Thanks. QUESTION: how do I test these devices (cdrw and dvdr drives) to ensure DMA is still enabled? I cannot figure out yet what parameters to give hdparm -I /dev/WHAT?
Wizard root # hdparm -I /dev/cdroms/cdrom0 /dev/cdroms/cdrom0 not supported by hdparm Wizard root # When SCSI emulation is not turned on I can do hdparm -I /dev/hdc, but with SCSI emulation enabled hdc and hdd don't exist.
