If you used mount, then you'll probably have mounted the CD fs at /media/cdrom0
(navigate the fs tree from cli)
you can also explicitly specify a mount location...
sudo mount -t iso9660 /dev/sr0 /media/cdrom
you are correct to test with data cds.
- invalid option --v
usage: [t] [DEVICE]
curious... -v is for verbose output. -t is for closing
~$ eject -v
eject: using default device `cdrom'
eject: device name is `cdrom'
eject: expanded name is `/dev/cdrom'
eject: `/dev/cdrom' is a link to `/dev/scd0'
eject: `/dev/scd0' is not mounted
eject: `/dev/scd0' is not a mount point
eject: `/dev/scd0' is not a multipartition device
eject: trying to eject `/dev/scd0' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: trying to eject `/dev/scd0' using SCSI commands
eject: SCSI eject succeeded
the eject failure is often a precursor to HW failure. Have you tried this drive in another OS recently?
I don't think DSL comes with many manual pages - see
your version is not behaving according to standard
you can also try
(you'll probably have to specify a device /dev/sr0 - read the wodim manpage to learn more than you'd ever care to about cd roms).
What I'm trying to do here is interact with the cdrom drive itself.
The approaches are suggested by the dmesg output -
"unable to open cdrom drive" --> try eject in verbose
"sr0 CDROM (loctl) reports illegal request" --> no disk in the drive, disk is blank, disk is corrupt, disk is not recognised format (see below).
"unable to identify cd-rom format" --> make sure it is an unencrypted, uncompressed data cd (not the DSL install/live cd.)
Looking at your machine:
... this is remarkably full featured for it's time, that's actually quite a good find. I can see why you went the DSL route. You can rule out a faulty install by trying another small OS.
Lenovo report that your drive is automatically /dev/sr0
I don't think DSL automounts removable media.
You never did say what it was that gave you the impression the drive is not seen.
