How to Fix If BitLocker Fails to Encrypt Drive

BitLocker is a security feature that encrypts your hard drive on your computer for security purposes. It’s a Microsoft product that is available on the latest Windows versions by default, from Windows Vista to Windows 10 pro. But it’s not foolproof and sometimes fails to encrypt the drive from time to time. When Bitlocker fails to encrypt the drive, then here are some troubleshooting steps to fix the problem. 

BitLocker runs on Windows OS, but you need a storage utility with at least two partitions and a Trusted Platform Module(TPM) if you really want to use this feature on your PC. Now, what is TPM? Then it is a chip that checks the authentication of your Firmware, Software, and Hardware. However, if TPM notices any change among these, it would automatically enable the restricted mode to protect your system data from attackers or intruders.

Meanwhile, BitLocker is an inbuilt tool in Windows 10 that can be used to protect the data of your hard drive from offline attackers. Unfortunately, as with any other software BitLocker also has some flaws in it. Many users recently complained that the hard drive is unusable when they migrate from older OS to new and guess what?
