What does Windows 11 exclamation mark on drive mean? This post will explain it for you and guide you to remove the yellow exclamation mark on your Windows 11 hard drives.
If you've installed or updated Windows 11 and notice a yellow triangle warning on your hard drive without any action on your part, don't worry – it's an easy case! Typically, after the out-of-box experience (OOBE), if your device enters Sleep or Hibernate before BitLocker Device Encryption completes, a yellow exclamation symbol might appear on the drive icon (usually the C drive).
In simple terms, the yellow triangle warning on your hard drive means that automatic device encryption isn't activated, and your data isn't protected by BitLocker. The solution is straightforward: just enable this function.
No need to worry if you see the yellow triangle warning on the C or other drives. Just follow the solutions below to resolve Windows 11 exclamation mark on drive.
Now that you know the yellow exclamation mark is not a complex problem, and you can follow these 3 fixes to remove the Windows 11 exclamation mark on the drive.
As mentioned earlier, the exclamation mark on the hard drive in Windows 11 typically indicates that BitLocker is not enabled. Therefore, enabling this function is a common solution. However, not all editions of Windows support BitLocker. According to Microsoft's official information, users of Windows 11/10 Home do not have access to this function. They must pay at least $99 for upgrading to Pro or higher versions.
Luckily, AOMEI Partition Assistant Professional has a solution. Its BitLocker feature lets Home users use this encryption thing, and it helps you back up the recovery key, change the password, lock the drive, and turn off BitLocker.
Step 1. Install and open AOMEI Partition Assistant Professional. Go to the "Tools" section and choose "BitLocker".
Step 2. Pick the drive partition you wish to encrypt and tap on "Turn on BitLocker".
Step 3. Create a password, verify it, and press "Next" to proceed.
Step 4. Decide how to back up your recovery key: either "Save to a file" or "Print the recovery key". Then, click Next to start the encryption process.
The exclamation mark on the hard drive in Windows 11 sometimes also means there are hard drive problems. You can use either CMD or the installed AOMEI Partition Assistant to check and repair them.
First, open the Command Prompt by pressing the Windows key + R, typing "cmd," and pressing Enter. Make sure to run it as an administrator. Here are a couple of commands you might need:
chkdsk: Shows the status of the volume but doesn't fix errors.
chkdsk [drive letter]: /f: Checks and fixes errors on the specified volume. For example, if you want to check an external hard drive for errors in Windows 11, replace [drive letter] with the correct letter for that drive.
If you use chkdsk without the /f parameter on a partition that's currently in use, it might show false errors because it can't lock the drive.
For a comprehensive check and repair, run chkdsk f: /f /r /x. The /r option fixes bad sectors, recovering readable data, and /x ensures the drive is dismounted before the process. The /r may not recover all data, so please schedule regular backups as a precaution.
If it seems complicated, you can use AOMEI Partition Assistant, which provides a straightforward Check Partition function.
Then, you can choose what you need to check the problematic partition.
Generally, the yellow exclamation mark on the C drive or other drives can be fixed using the methods mentioned above. If the issue persists, it may be time to reset the Windows device. Resetting your PC means bringing it back to the way it was when you first got it, similar to factory reset, but your data stays safe. Still, it's a good idea to back up your Windows 11 just in case something goes wrong.
Click on the Start Menu icon and choose PC Settings. Inside, pick Update & Security, then select Recovery on the left side. Click the Get started button on the right side. Lastly, follow the on-screen instructions to complete the process.
Usually, after completing BitLocker Device Encryption, restart your PC. The Windows 11 exclamation mark on drive will then disappear. If not, check the hard drive and reset the Windows device can be helpful.
As you can see, AOMEI Partition Assistant can offer you various solution when solving problems. If you have downloaded it, it is advisable to run App Mover to move installed programs to another drive for space expansion. Besides, the Rebuild MBR feature makes it easy to fix boot issues at home on your own. For Windows Server users, this software provides the AOMEI Partition Assistant Server edition.
