Yes, I noticed that! The gui was using the file cdrom, which was just a link to cdrom0, which was just a link to /dev/hda. I have a physical cdrom drive, so I'm pretty sure pointing to hda isn't correct. I found a source on the net about mounting drives, which said the generic mounting point for CDROM is /mnt/cdrom, but there was no folder with that name in my mnt folder. I created one... but I don't know how to proceed from here.
I did what you said, first typed "dmesg | grep -i cdrom" and got:
SJCD: Sanyo CDR-H94A cdrom driver version 1.7.
SJCD: Sanyo CDR-H94A cdrom driver version 1.7.
SJCD: Sanyo CDR-H94A cdrom driver version 1.7.
cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
SJCD: Sanyo CDR-H94A cdrom driver version 1.7.
When I just typed "dmesg", I saw lots and lots of messages about /dev/hda and errors:
ATAPI device hda:
Error: Not ready -- (Sense key=0x02)
Media load or eject failed -- (asc=0x53, ascq=0x00)
The failed "Test Unit Ready" packet command was:
"00 00 00 00 00 00 00 00 00 00 00 00 "
Thanks for the quick reply, I look forward to your further help!
