    How is the drive formatted? Is it Apple Extended Format (Journalled) or is it a Windows format like FAT32 or NTFS?

    It it is in the Apple Format, run Repair Disk on it.

    Have you tried a restart or a shutdown and reboot of your Mac yet?

    it's os extended journaled , will running "repair disk" damage or delete any of the data on the partition ? I'm afraid of losing any of the data if repair disk doesn't work..

    Can you try it on a different mac, it might be a problem with the usb rather than drive.

    It won't be the drive then, the problem is the usb hardware in your mac, or driver/firmware problem.
