>Description:
When I mounted the dos partition on a 3.2GIG ide (LBA mode with
128 heads) it caused a large number of errors complaining
about clusters, then even unix commands did not work.
It seems to be related to the heads-multiplier (to reduce
cylinder count for silly DOS-WINDOWS). When head count
is 64, it has not exhibited such errors, as I have it running
on my laptop without problems.
>How-To-Repeat:
Mount a 128-head dos partition
>Fix:
? :-)

This is evidently another instance of the MAXBSIZE < FAT cluster size 
problem which was identified by bde and fixed by dyson in late 1996.
