    Hi,

    I have a 500GB external hard drive (USB powered) which just stays plugged into my computer at all times which I use for storing music, video, photos etc. When I started up my PC just now, it came up with an error message saying "You need to format the disk in Drive E: before you can use it", and it keeps bringing up this message whenever I unplug it and plug it back in again, or try to access it; but it was working fine just a few hours ago, and the drive hasn't been moved, bumped, unplugged or anything like that between when it was working, and now - so I see no reason for it to have stopped working. Obviously I don't want to format it as that would mean losing everything on it - including many files backed up from my old PC which I hadn't transferred to this new(er) one yet.

    I get the same error message plugging it into my desktop PC running windows XP.

    Any suggestions will be much appreciated!

    hiya,try this,open CMD and Type "chkdsk e: /f" - if your external drive mounts as Drive E... Replace this letter as necessary

    Hi,

    Thanks for your quick reply. I tried typing what you said into CMD but it says it isn't a recognised command. What directory does CMD need to be in?

    Thanks.
    CMD says:
    "The type of file system is RAW. Chkdsk is not available for RAW drives".
    But it can't be raw, it was working fine a few hours ago! Any suggestions?

    What you need is partition recovery software. I have had success with EASEUS Data Recovery Wizard Not free! But it gets the job done.

    Thanks for that suggestion, Lance1! Do you know of any free alternatives? The contents of the drive aren't really worth forking out cash for.
