IIRC, sector size is controlled at the hardware level(used to be set with jumpers and/or low-level format programs?). I seem to recall that new drives don't really have "sectors" anymore, but have supporting circuits/(EE)proms that emulate that?
no, sectors are still 512 bytes (plus ECC and header info) on the physical disk. its the 'heads' and 'cylinders' that are abstracted. there's still heads and cylinders, its just that different zones of the disk have differing sector/track counts.
I got a Gparted live CD and tried to create a partition for 3tb but still the maximum size of partition I could create is 0.75gb. it shows 2.0tb space as unused but If I add another partition it doesn't take(it says no empty cylinders). The version I am tiring to install is centos5.
