CD-ROM: Inappropriate ioctl for device

Postby Axel Larator » Sun Jun 17, 2012 7:03 am

Hello Everybody,

since yesterday my CD-Roms are gone. Neither the build-in nor an USB one is working. Or better they are recognized but not mounted. The only error message popped up with eject. eject: unable to eject, last error: Inappropriate ioctl for device

Where do I look for an Inappropriate ioctl ? lsub and lspci are finding both drives. Both are working in terms of spinning (and reading) and had been used for the Mate installations.

hdparm -D1 /dev/cdrom gets me this:

setting drive defect management to 1
HDIO_DRIVE_CMD(defectmgmt) failed: Input/output error

hdinfo delivers:

What are they listed as in /etc/fstab ? In terminal ...

Code: Select all

cat /etc/fstab

Can't say if it's related to your issue. Recently found out "eject -T" wouldn't work w the dvd or cd drives on this pc anymore. Fix turned out to be as simple as changing the entries in fstab for them from /dev/scd0 to /dev/sr0 for the dvd-rw and the cd-rom from /dev/scd1 to /dev/sr1 Guess can't hurt to look @.
