive is added AFTER you first use the USB or FireWire device that now unable to show.
    Same case with CD-ROM or DVD-ROM optical drive as above reasoning.
    If you have inserted and mounted a lot of thumbdrives, USB flask drive, or external hard disks before, you will likely still see a lot of remaining registry values that you won?t know which is which. In this case, double click on each remaining registry key values to view its binary data. Inside the binary data, there will be trace of the name of the device that this registry key represents. For example, figure below shows a Sandisk Cruzer micro USB flash drive.

    With this information, search for a registry value that contains name of your USB or FireWire drive brand and model that having problem showing up in Explorer.

    8.Once the correct registry value is determined (for example, \DosDevices\F:), right click on the registry value name, and the select Rename.

    9.Change the drive letter (example F) to another unused drive letter that hasn?t been used by another other drives, then press Enter.

    10.Now insert and plug in the USB or FireWire device into the port again (if it?s already inserted, take it out and re-insert again). The drive letter for the USB and FireWire should now appear and you can use the drive normally and properly again.

    11.For OS earlier than Windows XP which you have previously change the permissions for the registry key, quit Regedit.exe and start Regedt32.exe, and change the permissions back to the previous setting for Administrators (which should be Read Only).
    It?s also possible to simply delete the devices registry keys instead of renaming it. Deletion is helpful is users really can?t find the the registry value for the drive letter that having problem. But make sure that you do a backup for the registry branch by exporting MountedDevices key, as mistake may cause your system unbootable. The delete all possible USB drives, FireWire drives and external drives which have drive letter temporarily only when inserted in the system, and DO NOT delete any of the fixed hard disk drives or CD/DVD optical drives registry values.

    Please post back if you have anymore problems or questions.
