[Solved] DVD drive not detected after fresh install

I installed Arch today on a machine with Windows XP.  I was previously dual booting with Mint Linux.  The dvd drive works with XP and previously with Mint, but I cannot seem to get Arch to recognize it. After lots of google searches it seems I should have a /dev/sr0 entry, but one does not exist.  The output of:

$ dmesg | grep sr
$  

is nothing. The output of:

$ ls /dev/sr*
ls: cannot access /dev/sr*: No such file or directory 

also results in nothing.  Trying to mount the drive, results in this:

$ sudo mount /dev/sr0 /mnt/cdrom
mount: special device /dev/sr0 does not exist

Using wodim also results in nothing:

$ wodim -checkdrive
Device was not specified. Trying to find an appropriate drive...
wodim: No such file or directory. 
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

. Any suggestions?

Hi, and welcome to the forum. Are you in the "optical" group?

Re: [Solved] DVD drive not detected after fresh install

WonderWoofy - it does look similar.  Thanks.  I will be following that thread as well. 

The troubleshooting on that thread seemed to be heading towards a kernel issue, but the kernel hadrons123 installed that fixed the issue for him (3.6.2-1) is the one already installed on mine. 

The other difference is that agkbill's DVD drive has been working and recently stopped, whereas mine has not successfully started working under Arch yet.

I noticed that there were several items that have changed in the install guide since the last time I installed Arch.  To name a few:
systemd is new,
rc.conf, rc.local are gone,
grub uses grub.cfg now instead of menu.lst (took awhile to figure out what I needed in there, but I was able to get grub working after a few false starts)
logs seem to be under journalctl (I have no syslog or boot log that I can find),
the guide no longer has me create symlinks for the optical drive

I installed udisks2 and udevil in my attempts to autoconfigure the DVD drive, but that is not working as I expected it to.

Re: [Solved] DVD drive not detected after fresh install

I finally figured out what was going on.  Bad motherboard.  The non-working DVD drive was the first indication. 

Yesterday the computer died and after swapping out components with a working computer, the only thing not working was the motherboard. I swapped out the motherboard and the DVD drive works fine with Arch.
