I have a Buslogic BT-958 with a 4.5G Quantum Atlass II on the "wide" connector,
and a 1G Seagate ST31230N, a Toshiba CDROM, and an IOMEGA ZIP drive on the
narrow chain.
The partitions are set up as follows:
/dev/sda (Seagate ST31230N): 64 heads, 32 sectors, 1010 cylinders
Units = cylinders of 2048 * 512 bytes
Device Boot Begin Start End Blocks Id System
/dev/sda1 * 1 1 300 307184 6 DOS 16-bit >=32M
/dev/sda2 301 301 364 65536 83 Linux native
/dev/sda3 365 365 1010 661504 6 DOS 16-bit >=32M
/dev/sdb (Quantum Atlas II): 64 heads, 32 sectors, 4341 cylinders
Units = cylinders of 2048 * 512 bytes
Device Boot Begin Start End Blocks Id System
/dev/sdb1 1 1 800 819184 6 DOS 16-bit >=32M
/dev/sdb2 801 801 864 65536 83 Linux native
/dev/sdb3 865 865 928 65536 82 Linux swap
/dev/sdb4 929 929 4341 3494912 5 Extended
/dev/sdb5 929 929 992 65520 83 Linux native
/dev/sdb6 993 993 1792 819184 83 Linux native
/dev/sdb7 1024 1793 2192 409584 83 Linux native
/dev/sdb8 2048 2193 3192 1023984 83 Linux native
/dev/sdb9 3072 3193 4341 1176560 83 Linux native
Now, here's how everything works: /dev/sda1 is my boot paritition and also
has DOS on it. /dev/sda2 was going to be a backup root partition that I
could use in case I lost my normal root partition on /dev/sdb2. I also
boot Linux from /dev/sda2 using the NT boot-loader. /dev/sdb3 is currently
unused. /dev/sdb1 is my NT partition, /dev/sdb2 is my Linux root, and the
rest of /dev/sdb are Linux partitions.
NTLDR is on /dev/sda1 and has a menu that includes DOS (/dev/sda1), NT
(/dev/sdb2), and Linux (/dev/sda2). All this works. But I want to
use the /dev/sda3 partition as a storage partition (formatted as msdos,
used as VFAT) to store both Windows and Linux stuff. But everytime I
mount the partition and try to read or write to it, this is what I get:
Dec 9 18:42:16 xenon kernel: scsi : aborting command due to timeout : pid 1543703, scsi0, channel 0, id 0, lun 0 Write (6) 1a bc 39 f4 00

this is repeated for awhile, and then
Dec 9 18:42:17 xenon kernel: SCSI host 0 abort (pid 1543703) timed out - resetting
Dec 9 18:42:17 xenon kernel: SCSI bus is being reset for host 0 channel 0.
Dec 9 18:42:17 xenon kernel: scsi0: Sending Bus Device Reset CCB #1543734 to Target 0
Dec 9 18:42:17 xenon kernel: SCSI host 0 abort (pid 1543704) timed out - resetting
Dec 9 18:42:17 xenon kernel: SCSI bus is being reset for host 0 channel 0.
Dec 9 18:42:17 xenon kernel: scsi0: Unable to Reset Command to Target 0 - Reset
Pending
Dec 9 18:42:17 xenon kernel: SCSI host 0 abort (pid 1543707) timed out - resetting
we do this for awhile, and finnaly
Dec 9 18:42:18 xenon kernel: scsi0: Resetting BusLogic BT-958 due to Target 0
Dec 9 18:42:18 xenon kernel: scsi0: *** BusLogic BT-958 Initialized Successfully ***
It works for awhile, and then
Dec 9 18:42:38 xenon kernel: scsi : aborting command due to timeout : pid 1543728, scsi0, channel 0, id 0, lun 0 Write (6) 1a c2 09 f4 00
Dec 9 18:42:38 xenon kernel: scsi0: Aborting CCB #1543761 to Target 0
Dec 9 18:42:38 xenon kernel: scsi : aborting command due to timeout : pid 1543729, scsi0, channel 0, id 0, lun 0 Write (6) 1a c2 fd f4 00
Dec 9 18:42:38 xenon kernel: scsi0: Aborting CCB #1543762 to Target 0
and it all starts over again.
What's the deal?
