I have a Mini Server (2x500, Snow Leopard) and it the system drive recently had a bit of a meltdown. I thought I could fix it by erasing the drive, reinstalling OSX Server and restoring from a backup. I can't do that though, because disk utility (both in the OS and off the install disk) will not allow that drive to unmount for any erasing/installing to happen. What's really wierd is in both Disk Utility and Disk Warrior a slew of "phantom drives appear" when the mini is target booted. They refuse to be ejected/unmounted. Pic below. Does anyone have any idea how I can unmount this drive to wipe/reinstall it? I've tried disk utility & disk warrior but neither can handle the system drive. I also tried the manual zeroing out command in terminal (sudo dd if="/dev/zero" of="/dev/rdisk1" bs=8m) but after a while it began returning reports of inactivity with timestamps. Any help is greatly appreciated!
