The hard disk installed with the system, Windows cannot read and use the solution

   Clear the EFI system partition and restore the normal use of the disk

   I haven't had anything to do recently, and a Kali Linux has been integrated in the mobile hard disk. Because the Vmware virtual machine is tired and crooked, I am thinking about dual systems. One of the biggest advantages of the mobile hard disk production system is its strong portability, which is why I prefer to choose a mobile hard disk. At the same time, I found a problem. The disk that has been created by the system cannot be read and written normally in Windows. What if we want to reuse the disk someday? Next, I will answer for you:

  Open my computer, we will find that the drive letter of the mobile hard disk cannot be found, don’t panic, right click "My Computer" -> select "Manage" -> select "Disk Management" , here we can see , Our mobile hard disk is similar to the following picture:

  Presumably, everyone has seen that there is an EFI system partition in the disk. If you want to learn more about the EFI system partition, the blogger will also pass you the portal:
   1. Know: What is the EFI system partition?
   2. EFI system partition-Baidu Baike
   steps to delete useless EFI partition. Special reminder, this action will clean up all the data on the disk, so you also need to back up the original disk data in advance to prevent data loss.
  And our task is to use the partition management tool in Windows to clear the EFI system from the hard disk, and then initialize and format the hard disk, you can see the long-lost mobile hard disk drive letter in Windows Explorer .

  1. Open the diskpart partition manager in cmd or PS (poweshell):

	diskpart

  2. In Diskpart partition manager, first check the disk situation:

	list disk

  3. Select the disk you want to clean up, for example, the EFI partition in Disk 2 to be cleaned up here:

	select disk 2

  3. Clear all messages in the disk!

	clean

  Then open the Disk Manager again and complete the initialization of the disk:

  Bloggers recommend choosing GPT (GUID Partition Table). I believe that few people will use xp or win95 now, so MBR is not suitable anymore and choose the newer GPT.

  Format the disk, don't ask, just choose ntfs format!

  Congratulations! The removable disk can be read and written normally in the resource manager again!

  I believe that students who have played Linux will feel familiar with this tool. Yes, it is similar to the Linux fdisk program.
