Hi all I'm using 2.C8 but I dont' think it matters.
Why does DVDInfoPro show the Drive Interface is ATAPI-3? Shouldn't it be ATAPI-4???
ATA/ATAPI-3 is DMA2 (not UDMA2) which has a max transfer rate of 16Mb only!!!
ATA/ATAPI-4 is UDMA2 and is at 33Mb!
After weeks of experiment, I am 99% sure this is what is tricking my enclosure to function at 16Mb max transfer rate! I have mentioned before using the same enclosure I can get 33Mb with a Seagate HD, but not with the NEC 3500.
For ATA/PIO/DMA/UDMA ref see here
