Hi!
Ok, that means Andre's patch works. Congrats, Andre! Now, could you send me 'hdparm -i /dev/hdb' for the ZIP? It seems to be in SWDMA0 mode, which is interesting, because I thought it can't do that. You probably have some newer model.
Do all your drives work correctly now?
Thanks for your effort, Vojtech
