The standard disk format on my 68K MINIX box is: 5 sectors 1024 Bytes each, 80 Tracks, 2 sides. = 800KB /dev/fd0..3 correspond to 4 drives /dev/fd4..7 correspond to the same drives, but to th standard 720K format. Other formats should not be used: 10 Sectors of 512 Bytes are too long in my opinion (require a drive with little tolerance on the rot. speed), AND I WONDER HOW SOMEONE CAN CALL A FORMAT WITH MORE THAN 80 TRACKS 'SAFE'!!! C.v.W.

I called this format safe in a atari-st context. The standard disk drives in a atari are able to read/write upto 11 sectors and 83 tracks. But due to statistical fluctuations some (above numbers are pushing it) drives does not support these numbers. (Some drives (mine :-), but more) support 12 sect. Some drives (do not dare to try) support upto 87 tracks) Going down 1 step in both directions gives the 82/10/2 format i call safe. Also quite some people do this also as many PD formatter for the ST support this format.
