Disk encryption hangs with disk I/O error
First time trying to do a basic disk encryption. Window says that encryption is paused, but trying to resume gives me the beach ball. Eventually the beach ball goes away, but I'm still left in the same position as before trying to resume. I can't decrypt or continue.
At the system prompt, I tried the following on another forum thread suggestion:
$ pgpwde --status --disk 0
Disk 0 is instrumented by bootguard.
Encryption process interrupted by disk I/O error
Current key is valid.
Total sectors: 488397168 highwatermark: 63288360
Request sent to Disk status was successful
I ran Disk Utility before trying to encrypt; it found an error (don't recall the type?), and running a repair seemed to fix the problem.
How can I extricate myself from this morass?
