I have a friend that thought that but they had never seen the new SATA drives and thought the hard drive (not to be confused with the casings) was somehow integrated into the USB case.
the usb port on my wd mypassport 500gb is damaged and no longer works. i disassemble the harddrive thinking i could put the drive in a new case but the drive and the board are all one piece. i did notice another set of pins on the drive. i was wondering if there was another type of cord that could be used to pull my files off of the drive.
