Well, I bought a hard disk last week, it was broken, so I brought it back and got a new one, a few posts later, here I am again. I did a clean install of XP on the new hd and made it the first hd in my bios. After I was done installing all my software and stuff I noticed a few weird folders on my old hd, which was now the passive, second hd. These files looked like: MSI*****.tmp (*=random looking numbers and letters) When I wanted to put off my pc last night, I had a warning that a portion of that hd was faulty or corrupt or something and when I put on my pc this morning it automatically went into chkdsk and started to rewrite the disk on several places. Now I have lost many of my data and also a part of the old hd. It still sez there is 85 gb free space left on p, this is the exact amount as before, but the folder that's gone was about 60gb, so where did that 60 gb go to? Is this a hd crash or something? I am having suspicions about windows restore having something to do with it. Like that the old windows is also trying to make restore points or something. Anyway, should I format this disk or what? I stopped the chkdsk utility because for about 10 minutes it repeated: writing 0 at 12999 or something like that. What the heck is going on?
