I can not get access to my files

I had windows corrupt on me and could not get it to work
right so I did a repair install on the disk still did not
work. Went down and got a new disk did a new install
works good. My old disk I took out and put it back in so
I could use it to recover my data. I did not want to
loose any of it.
Now when I try to read things that are stored on that
disk under document and seetings access is denied. I can
onpen other things not in the docs and settings how can I
get around the security. Please help would love
to get to my personal data ? off of my old disk I think
it is windows security that is not letting me see my
file ?
Thank you for your help Aaron
