I encrypted a USB drive E: with BitLocker in Windows 10 without any issues. However, when I double click on drive E: in windows explorer I get a popup that says "The BitLocker encryption on this drive isn't compatible with your version of Windows. Try opening the drive using a newer version of Windows.". If I right click on E: drive in BitLocker Anywhere, there is a menu option to 'unlock drive' but when selected, I get the same popup so I can't use the usb drive at all. Please help, thanks.

A: This error occurs when the BitLocker version used to encrypt the drive is incompatible with your current Windows version. Different Windows versions (Windows 7, 8, 10, 11) support different BitLocker encryption modes.
A: Decrypt the drive and re-encrypt it using 'Compatible mode' so the encrypted drive can be accessed across all Windows versions (Windows 7, 8, 10, 11).
A: Compatible mode uses AES-CBC encryption which is compatible with older Windows versions. Windows 10 Version 1511 introduced XTS-AES encryption which is not compatible with older versions.
A: No, if the drive was encrypted with XTS-AES encryption (default in Windows 10 1511+), it cannot be opened on older Windows versions. You need to re-encrypt with compatible mode.
A: If encryption terminated abnormally and the drive is inaccessible, you can use Hasleo BitLocker Data Recovery to recover lost files from the encrypted drive.
A: Generally no, but some users have reported issues after upgrading. If this happens, you may need to decrypt the drive and re-encrypt it after the upgrade.
