Give the lsblk(8) command a try. It should give you a display something like this: [dales@zothique ~]$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 931.5G 0 disk ├─sdb1 8:17 0 512M 0 part /boot . . <snipped for brevity> . sdc 8:32 0 298.1G 0 disk └─sdc1 8:33 0 298.1G 0 part /srv/musicdata sr0 11:0 1 1024M 0 rom sr1 11:1 1 6.1G 0 rom [dales@zothique ~]$ sr0 is my desktop's internal DVD drive. It's empty, but still shows the "1024M" size entry. sr1 is a Sony portable DVD drive that connects via USB; it has a video DVD in it. Since sr0 is always connected, it always has an entry. The USB drive only shows up if it's plugged in. If your internal DVD doesn't show up, my guess would be that your hardware is faulty. Another thing you can try is watch /var/log/messages while you insert a disk in the DVD drive. Use "sudo tail -f /var/log/messages" at the command line. This will show the last few lines of the file, then watch the file and print any new lines that get added. Use <ctrl-c> to exit when you're done. > 2) I looked at the service manual for my T61 and cannot figure out the > drawings.

I don't have a T61, but I did have a T40 and still have a Dell Inspiron. In both of them the DVD drive connector is soldered directly to the motherboard. I imagine that the T61 is no different. If you have a very fine-tip soldering iron, it's possible to solder a new one on. The fun part is taking out the old one. The traces and pads on a laptop's motherboard are _very_ fine and delicate. It's all too easy to tear them up without wanting to. My recommendation would be to buy another used T61 and use this one for parts. Sorry I couldn't be of more help. --Dale -- "Imagine if every Thursday your shoes exploded if you tied them the usual way.
