Editor to share with you how to identify 4t hard drive win7, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Win7 does not recognize the reasons for 3TB and 4TB hard drives:

Due to the limitation of the traditional MBR partition mode: for the current mainstream motherboard BIOS, the MBR partition defines 512 bytes per sector, the disk address is 32 bits, and the maximum disk capacity that can be accessed is 2.19TB (232*512byte).

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

This is one of the reasons why 3TB and 4TB hard drives can not be recognized properly.

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

The following is a detailed description:

1. Use [Win] + [R] to open [run], enter [cmd] during the operation, and then press enter to determine.

2. Enter [diskpart] directly in the window, press enter to confirm after the input is completed, and you will enter the disk management command.

3. Then type [list disk], call up the list of computer disks, and see the disk number we need to modify. Take 0 as an example.

4. Enter [select disk=0] directly, then press enter to prompt that disk 0 is selected, and then enter the [convert gpt] command to convert it to GPT.
