Since switching from an Adaptec 1542CF ISA to a CSC NCR PCI scsi
controller, my ancient Micropolis drive has been filling my logs
with this stuff:

May 28 23:25:36 compound /kernel: sd1(ncr0:2:0): RECOVERED ERROR info:1857e6 asc:3,0 Peripheral device write fault
May 28 23:25:36 compound /kernel: , retries:4
May 28 23:25:36 compound /kernel: sd1(ncr0:2:0): extraneous data discarded.
May 28 23:25:36 compound /kernel: sd1(ncr0:2:0): COMMAND FAILED (9 0) @f10d3400.
May 28 23:30:09 compound /kernel: sd1(ncr0:2:0): RECOVERED ERROR info:1b6aa5 asc:3,0 Peripheral device write fault
May 28 23:30:09 compound /kernel: , retries:4

Is this a familiar problem for anyone?  I had the adaptec turned down
to 8MB/sec in order to accomodate this drive.  Is there any way to
throttle back the scsi bus xfers on the ncr controller?
