I used HD Tune Pro to test the speed of my WD10EARS and the average reach max only 70mb/s.
And i found out that my WD10EARS sector size is 512 bytes only.
I’ve use WD Align System Utility and it showed all partition are properly aligned.
I even used Data Lifeguard Diagnostics to check,but physical drive there showed none.
I suspect my WD10EARS is faulty with the sector size.
Is there any other solution or i should send for RMA?
