accully ive messed with jumper settings and it seemed to work great ever since then.., i was at the point where both my drives woundlt boot.. but just switched them from master to slave and the worked fine since.. i dunno whats up with them, and i dont think it has anything to do with beta 11, becuase i got the same problem with 1.03, and when i was doing it i couldnt even upgrade the drives
