Have you tried the drives behind a SAS expander?So, has anyone managed to get those SUN-branded HUSMM1640s to work? I've got 4 and not a single one is recognized in my usual Supermicro X9 board with 2308 IT-flashed controller. I don't buy disks often so I might be missing something here. As far as I remember, even disks formatted to 520/528B would still be recognized by the controller - they just wouldn't show up in most operating systems (until they're formatted to 512B). But mine are not even detected by the controller, and sg_scan -i in CentOS doesn't show any of them either. It's quite unlikely that I'd get 4 out 4 DOA, so it's probably some incompatibility issue?
