some files disappeared after move

[Guest]

I've recently added a new faster system drive and am trying to migrate and
reinstall as I go. At first, I found part of the problem with the way I did
this was with the built-in Windows security (I had to take Ownership of the
everything on my old drive before I could access some things). I've done
this, but I've come across a new problem. When I tried to move (this may
have been my first mistake - moving instead of copying) all the contents of
my old My Document folder to my new one - some of the documents appear to
have never made it but have still disappeared from the old drive. Any idea
how this could have happened or how to recover these missing files? I should
note here that during the process, I received a message denying me access to
4 files I know I can never open again (this is due to another completely
unrelated, but sadly similar issue that I don't think anyone/anything but a
heavily experienced hex-editor can solve).

Adding a few more comments.

I've already done a local drive search and found nothing. I've also checked
the recycle bin.

Which leads to one more question that might be relavent. Will restoring to
prior save point restore anything (specifically .doc and .xls files) to the
recycle bin? I know it doesn't affect those types of files in normal folders
(esp the My Doc's folder) but I thought I'd ask about the Trash...
