What always got me at the time was retry is understandable, but what the heck is the difference between abort and fail? I don't want to complain too much it was probably in the manual, but as a young teen during my DOS days (there are manuals? read?) The distinction was lost on me.

My understanding today is that one of them(fail?) gives the application a chance to do something clever. Did any application actually handle this gracefully? Something like, Disk 11/15 error(fail) Please put in recovery parity disk.
