STATUS_FVE_FAILED_WRONG_FS
Meaning and context of STATUS_FVE_FAILED_WRONG_FS
This is a file-system compatibility decision made before encryption can continue. It differs from an I/O error: BitLocker has rejected the target configuration rather than reporting a failed sector read or write.
Verify the actual file system, the volume type, and whether the requested operation is intended for an operating-system drive, fixed data drive, or removable data drive. The supported configuration can depend on the Windows version, volume role, and policy, so copying a workflow from a different drive class can be misleading.
Do not convert or reformat a volume merely to suppress the status without confirming its role and backup state. If the target has a supported file system but does not reach the end of the volume, that is instead represented by STATUS_FVE_FS_NOT_EXTENDED.
