Which file system for storage hard drive?

Oh well. It turns out I have a defective drive. Of course it only became obvious after it was too late to take it back (within a week) and I have no receipt.

It’s a Hitachi and they have a good return policy, but I’ve got to send it to Singapore (although they might well pay for that).

What a pain in the ARSSSSSSSSSSSSSSSSSSSSEEEEEEEEEE.
