Funny thing about that--which goes to show you some wisdom about old
software vs. new. While Windoze can barely figure out what kind of disk
you have in the drive (and sometimes even if there's one in the drive), I
powered up an old CP/M system here to read some old GCR disks.
One of the first things that I did was to format a diskette. So, I typed
in the command and gave it the usual "G" to go and format and was greeted
with the message:
FORMAT ABORTED--SPINDLE SPEED IS 7% SLOW.
The cure was to get the drive testing program out and tweak the pot on the
tach board, but it was a lesson in how, sometimes, the old software on
those poor crippled machines is far from brain-dead.
