IIRC none of them were bad disks. | |Randall, |1) post a copy of dmesg so we can see what hardware you have. |2) measure the cable - M/B to drive. Just replaced the 18" ATA66 cable with a new 20" ATA66 cable. No CRC errors yet but I'll keep an eye out for more, and do a mfgr drive-test run just to be safe. I've attached a dmesg. This is an ASUS A7M266 MB with two UltraDMA 100 hard disks on the primary controller: a Maxtor DiamondMax 60 60GB master, and an IBM Desktar 60GXP 60GB slave. The Maxtor is the new one, and the one that had the CRC errors. On a related note, I'd read that if you have two IDE hard disks on an ATA66 cable, the master always goes in the middle (and if only one, it goes at the end). However, this Intracom ATA66 cable has the end connector unconditionally labeled Master(0) and the middle connector labeled Slave(1). Are these guys confused, ...or am I?
