Instead of throwing the hdd and bought an external hard drive, I told myself as much as it used to 750GB of storage is enough. So the solution of the SATA to USB adapter was the best, then I say take as a case for more aesthetic and less risk of shock.
And the rates are very good in 3.0:
60 mb / s if I did not plug the USB cable and more power.
120 mb / s with this cable.
In short very good product.
