Disc in one of my NAS devices appears to have died of sorts. It spins up OK but the heads (I think) are making hell of a noise when the disc is being accessed and the NAS can't see it. Problem is, it's a SATA disc and I've no other device that can take SATA discs, so I can't put it into the PC and run some diags. Any tips? Should I just get a SATA PCI card and bung the thing into my PC?
