Comment 4 for bug 36664

I confirm that here.

My DVD burner/reader doesn't have dma activated, as it should have. "Should have" in the meaning that a standard (let's say "lambda") user should not have to do any line of command (nore config file edit) for having full functionality with disks and readers.

----------------------------------------
$ sudo hdparm /dev/hdc

/dev/hdc:
 IO_support = 0 (default 16-bit)
 unmaskirq = 0 (off)
 using_dma = 0 (off)
 keepsettings = 0 (off)
 readonly = 0 (off)
 readahead = 256 (on)
 HDIO_GETGEO failed: Invalid argument
