I get basically nothing.
IO_support = 0 (default)
HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
HDIO_GET_DMA failed: Inappropriate ioctl for device
HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Inappropriate ioctl for device
I don't know what an "ioctl" is either.
Tried it with a disk in the drive and not in. Same results either way.
Looking in /dev I see cdrom2, cdrom3, cdrw2, cdrw3, dvd2, dvd3, dvdrw2
listed. I have one (1) cd/dvd combo drive and one (1) dvdrw drive.
Mostly I use the dvdrw.
I'm wondering if there's an issue of system resources. Playing a disc in
my laptop [ 8.04/3.5.9 - 1.8GHz 4gig ] the hard drive and DVD lights
just flicker every once in a while. Same on my winders box. BUT, in my
main computer [ 8.04/3.5.9 - 3GHz 2gig ] the hard drive light in on
continuous as well as the DVD light.
Life is what happens while your busy making other plans.
