I have some AFF800 with some X4013A that I pulled out and put in an expansion array and we have a NetApp NS224 with similar drives. We have to wipe them using one of our 3rd party erasure programs. One of the programs runs on Windows and the other program runs independently. I believe changed them back to unprotected using he boot menu option 9 and even tried some commands. I'm thinking the boot sectors might not be standard. Any other suggestions while I wait for the equipment to arrive so I can hands on would be greatly appreciated.
