External DVD writer in Compaq V3424TU notebook

Now you have to deside weather you want to buy a U.S.B. floppy Drive or U.S.B. optical drive.
Both has to work ,but for a try if you have any existing drive ,just buy a external U.S.B. casing and fit your or any existing drive in it.Just try with it.This is more costeffective solution

It is very simple to install a new internal DVD/RW. There is only one screw on the bottom of the laptop that holds the module in. Remove that screw, slide the old unit out, and insert a new rom. Don't forget to replace the retaining screw.

Hope this will solve your problem, and please feel free to rate this advice.

Good luck
