Comment 6 for bug 114122

I'm also having this problem since I upgraded to 7.04. No problems previously nor in Windows even now.
In the forum some people report that the problem solved after the last kernel update but that's not my case. I've also tried a different kernel (i386 instead of generic, ie x86x64 in my case) without joy.

hdparm /dev/hdc:
