Re: dying scsi drive?

Append root=/dev/sda1 to your boot command in /etc/aboot.conf.  (I
assume you're using aboot not milo?)

Did you partition this disk or format /dev/sda without any partitions?
The lack of a partition table might cause this problem.  Why do you have
the message "Unable to read /dev/sda"?  It should always be sda1 or

If sector 0 truly is bad, this drive may be unusable.  Many modern
drives however keep an internal bad blocks list and will reallocate a
block from their spares when one goes bad.  Play around with the
smartctl program in the debian package smartsuite, and try 'badblocks -n
/dev/sda' after booting off a cd-rom (/dev/sda? must not be mounted).

Now I've been trying to install the box with debian, but I've run into problems with my scsi drive (seagate medalist st34520n). I installed debian once and all went seemingly fine, but when I tried to boot the freshly installed base system kernel paniced because it could not read the partition table of the drive (that had the root partition). The error message was something like:
