When trying to edit a partition on my hard drive,
Disk Utility says:
Couldn't modify partition map because the file system verification failed.
So I booted into single-user mode and typed in:
My computer then said:
The volume Macintosh HD appears to be OK.
I boot back up and check with
Disk Utility, but when I select the particular partition, it wont let me edit it in
Disk Utility and have it verified. It tells me to repair it. I try to repair but
Disk Utility can't repair this disk, and it needs to be reformatted. How would I go about doing this?
