How to identify 4t hard drive in win7

Win7 cannot recognize 3TB and 4TB hard drives. Reasons:

Due to the limitations of the traditional MBR partition mode: the current mainstream motherboard BIOS For example, for the MBR partition, each sector is defined as 512 bytes, and the disk addressing is a 32-bit address. The maximum disk capacity that can be accessed is 2.19TB (232*512byte). (Recommended learning: PHPSTORM )

Windows starts from MBR, so each MBR is limited to 2.19TB.

This is one of the reasons why 3TB and 4TB hard drives cannot be recognized normally.

The reason why only 2T is recognized is that the hard disk format is MBR and needs to be changed to GPT.

The following is a detailed introduction:

1. Use the [Win] [R] key combination to open [Run], enter [cmd] during run and press Return Press the Enter key to confirm;

2. Enter [diskpart] directly in the window. After completing the input, press the Enter key to confirm, and you will enter the disk management command;

3. Then Continue to enter [list disk] to bring up the list of computer disks; see the disk number we need to modify, here we take 0 as an example;

4. Directly enter [select disk=0], and press Press Enter and you will see a prompt that disk 0 is selected; then enter the [convert gpt] command to convert to GPT.
