Problem with accessing my DVD/RW Drive

[Old and In the Way]

Hoping I can get some expert help from the DUer community here.

I have an HP zd7020 laptop. Recently, the DVD-CD-RW drive has gone dead. I can't get it to access anything on the CDs/DVDs that I put in the tray. Under the properties for the device it reads:

Device Type: DVD/CD-ROM drives
Manufacturer: (Standard CD-ROM drives)
Location: Location 0 (0)

Device Status: This device is working properly.

The drive is an HL-DT-ST DVD+RW GCA-4040N

Any clues? I tried to update the drivers, but it says I have the best driver for the device. In the My Computer window, it shows the device as a DVD/CD-RW drive, but when I click on the properties with a good DVD in the tray, it says
Type: CD Drive
File system: Unknown
0 bytes used/0 bytes free.....

Any help appreciated!

1. Update

Ok, I checked the reader head....well, I blew on the LED and gave the head a little finger nudge....that seemed to do the trick on the DVD drive....was able to get the DVD ROM to work. But I tried to put a musical CD in there....and nada.

2. There is a lot of info on the Microsoft site about that.

There's a lot more than you ever need, but it's a start. :)
