I'm encountering some strange behavior with my 2090 controller and my
new hard drive.
Previous set-up:
A2000
A2052 2mb card
A2090
3650 Miniscribe HD 61ms access
New set-up:
A2000
A2052 2mb card
A2090
3053 Miniscribe HD 25ms access
June 16, 1988 release of HDdisk
I preped the 3053 and fed in all the bad sectors. There were about a
dozen. However, I am getting sporadic read/write errors on the drive.
Sometimes I can hit the requestor and the drive recovers fine while other
times it will guru with a corrupt memory list error. I ran a memory test and
everything checked out O.K. Is this a case of DMA contention on the bus
causing this problem because of the faster drive or is the problem that prep
doesn't really map out the bad spots on the disk? I never had any problem
with the 3650 giving out read/write errors on it's own accord.
