|There have been plenty of posts on this subject, both on stable and
|hardware. 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?
Randall
