Troubles wth CD-DVD Writer

[GOsha]

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

# Entry for /dev/hdb1 :
UUID=1eb2594e-0ad3-4830-ba8a-98f3fbe2900d / ext4 acl,relatime 1 1

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.

[doktor5000]

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.

[GOsha]

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.
