Nach dem anwenden deiner Parameter hat sich leider nichts verbessert:

/dev/hda:

Was sollten denn "-c3 -u1" bringen? Von 16 -> 32 Bit I/O-Bus (soweit ich
den Parameter "-c" verstanden habe) erwarte ich zwar viel, aber
irgendwie hat sich nichts verbessert.
Die Platte ist eine 2 Jahre alte Seagate 80GB, auf einem ASUS A7A266
Motherboard (3 Jahre alt). Soweit ich mich entsinne unterstützen beide
nur UDMA100. Kann man die evtl. noch etwas weiter verbessern?
Grüsse!
