E.g., type "dmesg | less" then scroll until you see where sdb is initialized; it might show the model and serial number of the drive. Another approach is to use smartctl, i.e.: "sudo smartctl -a /dev/sdb". This will definitely show you the model and serial number. You can also use hdparm for the same effect: "sudo hdparm -I /dev/sdb". I'm sure there's more ways, but those are the first that come to mind. -Matt -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
