We appreciate all the response.  Consensus is:  the disk from the 
SunBlade 150 WILL work, that any regular ata/ide disk will work; disk 
replacement will be a standard procedure.

Our system was mirrored across primary and secondary disks; the 
secondary disk is carrying the load now.  We are not facing a re-install 
- just need to remirror with disksuite once the bad disk is replaced.

The initial problem was the primary disk lost its label.   We got 
"corrupt label - bad geometry" on a routine reboot.  We were able to 
boot from the secondary disk.   (phew!)

We ran format to repair the label and found the primary disk no longer 
matched the secondary?  Very curious...or is this to be expected?  It 
had 65529 cylinders compared to 19156 on the secondary; 31.5 GB compared 
to 37.27 GB on the secondary.  We were able to partition it and label it 
using the new smaller size; fsck of raw partitions failed until a 
filesystem was built on them - then fsck succeeded.  We are unable to 
duplicate the original partition table.  This is what happens:

Warning: error writing VTOC.

Have you ever seen anything like this?  Is this disk salvageable?

Thanks for your help...will summarize for the list again with any new
