Exclamation Mark on Disks

You may be worried if you see a Yellow Exclamation warning on Disks such as Local Disk C to your computer. However, there is nothing to worry about. This exclamation point is related to the BitLocker drive encryption implementation. What this means is: This warning occurs because BitLocker protection is suspended. If you ask why this situation occurred, I didn’t do anything; This can happen when you turn off the “Secure Boot” or “TPM” setting in your bios. So what is this BitLocker let’s explain a bit:

What is BitLocker?

BitLcoker is a strong encryption security that prevents external access to your files by encrypting your Disks. However, BitLocker is not a protection that asks you for a password when you open the Disk. BitLocker encrypts all your files, you can access your files normally while your account is open, however, your disk will not be accessible and your files cannot be viewed by outside intervention without logging in to your Account. If you turn on BitLocker it will give you a recovery key. this recovery key is important for you to regain access to the data in case of any possible situation. If you lose this key or format without turning off bitlocker, you will not be able to access your information again.

“C:” in the codes represents the letter of the corresponding disk. For different disks, you should use the letter of that disk. For example: If you want to turn off BitLocker on Local Disk (D), you use the code “manage-bde D: -off”.
