Is it possible to set up a NAS on a drive in your PC?

I bought a MyBook World Edition about a year ago, and it's always been a pain. It worked fine for awhile, but once I installed Vista, everything went to hell. I could sometimes connect to it, sometimes not. It would work fine for a week, then crap out, etc. I finally got fed up with it and dismantled the whole thing and threw the 1TB drive in my own PC, since I needed the space anyway. As of now, I have an FTP server set up (my whole family uses the drive for movies, games, backup, etc.). It works ok, but you aren't able to watch movies directly from it like you could with the MyBook/Mionet. My question is am I able to have a similar set up like I did before when the MyBook was in one piece? I'd like to keep the drive IN my PC this time, though.

what you need to look up how to do is "map a network drive", that will give access to you on the network and assign it a drive letter on other pcs.

that's because most wifi routers and such don't allow the wireless and wired clients to see each other on the network. My actiontec 701 wg has it built in as a "security" feature...it's pretty stupid I think.

well at least your wifi isn't segregated like mine...cool. I never use the wireless part anyhow, but it's stupid that it does that. probably your file permissions or some kinda permission then gl

Actually, I figured it out, heh. My Laptop and Desktop had the same name on the workgroup, so it was only letting one of them on at a time. I fixed everything and it works great.
