How to Fix: Which drive is the "data drive" referred to in the Bitlocker error "The data drive specified" where would it be set to "automatically unlock"?

BitLocker error on Windows 10 Pro with Bootcamp on MacBook Pro

Quick Answer: Check the BitLocker settings for the data drive and ensure it is set to automatically unlock.

The error 'The data drive specified' in BitLocker on Windows 10 Pro using Bootcamp on an Apple MacBook Pro [2016] is frustrating and can be challenging to resolve. This issue typically occurs when the user attempts to enable BitLocker on a non-operating system drive, such as a data or secondary partition.

In this guide, we will walk through the steps to identify the correct 'data drive' and configure it for automatic unlocking in BitLocker.

🔍 Why This Happens

  • The primary reason for this error is that BitLocker requires a specific drive to be designated as the data drive. This drive should not be the operating system drive (usually the C: or D: drive). Instead, it's typically one of the available secondary partitions. The user may have mistakenly selected the wrong drive during the setup process.
  • Alternatively, the issue could be due to incorrect configuration or missing settings in the BitLocker setup process. In this case, we will need to review and adjust the settings accordingly.
