2 of the guys in my office have Perstores with ST4096's on their home 
machines.  They do work, but they both report occasional grinding noises 
similar to a normal configuration that is about to report a "Sector not
found writing Drive C:" error.  Apparently the Perstor does a
read-after-write and corrects weak writes by rewriting the sector until it's
satisfied.

Neither of them has ever had a problem reading the drives.  Still -- it's a
little scary.  I opted for a WD 1006V-SR2 RLL controller for my 2 ST-4096s.  
This formats the drives to around 118 MB.  I did this partly because of their
experiences with Perstor and partly because I'm running unix and I've never 
heard of anyone running Perstors with unix.
