Hard drive speed weird

[Nach]

I went on vacation for a bit, when I came back, for reasons unknown to me, turning on my computer, one HD is now having very slow reads.

dmesg keeps repeating this message during HD reads:

Could it be an issue with a new Linux Kernel?
Or did the cable die on me? Motherboard acting up on that SATA port? Hard drive decided to start dying while I was away?

Anyway I can do further diagnostics to pinpoint the problem?

Thanks.

I'd check the cable and the kernel. easiest thing to check really. grab a SMART reader and see what that says.

Nothing looks problematic.

SeaTools is effective. Grab the DOS version (it's a standalone, self-booting utility).

I imagine this never occured since the initial setup of said computer with that harddrive, so I doubt it is an issue with the Linux Kernel. Move the hardrive to another computer or try a different cable and see if the problem persits. You may want to first run SpinRite and backup your harddrive b4 you start experimenting. I had a harddrive that began acting strangely and it died on me b4 I could back anything up.

As I started up, it upgraded to Linux 2.6.26, which is new, and not the initial setup.

A quick google of SATA and 2.6.26 comes up with threads about it being broken... a lot of the threads seem to refer to a G5 (Mac), but it's still Linux and it's doubtful a standard would have changed between platforms...
