Comment 26 for bug 75753

I'm running Hardy (upgraded from Gutsy) here and notice a similar problem:

My DVD-writer suddenly had the following permissions:

   brw-r----- 1 root disk 3, 0 2008-01-10 09:37 /dev/hda

There are 2 problems with this:
1) It should be the group "cdrom" and not "disk"
2) Since it's a CD/DVD writer, the permissions should be 660 and not 640. :(

After changing it to:

    brw-rw---- 1 root cdrom 3, 0 2008-01-10 09:37 /dev/hda

Things seem fine again.
If there's already some documentation regarding how to change files in /etc/udev/rules.d/ in order to fix this reboot safe, I would be happy if someone could point me there. :)

Thanks
