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. > 4 x Maxtor 250GB SATA drives (Incidentally I would recommend against making a RAID array from several drives from the same manufacturer. Especially if they're the same model. Even more so if they're the same batch.) -- André Majorel <http://www.teaser.fr/~amajorel/> Discriminating spammers prefer bugs.debian.org. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
