natilus cdrecord
 

I am alittle lost on this one.

I tried to burn a data cd with natilus and it came back with this error.

when I logged into the system as root, it allowed me to make my copy. I changed the permissions on cdrecord, logged back into "user account" and returned the same error again.

extra info:
I appended my lilo.conf with
append="hdc=ide-scsi"

fstab reads as such

what am I missing?
Any help would be great

Change the permissions to your /dev entry of the cd-rw or add your user to the corresponding group (i think it was cdrom)
try: ls -l hdc && ls -l sg0

I suggest you install k3b. I hate QT apps. I REALLY hate QT apps. And I still think k3b is utterly amazing. I use it for all my cd/dvd burning tasks.

I tried the link and it returned an error message:
/usr/bin/ls: hdc: No such file or directory

I did the install of k3b.
it works under root logon, burned a cdr no problem. logged on as "user" & k3b returned this error.

Found media: CD-R (Empty)
Please insert a complete or appendable medium (CD-R(W)) into drive

SONY CD-RW CRX320E
(/dev/sr0)

Why is k3b calling out a sr0 and natilus is calling our sg0?

I am guessing that this is some "rights" or "permissions" thing, why else would I be able to perform the tasks under root..

an older post
Does this sound right?



I am not keen on changing permissions, would this be correct?
chmod go+rw /dev/sg0

Update:
ran chmod on sg0, I tried to burn an audio cd with k3b as user. Worked! I will have to assume that this will work for data as well.

Yes that should do the trick. :)

k3b also has a graphical permissions configuration. It should just ask you for the root password when you attempt to edit it. In Debian, right after you install k3b is nags you about fixing permissions until you do. :)

I tried that and it didn't work. k3b stopped nagging me about permissions and nothing. When I changed sg0's permissions is when I was able to burn as user.

It's working now and that was the most important
