I put my laptop cord in WD book andnow does not work to

Sounds like you fried the circuit in the WD. Hopefully it's not the HDD electronics but only the power-connector electronics.

You could try to disconnect and remove the HDD from the WD book and hook it up to a computer 'internally'. If it's recognized, the HDD itself is probably fine and you should be able to rescue the data.

If not, the HDD electronics are probably fried too, meaning that for data recovery, the electronics on the HDD have to be replaced, which requires a "donor HDD" (of exact the same type). That would be a very expensive data recovery (in both parts and labor).
