I just installed a new Perstor hard disk controller in my Zenith 386 PC.
The controller is Perstor's new 16-bit advanced RLL model PS180-16F.
This controller gives me 90% more storage on my CDC Wren II model 51 hard
disk (originally on an MFM controller) resulting in 78 MBytes of storage.
The installation was fairly easy, and everything *does* work. The read
transfer rate went from about 160 KBytes/sec with the MFM controller to
399 KBytes/sec. I am very happy with this :-).
HOWEVER - There seems to be a problem with writing. My hard disk activity
light flashes on when I do a copy, for example, and then goes off for a few
seconds, then flashes on again, then stays off for a few seconds before I
get the DOS prompt. Copying a measily 178 KByte file takes about 6 seconds!
When copying multiple files to a floppy disk, the floppy disk activity
light goes out between files.
Anybody have any idea what might be happening?
