reg. key :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0001 or 0002 (depending on beeing primary[0001] or secondary[0002] ide channel)
there you modify the DWORD value of :
if the drive is on master: "MasterDeviceTimingModeAllowed" or
if the drive is on slave: "SlaveDeviceTimingModeAllowed"
to ffffffff
then go back to your device manager set your drive in IDE channel properties first back to pio and then, after confirming, again to dma ...that should do the trick
