I just upgraded to 10.10 from 10.04 (yeah outdated, I know) and came across these errors. They show up in dmesg after I hear a click followed by a spin-down sound from my HD. I know this is usually the sound of the drive dying, but I have reason to believe otherwise because if I reinstall 10.04, the problem does not occur.

I've had similar errors using other distros with kernels more recent than 2.6.32. This makes me think it's a SATA driver error.

Thoughts?

Output from dmesg:
