I don't have other drives of the same model, but 3 ones slightly smaller
in size and previous generation, those are just a few months older (but
also have way more uptime), see below for the smartctl output. I've never
seen ATA errors on them.
These other drives are running on AMD based platform, SB600 SATA with AHCI.
Just for the record, on the VIA there were no errors yet with
2.6.27-rc6-git3 though I ran some compiling on it. As such it *could* be
that one of the patches pushed by Jeff helped:
[libata] LBA28/LBA48 off-by-one bug in ata.h
sata_inic162x: enable LED blinking
ata: duplicate variable sparse warning
