[comp.sys.ibm.pc] Occasional Posting of Good-for-RLL Drives

pete@Octopus.COM (Pete Holzmann) (10/25/89)

What follows is an old list of hard disk drives that have been verified to work
with the Perstor PS180 controller. (This is a controller that gets 1.8 
times the 'normal' data density out of a drive.)

Perhaps somebody can become the keeper of this list, and take continual
survey input on drives that do and don't work well under RLL. (Note that
ANY drive can be bad; simply because a sample doesn't work under RLL doesn't
mean that all samples won't work! My only personal bad experience was with
an RLL-rated 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: If a drive isn't here, it is probably ok, but untested by Perstor.
