I have a G-Drive mini (320 GB / 7400 rpm) that was working fine until yesterday, when my system (MacBook Pro 17" unibody / OSX 10.5.7) crashed. After forcing a shut down and rebooting, I discovered that my G-drive mini would no longer mount. Although the drive does appear in Disk Utility, all options (including "erase" and "format") are grayed-out/non-selectable. The drive still spins, but it appears to my computer as being unformatted, having a TOTAL capacity of 0 (see image). And when it is connected to my computer, it significantly slows the boot-up and shut down times.
I have been using the FW-800 interface. I tried connecting via USB 2, but it just make a clicking noise (it may need the optional power supply, which I don't have).
Any ideas???
