Boot up the server with DBAN and run it for 24hrs. There is no chance in hell of your data being recovered after that then rebuild the RAID.

 

 

Thanks for that suggestion. I'm totally out of my depth when it comes to the server, so I'm best to avoid that route. Am I able to download DBAN to my Mac and wipe the drives that way? I have a USB adapter for the drives. Thanks for your help.

 

That solves the problem with the burred screws too. I'll just leave the drives in carriers for the new owner.

I guess there's 4x Seagate Constellation 2TB drives included as well now. Again, they should all be working fine. Seatools says they are. And if they're not, they're still covered by Seagate until May this year.

 

DBAN will wipe anything connected to the computer - it is a bootable disk (download, put onto flash drive, boot) so if you get the server booted up from the image and run "autonuke" it'll erase everything - http://www.dban.org/

With OSX there is an option in Disk Utility under "Advanced" to do a few passes over the disks. It'll take forever with a USB caddy so my suggestion of just booting up the server is the best bet.
