I slaved my boot drive and now I can’t see my documents?

One morning my pc woulnd’t boot and had this error(s):
missing or corrupt
system32\hal.dll
windows\system32\config\system

I tried every trick and no luck, so I have slaved the drive to another drive with Windows XP Pro installed. I can now access the files, except I can’t find the My Documents or the Documents and Settings folder on the slave drive.

Is there a way to find these files without using data recovery software?

If not what data recovery program is recommended?

Thanks
