[comp.sys.ibm.pc] Priam hard disk drives with EVDR.SYS...how weird are they?

Hi. I have encountered several Prima hard disk drives which use a special
device driver (EVDR.SYS, I think) and special partitioning software.  The
mnnual says they use a special system for partitioning and formatting and
very strongly warn you not to use other software for this, including DOS's
FDISK and FORMAT.  I've also seen other hard disk management products that
warn you not to use them with these Priam drives.  I've played them enough
to confirm that they are indeed strange.  Anybody know exactly what's going
on with them...how they're formatting and partitioning systme differs from
the "normal".  

I would guess that they're using the landing zone track for something special 
and that the controller needs (many third party programs use the landing zone 
cylindar for testing and other things).  But that's only a guess.
