Andy,

Right here is what sun cobalt knowledgebase (http://cobalt-knowledge.sun.com) 
says about this:

(I Pasted the article because the URL is very long)

Emergency data recovery:

Q. How would I go about pulling the data from my harddrive if the server will 
no longer boot?

This procedure assumes an intermediate to advanced level knowledge of the 
linux operating system.

If the server is inaccessible, and does not boot correctly, here is an 
emergency method of retrieving the disk information.

Required: a linux/unix machine and root priveleges.


Remove the hard drive from the Cobalt machine, and hook it up in the linux 
machine. We will use /dev/hdb for examples, signifying the primary ide channel 
slave drive, and /mnt/cobalt as the mount point. Replace these with correct 
information from the system. 
Power up the linux machine, and verify that the drive was recognized. You can 
normally find which drives have been found by the kernel by typing:
dmesg | grep hd 
Once this is done, 'mount' the existing disk partitions to a place on the 
local machine. We will only need one directory for this. Which should be 
created in the '/mnt' directory. For example:
mkdir /mnt/cobalt 
After creating the directory, mount the '/' partition of the cobalt drive to 
that directory, which can be done as follows:
mount -t ext2 /dev/hdb1 /mnt/cobalt 
Then mount the remaining two partitions.
mount -t ext2 /dev/hdb3 /mnt/cobalt/var
mount -t ext2 /dev/hdb4 /mnt/cobalt/home
