Recover files from redirected My Documents folder from corrupted Windows system

> A user in our company had created/modified some documents while
> offline w/ his laptop. Windows was then corrupted to the point it
> would not boot, so I had to recover his data by hooking the HD up as a
> slave and copying his profile folder under Documents and Settings. I
> was not able to see his C:\documents and settings\<profile name>\My
> Documents folder looking at the C: drive this way.
>
> Is there a way to recover any of the information saved in a redirected
> folder? I'm assuming it might have something to do with the proper
> credentials being used to view the profile's information. If he is
> logged on with a newly rebuilt image, new SID, etc. how can I import
