Weird problem with CD drive

pablowablo · 08-07-2004, 09:17 PM

When I put in a CD, I can use it fine.... but somehow Libranet won't let me eject it... I have to restart it before I can eject it... also when I try to unmount the device it says that resource is busy.... Any ideas?

btw I'm using Libranet 2.8.1

try typing "eject" (as root), that's always worked for me.

you can't unmount if you're in the directory, so first make sure you're somewhere else before issuing the command.

"The resource is busy" means that some process is pointing to the device. You have to make sure no process or program is using any file from the cd.
Here in my suse, when it was 9.0, I found out that a preloaded instance of konqueror would prevent me from unmouting cd's. So, I killed those instances and I could unmount.

eject worked! hmmm and it showed me what the problem is, only I still don't know how to fix it... It seems that my CD ROM drive won't simply eject if it is still mounted, so I have to unmount it first before it will eject by pressing the eject button.... Is this normal? Why doesn't it unmount the device when I press the eject button?

Yes it is normal. When a CD is mounted the drive is locked and the eject button does not work. Before the unmount command will work you need to close any application that is accessing the drive including file browsers and console windows (make sure the current working directory is other then the CDROM drive).

The mount command attaches the file system i.e the data on the CD to the big file tree. The unmount command well detach the files system.

ahhhh I see, so I guess I don't have any problem. It's just that my friends use my PC too and they aren't really used to Linux and I thought that they will complain about the CDROM not ejecting... But screw them.. LOL i kid... hehe thanks for the help guys

you should be able to use the chmod command to adjust the permissions of the cdrom, so that any user can umount it.
