After using a 320GB USB hard drive successfully with Vista, I had to reinstall a clean copy of Vista. After reinstall I used the command line script to take ownership of my hard drive, then attempted to copy + paste the files (286GB worth) onto a new 500GB USB drive. But after a hour or two vista produces an error about "desination permissions" (the drive has been reformatted to NTFS) and only about 110GB is copied over? Whats happening?
