USB drive

reyferns
If we double click on USB flash drive it gives error message "Access is denied". Same if go to explorer and open , it opens.

Also on some PC if we open the flash drive, it opens sucessfully.

Why this happens?

    I found that if i boot XP in Safe Mode then i can see and open the Flash drive, which is a bit ironic really. points towards a driver issue.

    just put your drive in a differewnt computer and format. works every time for me with verious brands of flash drives. Works best if you use a xp machine for a vista and 98 for a XP.

    The error is caused by a change to the Autorun.inf file on your flash drive. (It's just an annoyance from some spyware/malware)
    How to fix - First go to Windows Explorer (or My Computer). The autorun file is hidden and labeled as protected OS file. Go to Tools > Folder Options.
    In Folder Options dialog box click on the View tab. Under Advanced settings: look for Hidden files and Folders. Click on the ?Show hidden files and folders? option. Next make sure you scroll down and UNCHECK the ?Hide protected operating system files (Recommended)? option. Click OK.
    Since you?re still in Windows Explorer/My Computer ? Right click on your USB Drive and click on Explore. Find Autorun.inf (most likely grayed out and labeled just ?autorun?). Right click the file and choose properties. Uncheck ?Read Only? option on the bottom. Before you click OK ? also click on the ?Change?? button and choose Notepad as the application. Once you click OK you should be able to double click the file and open it in Notepad.
    When the file opens ? erase/delete EVERYTHING! And save it. (You can go back and hide the hidden files and folders again ? also make sure that you make the Autorun file Read Only.
    Unplug/disconnect the drive, then reconnect it.
    That should be it.

    Hi,

    Look in ADMINISTRATIVE TOOLS - COMPUTER MANAGEMENT - DISK MANAGEMENT and check that the USB device has been assigned a unique drive letter. I have found that sometimes it is assigned a letter that already exists for another drive. Change it to a free letter.

    Good Luck

    Yeah Thanks, but i've tried that. I can see the flash as a drive, but cant get into it. Also interestingly enough Disk Management doesnt report it's file system type. C:Drive is NTFS that's OK, but the Flash should be FAT32 (or 16) which doesnt show

    Interestingly enough, the Data Doctor Pen Drive was able to get the files off the Flash drive. I also read something about it's a problem with permissions in the resgistry, but no detail on what ones !

    Hi David,

    Did you find a fix for this problem. I've had the same or a similar issue for months, so I'm interested in any possible solutions.

    If you can please let me know how you got on?

    Kind regards,

    I have looked around a lot and tried various things that have fixed other peoples problems, but in the end the only thing that did fix it was reparing XP from the original CD. It did mean i had to re-apply all the windows updates etc, and reinstall a few things that got messed up by it (firewall and antivirus) but I'd say considering the time spent looking for a fix, if i'd done the repair to start with I'd have saved myself a few weeks without USB
