Also, the benchmark facility with HDTune reveals that the burst speed of the drive is 2MB - consistent with the hdparm -t speed when ide-generic is used. Strangely enough, I've gone into Device Manager, and the transfer mode Windows claims it is using is PIO, which seems to be contradictory to what HDTune is telling me (and leads me to ask another question, I've included in my reply to Alan) I've also tried to various registry settings to try and force the device into UDMA or PIO, to no success - as far as I can tell MWDMA may well be the lowest speed Windows XP supports operating devices at?
