I'm running FreeBSD 2.1-STABLE on a Pentium 133 box:
# uname -a
FreeBSD xxxx1.jpl.nasa.gov 2.1-STABLE FreeBSD 2.1-STABLE #0: \

earle@xxxx1.jpl.nasa.gov:/usr/src/sys/compile/XXXX1 i386
I have 4 disks in the system. The system disk is a 2.1 Gb Seagate, and it
had 2 other 4 Gb Seagate Barracudas in it. I noticed that one of the disks
started getting MEDIA ERRORs on a regular basis, so I took a spare 4 Gb disk
out of a sister clone machine that was (at one point) identically configured
and stuck it inside. The disks are now:
Probing for devices on PCI bus 1:
ahc0 <Adaptec 3940 SCSI host adapter> rev 0 int a irq 10 on pci1:4

sd3(ahc1:1:0): Direct-Access 4095MB (8388315 512 byte sectors)
The failing disk is sd3:
[...]
sd3(ahc1:1:0): RECOVERED ERROR info:858b1 asc:10,0 Id CRC or ECC error field replaceable unit: d7 sks:80,21
sd3(ahc1:1:0): RECOVERED ERROR info:858b1 asc:10,0 Id CRC or ECC error field replaceable unit: d7 sks:80,21

sd3(ahc1:1:0): RECOVERED ERROR info:858b1 asc:10,0 Id CRC or ECC error field replaceable unit: d7 sks:80,8
(Last one happened an hour ago)
I wanted to back up the sd3 disk to the new spare disk, which is sd1. But
I can't disklabel this spare disk! I can read the disklabel off of the other
three 4 Gb disks with *no* problem ... but no go on sd1:
xxxx1# disklabel sd0 | wc -l
26
xxxx1# disklabel sd2 | wc -l
24
xxxx1# disklabel sd3 | wc -l
23
xxxx1# disklabel sd1
disklabel: ioctl DIOCGDINFO: Invalid argument
xxxx1# disklabel -r sd1
disklabel: /dev/rsd1c: Undefined error: 0
xxxx1# ls -l /dev/rsd1c
crw-r--r-- 1 root operator 13, 10 May 13 21:43 /dev/rsd1c
xxxx1# disklabel -w -r sd1 seagate15150
disklabel: /dev/rsd1c: No such file or directory
The disktab(5) entry I tried cooking up for the Barracuda is:
seagate15150|Seagate ST15150N:\
:dt=SCSI:ty=winchester:ns#78:nt#21:nc#5119:\
:pc#8384922:oc#0:
If I ktrace this last command, it shows it successfully opening /dev/rsd1c,
yet I get "No such file or directory"??? I don't get it ...
Does anyone have any idea why I can't disklabel this particular disk?
And why the O/S is pretending that /dev/rsd1c doesn't exist? It makes
no attempt to write to the disk at all, apparently ... and I don't see
any low-level SCSI driver diagnostics in /var/log/messages, either.
I'm stumped.
Thanks in advance for any suggestions. Please respond directly to me
and I'll summarize if anyone's interested.
