我正在将外部驱动器移动到新计算机上。

该驱动器受 Bitlocker 保护，但我可以解锁它并查看内容。

但是，当我尝试配置自动解锁时，我看到：

C:\>manage-bde -autounlock -enable d:
BitLocker Drive Encryption: Configuration Tool version 10.0.17763
Copyright (C) 2013 Microsoft Corporation. All rights reserved.

ERROR: An error occurred (code 0x80310010):
The BitLocker metadata for the encrypted drive is not valid. You can attempt to repair the drive to restore access.

有没有办法重建元数据？

显然元数据足够有效以解锁卷，所以我想知道错误消息是否正确。

进一步调查显示错误消息不正确。

问题的原因是磁盘被标记为只读。

使用diskpart清除只读标志，然后锁定和解锁卷后，manage-bde -autounlock -enable d:工作正常。
