Disable TPM encryption (without loosing data)

[skrajnik]

Hello,

I have a problem with my probook 450 G5.
System has two drives, one ssd and one hard drive.

All started with system m.2 drive faliure.

After trying to get my work data back, I discovered that the drive is encrypted and cannot be read at other computers.

This is done automaticly on all modern laptops!!!?? (without any warnings about this)

So after many tries, services, data recovery specialists, we descovered that data is lost.

I replaced the ssd drive, installed win 10, to see if the other hard drive could be accessed. And it was possible to access data.

Now - I want to disable encryption on the laptop completely.

1. How can I do that, for both drives, without loosing data?

2. If I disable TPM module in win 10 - will this decrypt the drives?

3. At the end, I want to disable TPM chip in BIOS - when do I do it?

Thank you and have a nice day!

Hi,

1. yes, you can do that.

1. Firstly, check, encrypted drives or not. Open Command Prompt or Windows PowerShell as administrator. To do that quickly press Windows Key + X to open [edit]and choose Command Prompt (Admin) or Windows PowerShell (Administrator) from the menu.
2. When Command Prompt opens, enter manage-bde -status
3. See drives that encrypted and remember drive letters.
4. Now enter manage-bde -off X: command and run it. Be sure to replace X with the actual hard drive letter.
5. Decryption process will now start. Keep in mind that this process can take a while, so don’t interrupt it. To check status of decryption, you can enter manage-bde -status again and again to see the process.

2. No, it don't decrypt your drives.

3. When decryption will finished, you can do what you wish.
