Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit X-Archives-Salt: X-Archives-Hash: 03810ed3c8ea369e5b626da8e853f900 Hi, perhaps someone could explain this to me: I have bouth two the same hard-drives. The same model (Hitachi HUA722050CLA330), the same firmware (JP20A3EA), the same size (500GB). Well, not exactly. Both hdparm and fdisk report different number of sectors (976771055 versus 976773168). Although not a big difference, yet I expected them to be exactly the same (want to use them for raid1). So how is it possible they do not have the same number of sectors? I have bought them from one supplier, even their serial numbers are very close (only the last 2 characters out of 24 are different)...
