I. How to decrypt encrypted hard drive on Windows and Mac?

1. Use file encryption certificate to decrypt (applicable to Windows)

Windows 10 ‘s Encrypting File System (EFS) allows for storing information in an encrypted format on the hard drive and controlling access. A file encryption certificate verifies identity when encrypting and decrypting files.

If you have a file encryption certificate, you can easily decrypt your hard drive and access data on your hard drive normally. The specific operation steps are as follows:

Step 1: Run the Windows computer, press the ( Windows+R ) key at the same time, then type (


       certmgr.msc

) in the search box and press the (

) key to execute the command.

Step 2: Select the (Trusted Publishers) option, then locate the (Action)-(All Tasks)-(Import) option in the top menu bar. Follow the certificate import wizard and upon completion, decrypt the hard disk partition using the certificate. Transfer all data to the new device for browsing and normal use.

If you have not used the certificate function, you can also use the following method to decrypt the hard disk.

2. Use the Diskpart command to decrypt the encrypted hard disk (for Windows)

This method is equivalent to formatting the hard disk , clearing all data , rebuilding partitions , and assigning file systems . It is recommended to proceed with caution . Back up data if there is a password , then use this method to unencrypt the hard disk . Operation steps :
