1. fire up multiman, blackb0x, whatever ftp & transfer your backup
2. run your lv2 pkg of choice
3. run the fix permissions app that is installed from running the package located here http://www.mediafire.com/?cyi363utdttieux
The app will go through the HD and correct the file permission errors that come with using PL3. I have been using this method after each game backup I install,
however if you install (ftp/copy) 5 at a time the app only needs to be run once and it will fix all 5 games as it does its magic to the entire drive.
Now as far as USB, hampster driven HDs etc I can not say as I do not have any of the above so I have not tested it myself.
