Not all IBM DTLA drives are bad; actually, they are not bad at all (because all bad are already dead :) DTLA-5 drives (5400rpm) do not support tagged queueing, unlike DTLA-7 (7200rpm). They offer good performance considering spindle speed and 512K of cache (in fact, 380K; firmware takes the rest). About "new drive" and "its slowness", what did you expect from 2-year old drive featuring 20Gb per plate? --- Regards, Rhett Dag-Erling Smørgrav wrote: > > "Kevin Oberman" <oberman@es.net> writes: > > I have a P3 system running STABLE built on March 7.
