Usb broke off on the inside of my new 3tb hard drive

does anyone in New Zealand Know if i can fix My WD Extenal 3tb or get my files back 

If you open the case you void the warranty. If the drive came with Smartware the data is hardware encrypted  so hooking it up without the circuit board is useless. You might be able to get a new USB port soldered back on. Other than that look for a replacement board on Ebay. Look at posts or PM fzabkar he knows the most about this.
