STATUS_VOLMGR_DISK_SECTOR_SIZE_INVALID
STATUS_VOLMGR_DISK_SECTOR_SIZE_INVALID means that the target disk's reported sector geometry is incompatible with the requested Volume Manager operation. It does not say that a filesystem allocation unit is wrong, and it should not be "fixed" by choosing a different cluster size.
The geometry seen by Windows may be exposed through a virtual disk, RAID controller, USB bridge, or storage array rather than directly by the physical media. A copied layout can fail when its offsets and lengths were prepared for a different logical-sector model.
What to check
- Query the target physical device rather than assuming the sector size of the source disk or a mounted volume.
- Inspect the exact offsets and lengths passed to the layout operation for sector multiples.
- For virtual or layered storage, verify the presentation from the controller and the guest OS before changing any layout metadata.
