I'll check my machine at home tonight, but I usually get 4.5-4.7MB/s to my Empire 2100 for writes from my 2842. I would expect the Hawk to do at least 3-4MB/s. >I'll go try re-enabling tagged queuing and see if that helps, >although I've been having problems with that corrupting disks. Perhaps some component in your system is dying? A VL video card perhaps? Do you see any difference in performacne when you're not running X? >-- >Mike Pritchard >mpp@minn.net >"Go that way.
