Shortly after my RSCC received its first Tandy 2000, I took an old Model
One diskette (SSSD, 35-Track) and formatted it in the T2K with full
verify enabled. It formatted fine with only two bad tracks reported (the
diskette was at least four years old, and had been reused many times).
Of course, back in those days I wasn't bright enough to place some data
on that diskette, put it in a safe place for a year, then check it for
data retention. I just wanted to see how it would format.
