3 TB HDD shows up as 750 GB?

[coocoo bananas]

I cant figure out why my seagate 3 TB HDD shows up as a partition of 750 GB. I have tried reformatting and deleting the partition to no avail. I also tried swapping sata cords with that and another drive. It is formatted as GPT and NTFS. Is that correct? Any help would be really appreciated.

coocoo if you dont have a newer efi motherboard then your bios of the mb is having a hard time seeing the drive as it is. if you do have a newer motherboard make sure the bios is updated and the drive on the intel or amd sata ports. if you do have a older mb and bios some of the newer drive have size limit jumpers to help older mb see the drive as two smaller drives.

Its weird it used to show up as the correct size, but i had to reinstall windows... now it is 750 GB. Motherboard is a z77 and bios is up to date.

when you reinstalled windows did you go into advance mode and remove the old partion first and then rebooted?? if windows set the drive up right there should only be the system partion and windows data one.

try using diskpart tools and windows disk manager make sure that it sees the drive as it full size. if not run hdtune or another disk check program to see if there an issue.
