I'm not sure if this will work or not but if you are desparate enough, no harm trying:
1. Have Ontrack EasyRecovery installed in ANOTHER computer and read up the Help file to learn about how to use it to retrieve lost data
2. Physically install the hard drive that has the document(s) you want in that computer as slave drive (I don't know if it will work if you install that hard drive as an external hard drive, say in an external hard drive enclosure)
3. Launch the EasyRecovery software
4. Pray hard that your wanted documents are still intact!
p.s. You can obtain free trail version of the software here:
