Best way to test HDD?

I've just bought 3 second hand HDDs. SMART looked good, so set about setting unraid up. I've filled 1/3 of one the discs and it's now reporting an error on the dashboard.

Checking the attributes of that disc I get "197 Current pending sector". From my reading, this is bad.

 

How can I fully test this, and other 2 drives? They are setup in an array, but it doesn't matter that the data is lost and I have to start again. 

 

I've been reading about 'preclear' but confused. That can pre-clear any disc that isn't part of the array. My discs are part of an array.

 

Is preclear the way I need to go with this? If it is, I'll post in it's support thread for help. Otherwise, can anyone suggest another way?

    Run an extended SMART test on each disk.
