with new Hard Drives do i extended test then format or the other way round or neither

Hi

with new Hard Drives do i

• extended test then format
• or the other way round
• or neither

I have had hard drives before that when i have been using the a few days then start erroring so i thought to do a couple of test this time before i start!

i have 6 x 1TB drives WD caviar Green

extended test took 2.20 hours
format about the same so 4.40 each drive

Am i doing this the right way round?

Is it necessary (i would like to do a test)

Before i had 3 returns with hard drive failing to backup then failing the extended test. then backing up , then failing again, then returning

it was a pain

i thought i'd start with the test first this time

any advice welcome

 

I don't think there's anything wrong with doing both tests, however they're doing basically the same thing.

In my experience, drives fail when they fail. Some don't make it out of the box, some last several hours or days, some last many years. Even if you test it for an entire day it could still fail the next time you use it.
