I run a Perstor here , MAKE SURE YOU ORDER THE 16FN (network model) , and it
runs LIKE A CHAMp. NO problems whatsoever. The folks at both ISC and
perstore were a bit surprised I might add. 

Here is what I got...

   74.3 or so megabytes from my ST-251
  151.4 or so megabytes from my ST-4096

NO problems from either drive, no special installation tricks...

1) Boot under DOS
2) RUN PERSTORE's low level formatter (do a full surface verify)
3) Run PERSTORE's CMOS setup.
4) Install UNIX .. DO >NOT< format the device (would blow away the 'custom
   format) .... and DO ANOTHER READ/WRITE  VERIFY.

Thats it , you are all set from there on in.

One thing , MAKE SURE THE HD YOU WANT TO RUN HAS < 8 defects (ISC only
allows ?256? bad sectors, and any bad track on the drive is 31 of em!).. 

>it would give me 228Mb instead of the 120 that these

Sounds about right

Am posting here and in email.

IN SHOT -- THIS THING WORKS and is the greates undiscovered treasure for
small UNIX owners , a 90% HD space increase for approx 160$ is NOT to be
laughed at!

(grin)
