Cannot eject CDROM

dictum9 — Fri, 06 Jul 2007 10:07:23 GMT

I have a 11.23 on zx6000 and I cannot eject the cdrom, when I push the button, the drive doesn't open.

The cdrom is not mounted, there is nothing under /cdrom or /SD_CDROM.

What can I do?

Shalom,

fuser -cuk /cdrom
fuser -cuk /SD_CDROM

Retry eject.

It that does not work:

ioscan -fnC disk

See if your DVD is dead.

If possible boot and press button after restart.

If that fails call HP hardware you probably need a new one.

When you say "there is nothing under /cdrom", did you do an "ls /cdrom" or run bdf to see if the CD was mounted?

You could simply have a bad CD drive. You may want to use the paperclip-in-the-hole trick (push a straightened out paperclip into the little eject hole in the front of the CD drive).

Hi,

do fuser also with your device path, i.e. /dev/dsk/cxtydz - the right cxtydz you get from your ioscan SEP mentioned above.
If no processes are running at your cdrom - there's normally a little hole under the tray, use a paper clip and release the tray.

fuser is fairly crippled at finding user that have the CDROM mountpoint open and the CDROM driver disables the eject button whenever the device is open. The most common error is to cd into the CDROM mountpoint. The directory is open but fuser doesn't see that condition. The only reliable way to see the processes that have the CDROM open is to download and run lsof.

Now you can always use the paper clip method to mechanically force the CDROM door open, the process(es) that are using the CD will likely crash.
