[QUOTE=alan1476;2123857]You were dreaming, the BenQDW1655 will not run at UDMA 4 with any firmware. The BenQDW1640 will but not the DW1655. Sorry to be the bearer of bad news.;)[/QUOTE]
Thanks, alan1476. I promise not to shoot the messenger, but the person who wrote the BenQ product sheet better not cross my path;). Seriously, though, I’m having a hard time reconciling the product sheet, which says that the BenQ DW1655 can operate at Ultra DMA 66/100, with your response and everything everything else I have read today that the DW1655 cannot exceed UDMA Mode 2. Is the product sheet just wrong, or is there something (besides flashing the firmware) that can be done to boost the speed to UDMA Mode 4?
