I have same problems for a long time (you can found my posts in this
list last year). From my point of view - this is HW problem. For
example: I have 4 same machines Sun Fire X2100 and one of them have this
problem (always on same ATA channel), others not.
HW becomes cheapper and cheapper at cost of lower quality.
