Thank you for the help

I have a few more questions to ask you guys
I have installed Ubuntu quickly with no errors and did a format on my 30GB hard drive before hand. It is up and running smoothly but I have just a few newbie questions for you guys
I have my 30GB hard drive which the OS is installed on showing up fine. However I also have an 80GB hard drive which I use for music and games that isn't showing up anywhere. Is there something I need to do so that my second hard drive will be recognized?
Secondly I'm not sure which audio/video drivers I'll need to install to be able to play music/movies, play games etc. I have a JVC sterio system connected to my computer via USB but cant seem to get audio playing.
Also, I'm unsure of which hardware I have, does Ubuntu have its own version of 'dxdiag' to find this out?
Any help for this linux newb is much appreciated
