3 cbmformat formats a disk in a way that it is unusable - ID: 1066199

Last Update: Comment added ( strik )

Details:

If cbmformat is used to format a disk, the disk is
unusable, has read/write errors, or shows other
unexpected (and unwanted) behaviour.

Andreas Boose found the reason: cbmformat is highly
picky on the RPM of the drive. If the drive runs at approx.
280 rpm (or lower) instead of the (nominal) 300 rpm, it
overwrites part of the track it has just written.

This bug will be fixed in the future.

This probing is done after writing, thus, it seldom requires more than one extra round per speed zone. -- Spiro.
