Compaq DVD drive issue

[Travis30384]

I have a compaq v6210us laptop. Whenever I use it for a couple hours, the E: disappears. When I start my computer, I can use the e: (DVD RW), but after a while, when I try to use it, it says the e: refers to a location that may be unavailable. This has been happening for about three months.
