Somthing won't let me into my hard drive

Hello,
My computer runs Windows XP Media Center Edition
OK so here is my problem, one day I took some pictures off of a camera.
then my computer starts acting slow and choppy, so realizing that I haven't de-fraged my computer in awhile I run de-frag. Unlike what normally happens it took give or take 3 hours to get to 55%, then in the next 2 hours it does nothing, so I shut the computer off.

When I turn it back on I get the didn't shut down right page, so i go through the safe modes and all that good stuff and none of it works.

So I pop in the restore disk (this has happened before) and it didn't give me the option of restoring my system without deleting all of my files (so I didn't do that).

So like anybody else I try ubuntu (didn't get in my hard drive), kubuntu (also didn't get in my hard drive), then knoppix ( which got into my hard drive but didn't see my files (mabye because the knoppix was in german).

So I took an old slave drive, put my os on it and hooked it up. At first the computer only recignized the drive before windows was completely booted (because it wanted to run scandisk). so i let scandisk run and it got over half dont in some six odd hours and for 12 more didn't do anything, so I shut it off figuring that it would keep doing nothing.
When I turn it back on and go to "my computer" the drive is there (happy day right), I double clik and after a minute I get "inpage error. Please help me!
