I'm trying to add a SCSI disk to my system, and ran into a perplexing
problem.
I've just installed an NCR 53C825 SCSI controller. The controller
worked great under FreeBSD 2.1R, but the old surplus Seagate I was
using with it sounded like a jet engine. (I had no problems
partitioning, formatting, etc, the Seagate drive.) I'm trying to
replace the Seagate with a new (much quieter) HP drive. The HP drive
works just fine under DOS; at least I could partition, format, and
copy files onto it with no problems. Under FreeBSD 2.1R, all is not
so rosy. It probes just fine:
> ncr0 <ncr 53c825 wide scsi> rev 2 int a irq 9 on pci0:18
> (ncr0:0:0): "HP C3725S 6039" type 0 fixed SCSI 2
> sd0(ncr0:0:0): Direct-Access
> sd0(ncr0:0:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8.
> 2047MB (4194058 512 byte sectors)
However, when I try to run `fdisk sd0' from FreeBSD, it fails claiming
an I/O error or `device not configured', and the following perplexing
message is dropped into the log file:
> sd0(ncr0:0:0): ABORTED COMMAND asc:4e,0 Overlapped commands attempted
Usually this is repeated several times. Any attempt to manipulate
this drive (scsi, fdisk, disklabel, dd, etc.) meets a similar failure.
Any clues? I'm going to start phoning mail-order companies to see if
I can find a good 1.5-2gig drive within my price range, but if all
else fails, I guess I'll break down and add another IDE drive. <sigh>
