If you use a single sided drive its compatable with RX01/02 and can read and write them. If you have a two sided drive its still compatable but media generated in two sided mode will be incompatable with RX01/02. That simple. The yabut is you must have the Plessy driver for it as the stock DX/DY knows nothing of the two sided modes.. And any two or single sided drive will only be used single sided. Allison
