Crappy WinBlows

Figures this **** happens.
So I have a fileserver I had built a while ago, well apparently a bunch of the files are corrupt, Windows doesn't think so, but they don't play in Media Player, file size is there but none of the files play or dispaly images etc. lights are on no one is home.
When I play certain music files they play parts from movies I have saved, WTF @ Winblows. I hate this operating system I am so glad I didn't actually pay for this ****.
Is there any way to get my **** back or do I get to start from scratch all over again?
Oh one more thing **** Western Digital both of these are 250gb drives and every single drive I have ever bought WD brand new has done similar things, I have Maxtors that are older than some of the people on this board and they work fine. WD = Waste dollars
