Hello,

I'm sure that this is a simple problem, but I can't seem to find an answer that works for me.

I can't seem to eject CD's.

The problem:

Code:

$ eject /dev/scd0

eject: unable to eject, last error: Inappropriate ioctl for device

Code:

$ sudo eject /dev/scd0

eject: unable to eject, last error: Inappropriate ioctl for device

When using sudo eject, i still get the device error, but the CD ejects anyways.

I have had this problem before... but I fixed it by mounting/unmounting the CD-Rom. Not sure why that worked, but it doesn't this time.

Any Ideas? I'd rather not have to sudo eject every time i want my cds back.

Solutions I've seen around various forums:
-Am I a member of group "cdrom" -yes.
-Are the permissions set correctly? -yes. i even did a chmod 777 /dev/scd0

Thanks.

Run

Code:

eject -v /dev/scd0

and see if you get any more information. Check /var/log/messages as well.

Code:

$ eject -v /dev/scd0

eject: device name is `/dev/scd0'

eject: expanded name is `/dev/scd0'

eject: `/dev/scd0' is mounted at `/media/cdrom0'

eject: unmounting `/dev/scd0'

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 failed

eject: trying to eject `/dev/scd0' using floppy eject command

eject: floppy eject command failed

eject: trying to eject `/dev/scd0' using tape offline command

eject: tape offline command failed

eject: unable to eject, last error: Inappropriate ioctl for device

Calling that with a "sudo" in front of it lists out the same thing, but it stalls at "...using SCSI commands" and then ejects, and says "SCSI eject failed"

Thanks.

Shouldn't that be

Code:

eject /media/cdrom0

I'll be interested to see if that works. The manpage explicitly says:

Code:

The  device  corresponding  to  <name>  is  ejected. The name can be a device file or mount point, either a full path  or  with  the  leading "/dev",  "/media"  or  "/mnt"  omitted.  If  no name is specified, the default name "cdrom" is used.

But of course, maybe that's not quite right.

Original poster: Was there any information in /var/log/messages? It's odd that root is succeeding here where you do not.

calling eject /media/cdrom0 just gives the same errors, because they reference the same thing.

What i find exceptionally weird is that root ejects the CD, but still echoes the errors. What could cause that?

Not entirely sure what all of that means.

Note:

ejecting with sudo produces this in the message log:

No errors, but still deprecated SCSI ioctl.
