I have been able to format 360K disks at 1.2 MB, but there starts to be a
fair number of bad sectors as the formating progresses towards the center of
the disk. I have also found that 360K disks formatted at 1.2 MB tend to
have a shorter data life span. Formatting 720K as 1.44 MB also seems to
result in a shorter data life span but not as bad as the 360Ks formatted at
1.2 MB, probably because the oerstadt rating is closer.
