VDS_E_LBN_REMAP_ENABLED_FLAG

VDS_VF_LBN_REMAP_ENABLED is a provider capability flag for allowing dynamic relocation of a volume on disk. Microsoft documents it as unsupported for basic or Microsoft dynamic volumes and supported only by some third-party volume managers. This HRESULT therefore identifies a provider capability mismatch, not an invalid Boolean value or a damaged volume.

Why this state matters

Before setting volume flags, determine which VDS provider owns the volume and which storage model is in use. Copying a flag mask from a different provider or product can cause this error even when the volume itself is healthy. Do not replace the flag with HIDDEN, READONLY, or another attribute: those flags have different semantics and different scope rules.

Diagnostic focus

Capture the provider identity and the exact ulFlags mask supplied to SetFlags.
Confirm that the provider explicitly supports LBN remapping before requesting the flag.
Do not treat ordinary Microsoft basic/dynamic volume support as evidence that this third-party volume-manager feature exists.
Remove only the unsupported flag after verifying that the caller does not depend on relocation semantics.
