    I just had to force Mac OS X to reboot (it was stalled for good), and when it was done restarting, one of my external 300 GB hard drives was no longer recognized. It had 3 partitions, and I got the warning message in the Finder. Disk Utility doesn't see any partitions and DiskWarrior isn't any help. What should I do to get them back? I can't afford to lose the data on this drive. Thanks a lot in advance!

    Update: I did a search on MacUpdate for data recovery apps and here are some that I found. Please tell me if you have had any positive experiences with these programs. Thanks!

    P.S. Nothing is physically wrong with the hard drive.

    1) Plug the faulty drive into a different port
    2) If that doesn't help - try a different cable
    3) If you have a second Mac - try the drive with that
    4) Try the drive in a different enclosure
    5) If no joy with 1) to 4), Data Rescue II is a great choice.
