[comp.unix.aux] disk errors

marcelo@sparcwood.Princeton.EDU (Marcelo A. Gallardo) (11/29/90)

I get the following error message every once in a while, when I am
logged in at the console. Does anyone else have the same problem or is
it just me? 

Disk read c3d0s0 Error: Recovered error, code = 0x17
Logical block 81144, physical blocks 81272-81279

BTW - The logical/physical blocks change. It's not always the same
numbers.

I was temporarily using a CMS Pro140 external drive, until I got my
REAL disk, and I too saw similar errors occasionally.

An interesting observation is that SilverLining reported errors with
hardware handshaking (one of the six handshaking options) on the CMS
drive.  I therefore chose one of the software handshaking options
(since I don't trust blind transfers).

Since A/UX uses its own drivers, it would, of course, be unaware of
the problems with hardware handshaking, and would ignore whatever
handshaking option was installed by SilverLining.  Therefore, I'm
not surprised that I had problems.  (I had no problems accessing
the Mac partition on this drive, however.)

I do not, however, understand what would cause hardware handshaking
to fail.  Is this an incorrect hardware/firmware implementation,
a defective drive, or a SCSI problem?  Although I'm no longer using
the CMS drive, I'd be interested in any theories on this matter.

(Anyone want to buy a used CMS drive, AS IS :-)
