How To Fix 3 TB Hard Disk Drive that Shows 746 GB Unallocated

To use all the space of your 3TB HDD you will need a disk of 64 bit Windows 7 or up. The 32 bit version of operating system uses - MBR (Master Boot Record) type partition system which can partition up to 2TB. That is why the remaining 746GB stays unallocated. The 64 bit Windows uses GPT (GUID Partition Table) type partition system which can handle upto 9.4ZB space.

(Don't forget to Backup your important data first).

For GPT type partitioning:-

1. You'll need a Motherboard that supports UEFI (Unified Extensible Firmware Interface).

2. Enter Motherboard's settings (BIOS) by pressing F2/Delete key.

3. Enable UEFI Mode instead of Legacy.

4. Save and Exit Motherboard's settings (BIOS).

5. Boot 64 Bit Windows disk in UEFI Mode.

6. In the partitioning window if you have any MBR type partition delete them.

7. After deletion create new partitions and install Windows.
