BitLocker Encryption Incomplete: External HDD BitLocker Failed (89.2% Progress)
BitLocker is a full disk encryption feature included with Windows Vista and later. It is designed to protect data by providing encryption for entire volumes. However, there are instances when the encryption process fails, leaving the user with an incomplete encryption and an unprotected external HDD.
Background
BitLocker encryption uses a Trusted Platform Module (TPM) to help protect user data and ensure that the computer has not been tampered with while the system was offline. In some cases, the encryption process can be interrupted or fail, leaving the external HDD in a vulnerable state.
Troubleshooting BitLocker Encryption Failure
If you encounter a BitLocker encryption failure on an external HDD, there are several steps you can take to troubleshoot and resolve the issue. In this particular case, the user was trying to encrypt an external HDD using BitLocker, but the process crashed at 89.2% progress. After rebooting and removing and re-attaching the disk, the encryption process did not continue.
Step 1: Check the System Logs
The first step in troubleshooting a BitLocker encryption failure is to check the system logs for any error messages related to the encryption process. This can be done by opening the Event Viewer and looking for errors in the Application and System logs.
Step 2: Repair the File System
If the system logs do not provide any useful information, the next step is to repair the file system on the external HDD. This can be done using the chkdsk command in the Command Prompt. For example, to repair the file system on drive E:, you would use the following command:
chkdsk E: /fStep 3: Resume BitLocker Encryption
After repairing the file system, you can try to resume the BitLocker encryption process. This can be done by opening the BitLocker Drive Encryption control panel and selecting the Resume Encryption option.
Preventing BitLocker Encryption Failures
To prevent BitLocker encryption failures in the future, it is recommended to ensure that the system meets the minimum requirements for BitLocker and that the latest Windows updates are installed. Additionally, it is important to properly shut down the system and avoid interrupting the encryption process.
