Subject: Re: [2.6.30.5] Diagnosing an IDE lockup with SMART long tests

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.
