2TB limit for hard drives in Windows 7

Have a 3 Terabyte harddrive, Win 7 only recognized it as 2.2 TB partition and 800 GB partition, could not get one 3 TB partition.

Jeff Hughes has all the details on the 2 TB limit.

Have  to create a GPT (Guid Partition Table) disk.

Open Administrative Tools, then Computer Management, then right click on disk name, far left side, you should see "Convert to GPT disk"on the menu drop down.




A disk configured to be GPT rather than the MBR style would have a 32 sector partition array instead of a tiny 64 byte partition table.

The partitions that can be defined on a GPT disk can be up to 16EB in size.
