This article is a follow-on to the one about the Perstor controller. It should
have much wider applicability, since any drive that works on the Perstor
controller ought to be fine on other RLL controllers.
What follows is a list of hard disk drives that have been verified to work
with the PS180 controller. This is the controller that gets 1.8 times the
'normal' data density out of a drive.
NOTE 1: This list is verified by Perstor, not the drive manufacturers. Drive
manufacturers never recommend using RLL schemes on drives that aren't
'qualified' for RLL. They would rather have you pay extra bucks and
get an 'approved' drive.
NOTE 2: I'd say that any drive on this list ought to work fine on any good
'RLL' controller. Experience may prove otherwise, we'll see!
NOTE 3: The PS200 (2 times normal density) controller imposes tighter
requirements than the PS180. Not all drives on this list will
necessarily work!
NOTE 4: If a drive isn't here, it may be ok, but untested by Perstor.
RLL-compatible drive list:
Manufacturer Drives
CDC Wren 2 94155-19, 36,38,48, 51, 57, 67, 77, 86
Lapine Titan 20
Maxtor 1065, 1085, 1140, 2190
(aka Newbury Data: NDR1065, NDR1085, 1140, 2190)
Miniscribe 8425, 8438, 8425F, 8438F, 3650, 3675, 6032, 6053,
6079, 6085, 6128

Priam ID130
PTI PT225, PT338, PT238R, PT357R
Rodime 3055, 352
Seagate ST238, ST4026, ST125, ST251, ST277, ST4051, ST4096
and....
ST225 rev #003 with S/N greater than 1,000,000
ST225 rev #003B or above
That's it! And whaddayaknow, Seagate *has* changed the ST225 guts, so the
recent ST225's WILL work ok with RLL. Nice to know.
