Quoting Robert Hancock: : Is it always this drive that's failing? I see there's a second of the : same model, does it show the same behavior? : : > ata1.00: ATA-6: HDS722512VLAT80, V33OA60A, max UDMA/100 : > ata1.00: 241254720 sectors, multi 16: LBA48 : : If only that particular drive shows this problem, then I would start : to suspect a hardware fault with that drive. The fact that it fails : with both IDE and libata (and with ata_piix, which is a really : commonly used and tested libata driver) rather points in that : direction. That was a very good diagnosis. I switched my two Hitachi drives for Maxtors, and the problem went away. I was able to do a SMART long test on all my drives without lockups and without any kernel complaints on the console. Thanks a lot, I had no idea these Hitachi drives had a bad firmware. Looking at the tags on the drives, they were manufactured late 2003 and early 2004.
