I've been travelling for the past month, so pardon the late tuning in here. I've *never* encountered a drive that had this problem. Controllers, yes, and those are easily dealt with in the chipset drivers. But never drives. Not since 1992 when I first took up Linux IDE stuff. I have some 7-year old IBM drives here, and they certainly don't have this problem either (but they do have working TCQ etc..). I suspect Sergei simply had a bad controller card at the time. Cheers
