Subject: [gentoo-user] the same hard-drives, different number of sectors...

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)...
Jarry
