  Giovanni (Moretti, G.Moretti@massey.ac.nz), the problem which you
described is that SuperSTOR apparently has less available space than you
think and/or the utilitiies (CHKDSK, XDIR, SSTOR) seem to tell you.

  However the, IMO, urban legend is something totally different and much
worse:

  The "OVERWRITE THE FAT" implies total disk corruption. You just have
less space than you think. Two totally different problems!

  This is probably the essential part. If the "I have about 3MB left on
C:" came from the DIR command, then that is your problem. You should not
believe the DIR command for a SSTORed drive (and the CHKDSK command even
less (I think this was, rightfully, mentioned in the README for the
Apr'92 update)). As I said several times before: This is *no* critcism
on SuperSTOR. DIR and CHKDSK work as good as possible. If you want The
Real Numbers (tm) then use SSTOR and XDIR.

  A simple method to determine how much you can still store on a SSTORed
drive: Do a "DIR" for the drive and look at the last reported number
("available"? (My PC is at home)) and divide it by two. That is the
number that you *always* *can* store, even if the data can not be
compressed. You *might* be able to store more if the data can be
compressed. Of course you can get this number from SSTOR too, but DIR is
probably more convenient.

P.S. Also the "Disk is full. Remove some files. Disk is still full and
     CHKDSK reports reserved units. Run DISKOPT. Disk is no longer
     full." behaviour is normal and can not be prevented. See y old
     postings for details (Time for a DR DOS / SuperSTOR Frequently
     Asked Questions list?).
