How to encrypt the hard disk under Windows 2008

Speaking of hard disk encryption, I believe many netizens like to use software encryption, which is simple and fast. But if there is no network or some specific software that can't be used, how can we encrypt the hard disk? It is estimated that few friends know this. Let's introduce this to you. Start - "Run -" cmd enter the command line and enter diskpart, press Enter. Enter list disk, you can see the hard disk number, 0, 1, 2, 3... what. Type select disk x (x is the hard disk number) and select the hard disk you want to partition. Enter clean to clear all partitions on the hard drive (if your hard drive is not unpartitioned).

Enter convert gpt to convert the hard drive to a GPT partition table (basically it can be said to be a permanent conversion, you can't switch back to MBR unless you clean the partition table again with clean). Enter create partition primary size=*** id=yyy to create a data partition that can be used to install the operating system
(id=yyy can be entered without input, it represents the GUID partition type (format, just like the MBR partition table) FAT/NTFS /HFS+ uses a string to represent the partition format, but the GUID is very long and is a globally unique identifier. If you do not enter it, it will be generated automatically when you install the OS
, format the partition. ), a detailed introduction and a list of various partition GUIDs see this).

Then repeat the above sentence to create multiple data partitions. If the entire disk creates a partition, enter create partition primary and enter the list partition to see what the partition number is. Enter select partition x to select the partition. Enter assign letter=D (D represents the drive letter you want to assign to it, just fill in an unoccupied drive letter) Enter exit to exit the diskpart partition tool, and then return to the command line.

When I enter my computer
, I can see that one more disk is out, and formatting can be used. You can also format the input format D by typing the following command at the command line: /fs:ntfs /q /yFormat this EFI partition (D is the drive letter you just set above, ntfs is the file format). Such a new disk will hang up.
