Remove Encryption - Repartition Disk
OS-X Lion I now have two useless FW800 external disk drives because I cannot turn off encryption and reformat the disk. (30 years ago, in DOS, this was called a "low level format".)
I think I need to use Terminal cammands diskutil eraseDisk or diskutil partitionDisk but nether of those commands work. Apparently, I cannot format the command correctly or diskutil cannot remove an encrypted partion. Help will be appreciated.
Mac OS X (10.7.4)
