Hi all - I've had this HDD lying around for a while now, and I decided that I should put it to good use with my Powerbook to store all of my recorded audio files. I bought a USB 2.0 enclosure, popped the drive in, and tried to format it. The drive appears as Maxtor Calypso in Disk Utility and the System Profiler, yet I can't mount it, erase it, or partition it. It does not appear on the desktop. Is my Hard Drive Dead?
