There is nothing you can do to make sure the drive "is flawless" or "absolutely fine". That's the nature of mass production.

I DO know the answer, it's you that doesn't seem to understand. There is no such thing as a flawless hard drive. They don't exist. You will always find something wrong with one if you look hard enough. You can never avoid bad sectors, either fresh from the factory or developing over time. Like I said, that's the nature of mass production.

Since it is from WD, go to their website and download and install their utility package, Data Lifeguard. Use it to Zero Fill the drive. Be VERY sure you do NOT do this to a drive that contains data!!

This operation will write zeros to EVERY Sector of the HDD. It also triggers a background activity built into the HDD that will test every Sector as it goes and replace any that appear weak with a spare good sector. When it is done, there should be NO "Bad Sectors" for Windows to find, because the HDD itself has made the substitutions and Windows can never find the bad sectors it replaced. The HDD will be totally empty, as any brand new HDD ought to be.

Zooshooter is right - there are always some faulty Sectors on a new HDD. But normally this self-diagnosis and fixing process has been done at the factory and the new owner should not have to do it themselves. Since you have had bad experiences and are "gun-shy", you can force the HDD to re-do the process with a Zero Fill.
