Are my drives dead?

I've recently bought a refurb Poweredge R710. It has a Perc 6/i controller and it came with 4 x SAS HDDs. They are Hitachi HUS156060VLS600 (which as far as I'm aware, are Dell certified drives?).

Now the BIOS, Diagnostics, and Nautilus firmware updater all recognise the drives fine (and according to Nautilus, they all had the latest firmware on), and so does the Perc 6/I controller. They all show as 'Ready' until I add them to a RAID configuration. Then, they all show 'Failed'. I can't initialise them then as soon as I restart the configuration throws up errors.

Is there anything I can do?

EDIT: By the time this post got approved, problem is solved. Drives had NetApp firmware on them which is incompatible with Perc. Drives swapped with supplier, no problems.
