So, you tried using a different SATA data cable, on the same SATA motherboard header, and it Partition master showed the drive bad still?
You tried a different SATA data cable on a DIFFERENT SATA motherboard header, and Partition master still showed the drive bad?
You tried a different or same SATA cable with an entirely different SATA power cable, not just a different connector on the same power cable and a not a cable plugged into the same SATA power cable socket on the PSU (If a modular PSU) and Partition master still showed the drive as bad?
But when you run WD lifeguard tools extended test, it shows ok?
Makes no sense.
You might also try downloading the free version of Hard disk sentinel and checking drive health there plus running whatever tests it will allow. I'm not sure which tests are free or not anymore since I use the paid version and have access to all the tests, but in the end like I said earlier it's likely that it's just done for whatever reason and like fzabar said, if it's identifying itself by it's controller, then there's clearly something wrong at the hardware level.
Regardless, I would never again trust this drive for anything important so it might be best to simply round file it.
