11	Is your DVD units SCSI, if so you will not be able to use hdparm to set
12	any options. hdparm doesn't work with SCSI unit, you can list the
13	parameters but not set them.

15	My BenQ DW1620 is an IDE unit connected to hdd so I should be able to
16	set the parameters using "hdaprm". I can set some parameters but not
17	DMA with "-d1"
