If anyone could give me advice on this I would be most grateful. I have two DVD drives on my PC (2.4 Duo Intel + Nvidia), a DVDRW which is the master & a DVDROM which is the slave. They are connected via IDE ribbon cable to the single IDE slot on the motherboard. However the devices are set to PIO mode in device management, thus causing my entire system to slow up when accessing a CD. To make matters worse the drives do not even recognise DVD's and treats them as CD's. I can't burn anything to DVD as my devices are in PIO, as Nero 7 smugly informs me. I have tried all the methods i could find on the net to reset the drives to DMA. That includes opening regedit and resetting the 'bad burn' counter, uninstalling all the dvd drivers and re-installing them. Uninstalling all the IDE channels and letting XP reinstall them. I've checked the cabling and pin heads at the back of the Drives. Nothing seems to work. Would buying an IDE converter and switching the drives to SATA cabling work? My harddrive is SATA and i have five spare SATA ports. If not any other ideas? The DVDRW is a Lite-on LH-20A1H.
