    so i have it showing up in my disk management now thanks to your first article but it doesn't have a drive letter. I looked up some other articles but they all talked about changing the drive letter, how do i actually make one? it won't let me click on "change drive letter and paths" so i dont know how to make it have one

    Darn. I was guessing the PartMgr.sys file was missing but i see it displayed in the results you provided.

    When you say "it won't let me click on "change drive letter and paths" do you mean it's dimmed so you can't select it?

    Don't change anything but check any other disk or CDs that appear in Disk Management. Rt click and see are they all dimmed for that option? Or is it just the one USB drive dimmed for Change drive letter paths option?

    dimmed and its just the one, kinda jumped the gun and changed the drive letter of my disk drive to check if that was blocking it and that wasnt it

    Just occurred to me.... Does Disk Management show the drive is formatted NTFS or FAT? Because if it says it's "Raw" it's unformatted and you can't assign drive letter if unformatted.

    Which also begs the question: Did you think you had data on the drive???

    Very odd

    Could you do a screen capture of the Disk Management window?
    Hit PrintScreen (might be listed as something like PrtScr) upper row toward right of keyboard. Paste into Programs->Accessories->Paint. Save as a .jpg file and attach it to post

    Please provide a list of your current Windows services
    1) Download Serviwin Run it and click View->Services
    2) Click on a service then Ctrl-A to Select All, Ctrl-C to copy, Ctrl-V to paste into Notepad (Programs->Accessories->Notepad)
    3) Save as a .txt file and attach to next post
