VDS_E_INVALID_SPACE

VDS_E_INVALID_SPACE means that the extent or range supplied to VDS is not valid free space for the operation. This can mean the selected bytes are already allocated, outside the disk layout, misaligned for the request, or otherwise incompatible with the requested object.

What to check

Refresh the disk layout and confirm the start offset and length against the current unallocated extents, not an earlier display.
Validate units, offsets, alignment, and sector-size assumptions in automation before sending the request.
Avoid treating this as permission failure: first verify that the requested range is genuinely free and belongs to the intended disk.
