I recently installed a segate 238 harddisk and RLL controller in my
Xerox 6060 (a.k.a. att 6300). While the low level format program and
the dos format both said the disk was 32MB (614 cyls,26sectors, 4hds).
after setting up a partition to use the entire drive and formatting
that, the chkdsk routine only found 21MB. I'm certain someone else 
on the net described an identical problem, however, i can't find it
or the solution anywhere.
If I remember correctly, it may have had something to do with the ROM
bios. My machine has 1.36 . Do I need to upgrade to 1.43 or something
in order to use the whole disk? 
thanks for any help,
