BitLocker is an inbuilt Windows encryption technology that protects your data from illegitimate access by encrypting the drives. It requires authentication before it is unlocked for regular use as well as unauthorized access by intruders. Generally, many users have not been able to turn on BitLocker for their USB and cannot see the USB in the BitLocker settings. It has been observed that the BitLocker option is not seen when you select the USB drive in the File Explorer.
This issue is encountered when the USB drives file format is not compatible with the BitLocker application or the encryption service of Bitlocker is interrupted. Also, there are chances of wrong system Group Policy settings causing this error. In this article, you will find some fixes to overcome this issue of not being able to turn on BitLocker for USB.
We suggest you make a check of the following points before moving ahead with the fixes.
1. Take a backup of the important files and folders on the USB drive.
2. Make sure you are not using a Remote Desktop Connection to enable the BitLocker encryption on the USB.
3. If the USB drive does not have storage space available, it would raise this issue with BitLocker.
4. Update your Windows and drivers to the latest version.
