cbmformat formats a disk in a way that it is unusable
Brought to you by:

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.

Sorry, I mixed the numbers. The drive is not allowed to be
more than 0.6% slower than 300 rpm, that is, it must spin at
no less than 298 rpm.

Sorry, I again mixed the numbers. The drive is not allowed to
be 0.6% faster than 300 rpm, that is, it must not exceed
301.8 rpm.

This will be fixed in 0.1.0a and in 0.1.0.16. The solution is to
use a probing formatter (instead of the non-probing one as
now). This probing is done after writing, thus, it seldom
requires more than one extra round per speed zone.
