I don't see any media errors, so your platter and disk head seem fine. The first thing I'd do is replace your sata cables. They don't cost much and they do go bad. fyi: if you swap out drives often, you should know that a sata cable is rated for 20 insertions if I recall right. Yes, 20 not 20,000. eSata is rated for far more. In our lab we swap out drives all the time, so we routinely see sata cable failures. And in a general sense you just see weird errors like the above when they go bad.

From here on down, everything is normal / good.

Is my harddisk dying? I have two harddisks - which ones of these is it (sda or sdb)? This part of dmesg did not help me to identify which disk is ata3 and which ata4:
Just replace both cables and I bet you're fine. I always replace ours in pairs. Greg -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
