OK well as unexciting as this topic seems to be... I've loaded up the drive marked as 'ARCH X330' on an old IBM server and stuck a blank compaq 18.2GB SCSI drive in the other bay, booted it up and got sg3_utils installed and issued a command to format and change the block size from 512 to 520 to see how it went, I cancelled on the 10 second countdown before the 5 second countdown appeared and something managed to mess up, got screen spam for about 20 seconds giving invalid sector data... So there you have it, DO NOT TRUST it to actually stop because it looks to have sent the SCSI commands before the countdown even began!
Anyway reissused the command and am letting it run, the seagate PDF said it'd take between 30-60 minutes for a quick/full format so I'll leave this running and see what happens.
EDIT: Interesting, after completion there were a load more kernel error messages, tried fdisk and parted on the drive, parted just exited and fdisk said there was a problem, rebooted and same problems... Going back to 512 blocks now to see if the drives had it or if 520 is too much or if the tools don't support 520 or what really.
