DVD drive wont eject.

Hi all, after umounting my dvd drive and then trying "eject" i get

Code:

unable to eject, last error: Invalid argument

And i have to reboot to get it out

Does anyone know whats wrong?

If you have unmounted the dvd (you cannot mount or unmount a "drive", strictly speaking it is the fs on the dvd you are un/mounting) there should no longer be a corresponding icon on the desktop. Naturally, the eject option you get from rt-clicking on such a thing will contain an invalid argument - probably the umount command.

Try ejecting the dvd while it is still mounted. If this still dosn't work - try it with cdrecord in cli - and post the entire output. (cdrecord --eject should open the drawer of the default device when it's content is not mounted.)

Thanks for the reply, when i try the eject command while the CD is still mounted (its a DVD drive but im currently using CDs, dont know if thats important) i get the same

Code:

eject: unable to eject, last error: Invalid argument

I got it out, put the cd back in then tried "cdrecord --eject" and got

Code:

cdrecord: No CD/DVD-Recorder device specified.
Usage: cdrecord [options] track1...trackn

so i tried "cdrecord /dev/dvd --eject" and "cdrecord /dev/cdrom --eject" got

Code:

cdrecord: No write mode specified.
cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.
cdrecord: Continuing in 5 seconds...
cdrecord: Badly placed option. Global options must be before any track.

Then i tried "cdrecord --eject /dev/dvd" and "cdrecord --eject /dev/cdrom" and got:

Code:

cdrecord: No write mode specified.
cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.
cdrecord: Continuing in 5 seconds...
cdrecord: No CD/DVD-Recorder device specified.

Dont know where to go from here

EDIT: Just had a look at dmesg and saw a few

Code:

program eject is using a deprecated SCSI ioctl, please convert it to SG_IO

Not too sure what it means though.

... I don't think this will actually stop it.

cdrecord --scanbus
... to see valid targets. Devices have form: "device:target,lun" - is it possible you have more than one cd/dvd drive? So you need to specify the target to distinguish them?

cdrecord dev=0,0 --eject or cdrecord dev=1,0 --eject

There is an additional hoop to jump through if this is a atapi drive and ide-scsi is not enabled.

Of course, "eject -v /dev/hdc" on cli should also tell you something.

See the man pages for cdrecord and eject for details.

I _think_ i fixed it by uninstalling xcdroast. It seems to be ok now. Thank you.

weird - so xcdroast was hogging the device perhaps? Normally you just get "device busy". I'll leave this one for others. Well done.
