Vale probemos mas cosas:
Desconecta el disco, instala los ultimos drivers del fabricante del chipset de la placa y vuelve a poner el disco.
He encontrado esto tambien:
Open registry editor
Go to "HKEY_LOCAL_MACHINE\SYSTEMS\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}"
The Default Value should be "IDE ATA/ATAPI controllers"
Go to "0001" key if your device is on Primary IDE Chanel or "0002" if your device is on Secondary IDE channel
and change the MasterDeviceTimingModeAllowed or SlaveDeviceTimingModeAllowed to 0xffffffff depending if your device is master or slave
close registry editor.
Go to device manager select "IDE ATA/ATAPI controllers" and the corresponding IDE chanel go to "Advanced Settings" Tab and Set Transfer Mode to PIO and then to DMA if available again
That's should do it.
Chaooooooooooooooo
