i'v got my nec3520a (master) and the samsung h352a (slave) on the secondary ide Channel, and both of them are in ultra dma mode 2 (i used the device manager).
When a dvd is inserted in the samsung, nero drive speed tells me:
read speed (combo box)=maximum , Current : x0, and there is no choice in the combo.. Spin down time = 4min... Seems something is screwed, i think i'll try to reflash the firmware (maybe with the rpc1). But for that i'll need to install a floppy disk.
(i used the official (?i hope ?) samsung LiveUpdate10_Eng_Install.exe, which searched for an update on the net before)
