How to completely erase the contents & partitions of an internal WD hard drive


I would like to completely erase or format or do whatever is required to be able to hand over a completely clean hard drive to a third party and feel comfortable that none of my personal information will be compromised because it did not get properly erased.

This internal WD drive is currently located within a Dell Inspiron laptop.

Any help in providing and explaining the necessary steps to do this on the p/n WD7500BPKX would be much appreciated.

Please respond at your earliest convenience.

Best regards :baby:,
