Just another "me too". I've seen (S)ATA-related problems on 6.x (mostly 
6.0) based machines, in some cases these appear to have been physical 
drive errors,  but I haven't been able to verify each individual case. I 
don't know if quality control is sorely lacking on newer SATA drives or 
if it's something else... it has caused me to question whether or not 
there might be a driver/OS level issue...
