Linux and bad SCSI HD: can I force mount a partition?
RS
I have this SCSI HD which developed a problem. It seems that
sector 0 of the HD turned bad.
When my Redhat Linux 7.3 boot up, I got this message:
--
sym53c896-0-<4,*>: FAST-40 WIDE SCSI 80.0 MB/s (25.0 ns, offset 31)
SCSI device sdc: 71776260 512-byte hdwr sectors (36749 MB)
sdc:SCSI disk error : host 0 channel 0 id 4 lun 0 return code = 2
I/O error: dev 08:20, sector 0
--
It cannot mount /dev/sdc5. But when I do '/sbin/fdisk -l',
I see the partition there:
--
Disk /dev/sdc: 255 heads, 63 sectors, 4467 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 2 4467 35873145 f Win95 Ext'd (LBA)
/dev/sdc5 2 4467 35873113+ 83 Linux

I verified the disk through the SCSI bios. It also reported sector 0
is bad. I tried to reallocate it but failed.
Is there a way to force Linux to mount the partition?
Thanks in advance,
Roger

Copy the whole hd to another disk or an ftp server. This makes sure that
another disk failure won't destroy any more data. If you know the exact
start/end of the partition, you can mount it using something like this:
losetup -o start_position_in_bytes /dev/loopX image
mount /dev/loopX /mnt
