There typically isn't a master/slave setup with SATA. So, did you format both disks? And are they both plugged in? Power cables too? Do they both show up in BIOS or during POST?

Slavery is bad or something.

Does the drive show up in BIOS? If so, you may need to control panel ->administrative tools -> computer management -> disk management and enable it.

It is if you are the slave.

thanks for your time and easy instruction zorg took all of 2 min

Happy to help.
