The best thing i can tell you is disconnect that drive then connect it to other pc then format it and then connect it back to the same pc and reinstall the os,,hope this can solve your problem

I think some startup script is running on your pc which delete all the file on the particular drive..

Check if the hdd has read-write permission. Check the jumper settings.
