Comment 100 for bug 550559

The problem occured to me again, this time on a different setup: dual boot Windows 7 and Kubuntu 11.10 Oneiric Ocelot, so a completely different kernel than Lucid. Ran Windows 7 exclusively for a week: no apparent problems with the disk. My 2nd day with Kubuntu and after some 5 hours of uptime... boom.

I agree with #96: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550559/comments/96 It seems to have nothing to do with the physical state of the disk or cables. Well maybe in some cases it might have been the cause but certainly not always. It's also not distro related and seems to happen on many kernel versions so I guess it's a kernel thing that persists under the radar. The combination of the Linux kernel and some type of (SATA) HDD controllers. In 2 years of Vista I never had problems with the HDD in different versions of *buntu it has been bugging me. Performed the SMART test several times and each time it reported that the HDD was healthy.
