Mageia forum

I have _NEC DVD_RW ND-4570A CD-DVD writer and Mageia 1.
After installation i tried to open (physically) my writer, but it was busy and not opened
I tried to

Code: Select all

eject /dev/hdc

but have no perms to do it.
I don`t know what to do wth it?
In Mandriva all was working from-the-box.
Here is fstab:

Code: Select all

In my /etc/fstab file, this is the entry for the dvd drive:

Code: Select all

/dev/cdrom /media/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0

I have no problem with the dvd drive, so I'm guessing the entry should be correct.
Maybe another user, knows better.

What does

Code: Select all

lsof -a /media/cdrom

show? Maybe you need to install lsof before that.

Otherwise i have the same fstab entry as John66, would be interesting to know what's different in your configuration.
Was it an upgrade from Mandriva or a fresh install? Another difference: Your dvd writer has a IDE(PATA) interface, mine is connected via SATA.

It was the same as yours entries for my dvd-drive in fstab. I changed it trying to solve this problem by myself.
Interesting thing:

Code: Select all

fuser -km /dev/hdc

makes "NO SIGNAL" on my monitor, that I must to reboot my computer to see smth.

Well, you immediately kill everything that is accessing /dev/hdc at that time, if your desktop environment accesses it, than it will be killed, too.

Not desktop! Monitor lost signal from videocard. That is strange.

We discussed similar problems in the German forum, seems to be a problem with UDEV.
