Unity 500 : replace faulty disk with different disk firmware version

Hi,

I have a Unity 500 with a faulty 800GB (SAS 12Gbps) drive with firmware version S128.

Can I replace it with HGST drive (same size and speed) with firmware version C118, C250 or C368 ?

I've already tried to replace it with a HGST drive with FW Version C250, but it didn't work, and i'm not sur if it's due to FW version or another issue.

Thanks for replies
