Format the External Hard Drive from Hell I have an external drive that is basically completely screwed. It’s just for backups, and I have redundant backups, so I don’t care about losing the data, I just want to completely format it and get it working again. (I highly doubt it is a physical issue with the drive)

This is basically the state the drive is in now:


The drive has two partitions
One partition will mount, but cannot be unmounted, even forcing through Terminal
The other partition will never mount
Whenever the drive is connected, Disk Utility will stop working
I managed to get the drive to respond and unmount by killing the process fsck_hfs
