[SOLVED] can't see dvd drive

[uniquegeek]

hi folks... i installed recent version of kubuntu with a cdrom drive, installed the ubuntu desktop (and am now using that). Then I switched out the cdrom drive for a dvd-rw.

Menu: Places -> computer only gives filesystem (my hard drive) and LaCie (USB hard drive.) /mnt is empty. I can press the button on the drive, and it opens and blinks... I can insert a disc. Just can't access it anywhere. Dvd is only device connected with PATA, my hard drive is SATA. Can someone please push me in the right direction to fix this?

Have you checked /media/cdrom0 folder?

[uniquegeek]

Thank for a quick reply. There is a /media/cdrom0 folder, and it's empty.

Been doing some more research: if I do

sudo lshw -C disk

I only get:

  *-disk

mtab, if you need it:

Deciphering an answer off of other forums is proving difficult... problems aren't quite like mine either, that I've found....

Does these commands list correct info of your drive?

sudo hdparm -I /dev/dvd
sudo hdparm -I /dev/cdrom

Have you tried any other DVD/CD/Audio CD?

[uniquegeek]

Out of both of those is
"No such file or directory"

When I open Kaffeine and "Play Audio CD" it gives me
No Audio CD found

I can press the button on the drive, and it opens and blinks... I can insert a disc.

That means it has power - nothing else.

Are you sure the jumper on the DVD is set correctly and that the BIOS is set to recognize it?

Does it show up during Linux boot?

dmesg | grep -i dvd

What do these show?

ls -al /dev/hd*

ls -al /dev/sr*

[uniquegeek]

Tried the commands:
1) nothing
2) nothing
3) nothing that looks like a cdrom

That means it has power - nothing else.

Ah. Ah....? I did not know it was possible for the drive to open with out a data connection.

I did check both ends of PATA connector at one point, but I went back and re-plugged them again.

I checked the BIOS, it was not auto-detecting. I then even switched things around (CD/DVD) between my old and new computer again. I actually had to flip the new machine on its side so I could get a good grip and connect the ATA connector into the drive again... this time it was more than looking "well-connected", it actually made a bit of an audible click. Lo and behold, auto-detect in BIOS now sees it.

The OS now sees it too. Thanks folks.

(Learned a couple new commands in the meantime, at least.)
