We order 9 "Top Grade" 2TB HDD Enterprise Storage from Western Digital and 6 out of 9 have bad sectors. Most of them have 2-6 bad sectors, and a couple had around 50 bad sectors. We used HD Tune to test these HDD over eSATA and also USB
Is it normal to get 2-6 bad secotors?
are there other more effective ways of testing the HDD?
Thank you, and I'll be waiting for your response.
