Hi!
[DEBUG] FORMAT 0.92a, selected drive B:

OVERFORMAT: 1494k in 1200k drive. Good luck!

No gap length known for 18 sec/cyl. Good luck with BIOS value!
TWEAK: Sectors per cylinder in DDPT set to 18
Well, it did say "good luck". Formatting to 1494k in 1200k drives
does not always work. The log later shows that 1200k did work :-)
The next question would be: Did you explicitly ask FORMAT to use
1494k format? If not, have you used a floppy with that size right
before starting FORMAT? If yes, has this worked with other disks?
Is your drive a classic 5.25inch 1200k drive? Any specific details?
Regards, Eric
Here is the part which shows that 1200k format did work for you:
