Hi, I have a system with raid10 running Ubuntu 8.10. It uses a "promise"card # lsusb .. 01:02.0 Mass storage controller: Promise Technology, Inc. PDC40718 (SATA 300 TX4) (rev 02) .. I have 4 identical disks on it and they show up as /dev/sda, b, c, and d. However, sdb needs to be replaced. How can I tell which drive is sdb? Is there a way to identify what drive is what?
