Defects tend to happen to all the units in a certain production run. If one goes, the others may go before you can replace & rebuild the first bad drive. Fair enough. I'd still prefer to have all my RAID drives be the same manufacturer + model. Maybe that's just an ingrained habit I picked up

For SATA, you need to add "-d ata" to the command line, i.e.: # smartctl -d ata -a /dev/sda bungo:~# smartctl -d ata /dev/sda smartctl version 5.36 [i686-pc-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ bungo:~# smartctl -d ata /dev/sdb smartctl

There was/is an issue with certain Maxtor SATA hard disk drives. In some cases, it is necessary to force them to SATA-I mode (1.5 gb/s). There's a jumper in the back for that. Yep, set that :-) 4 x Maxtor 250GB SATA drives (Incidentally I would recommend against making a RAID array from seve
