I've had similar problems myself from 4.2-R on, but only because I didn't have any ATA66+ hardware until after I was using at least 4.2-R everywhere. As long as the drive itself isn't a problem, switching controller/cable combinations has always removed the problem. It seems that heterogenous ATA66+ configurations with lots of drives is a crap-shoot at best. Have you tried swaping the cable out with a premium non-rounded ATA/100 cable (the kind you buy seperately for $20+ each)?
