    Doesn't show external drive anymore but visible in the disk management


    I have a 2,5" 500GB external hard-drive with a single partition (NTFS).
    I can see it in the disk management utility (see attached screenshot) but it doesn't have a drive letter nor can't I assign one.

    Attached to another PC running Windows XP it says "unknown partition" but also error-free and NTFS.

    The problem could have been triggered by unplugging the harddrive without securely removing it.

    Yup it has about 300GB of files.

    Everything is greyed out besides delte volume (which I won't do with all the files still unsaved).

    Is this a usb drive? Go to Device Manager. Do you see an Unknown Disk there or an error icon for a disk?

    It shows up as Seagate FreeAgent Go (see screenshot).
    I can't assign a drive-letter (see the other screenshot).

    You can try uninstalling the drive in Device manager (right click, uninstall). Then click on the "scan for hardware changes" button and let the drive reinstall. If this drive with its own driver software, you can try reinstalling the driver.

    and due your information, you're already try to put into windows xp, but unknown partition.
    it's sounds like the hdd is corrupted. if the files important,that's you got the backup?

    Unplug this drive. Shutdown the computer, physically disconnect from the power outlet. Wait for 5 minutes, plugin your drive, reconnect power, reboot.

    Also, can you browse the drive contents in windows explorer?

    BTW, are you still using RC?
