Missing disk space after reinstall Windows XP

June 9, 2009 at 15:48:45
Specs: Windows XP
I have a desktop with 150 Gig hard drive. I had to reinstall Windows XP b/c I had a virus that I couldn't get rid of.

Before reinstalling I only had 1 or 2 free gigs (148 or 149 were used). Now after reinstalling, obviously all of my data is gone, but it is still showing that I only have 1 or 2 free gigs. What is going on?

If I go into my C drive there is no trace of any of my old documents or any of this mystery space that is being taken up.

But what is weird is that if I go into my program files folder, all of the software that I had installed before reinstalling windows is still there (and I can still start up that software). But none of it shows up in my start menu. And when I log into windows, no other users are available... What's going on???

You probably didn't reinstall. When you put the cd in, you probably chose to repair instead. Put the windows cd in, erase the formatted partition, reformat the whole thing into a partition using either fat or ntfs, then reinstall windows on that. All of your information will be gone, it will be as if you just got a new computer.

Aha solved!

I went to 'Documents and Settings/user'. My 'My Documents' folder was still there (where my 149 gigs of data was). It was saying the folder was empty, but I could not access it. So I took ownership of it. See link for taking ownership:


That enabled me to get at all of my old data that I thought I had lost! YAY! And that's where the missing 149 gigs were obviously. Perhaps someone else will be able to learn from this =)

ldzppln0, I thought I did reinstall. When I tried to repair it did not work, so I had to go forward with the full install. And it kept warning me that I would lose all of my data, etc. Eh, but I have no idea what I did.

I read somewhere that I was supposed to reformat. Otherwise, I would just make another partition. I don't think I reformatted. Eh, I have no idea.
