SH- S202J Ultra DMA Mode4 OR Ultra DMA Mode2

My new SH- S202J is detected just as Ultra DMA Mode2 instead of the advertised Ultra DMA Mode4. Any Idea? It shares the cable with a CD reader that is Ultra DMA Mode2, could that be the problem? because in the other cable I have PIO and UDMA and they work normally


for UDMA4 operation, you need a 80wired cable (connectors are colour coded). It is also a good idea to install the drive as master at the end of the cable then.


The cable is ok, I use it with my Hard Drive and works UDMA Mode5.
The DVD Writer is installed as master in the secondary IDE channel.
