While i was testing my formatter i built a 32 meg partition on one
disk.  To test it I filled up by copying  my 16 meg C: partition to it
twice.  The setup is source C: on drive 1 (SCSI 0) and destination G:
on drive 2 ( SCSI 1).  After 16-20 meg of copying, it gets noticeably SLOW!
I suspect this is a consequence of clusters being allocated 1 at a time
and the FAT bewritten after each allocation.

Oh well, its nice to know that TOS1.4 will support 32 MEG.  Its just not
time effective to make partitions that large when one can easily put
12 partitions on a disk.
