    New iMac 27" running Lion. I added a few external drives for different storage needs. 1 connected USB for backup/Time Machine, 1 USB for eBooks/pictures, 1 F/W800 for movie catalog and 1 USB for music. It's this last one that's driving me bonkers as it keeps unmounting every 20 minutes, then re-starting after a few minutes. Always giving me that lovely warning that I didn't disconnect the drive properly. It has it's own power brick (they all do) and is not connected to a hub. All the drives are the same brand FG Fantom so I'm at a loss. Why just that 1?

    Any ideas ?

    Hopefully, acosmichippo will chime in. Until then, my suggestions are to go into Disk Utility and and verify and repair the disk. You could also try switching USB ports with one of your other drives.

    Maybe it has a sleep mode?

    Thanks for the suggestions, unfortunately its still un-mounting. I moved it to the hub, off the USB hub to diff USB ports in iMac. Reformatted, etc. was going to google search today but Internet went down & tech was here all day fixing that. When it rains......

    Have you tested it with a different computer?

    i wouldn't hesitate to take it back for replacement, i wouldn't even try to quick fix it. imagine if you somehow find a quick solution and keep all your pictures there, and after some time HDD fails again but this time permanently with all your personal stuff. These days faulty HDD rate is pretty low,, you have 1.3 % chance to purchase faulty drive.
