[snip reasons]

OTOH, I degaussed a known-good disc, and FORMAT.EXE was unable
to format it under FreeDOS, whereas it was able to under MSDOS
6.0. It failed right away, reporting the FORMAT TRACK call failed.

Nonetheless, it was not the BIOS FORMAT TRACK which failed
in the earlier attempt.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
