You may try using atacontrol to force the "slave" to UDMA100 as well. Also, at 11MB/s, its above the rate I'd expect to see if it was using PIO (Though, I may easily be wrong on that). Also, if you're copying from the disk, to the same disk, keep in mind, 11MB/s apparent, is 22MB/s of disc I/O. What kind of CPU usage do you see during the copy? (time, uptime, and vmstat output would be helpful) --- Harrison Grundy
