I think Arjan meant that's not good to tweak with harddrive's hdparm. Curiously, I can't get one of my DVD drives (/dev/hdc) to use DMA. Even when I use hdparm to set DMA, when I start reading files from the DVD, the kernel signals a reading error and performs an ATA bus reset, in fact disabling DMA. However, if I boot the kernel with ide-scsi=/dev/hdc allows me to use DMA transfers with no problems at all. Why do my DVD fails DMA transfer when used as plain IDE, but do works when used as IDE-SCSI? It's a mistery to me. Anyone? Thanks!
