Seems the drive is defective. Try another one.
If Mediasmart came with the machine, you should have it. From the description it lets you view movies and photo's (and TV if your hardware supports is) and listen to music. There's other software also that can be used for such function. So I doubt if you can say you "need it". It's rather strange that you don't know how to get it, but somehow found the installer. Since you don't tell why that didn't work, all I can say is: contact the maker.
