 ## Check sector size
 
 Snapshots with a 4096 logical sector size can only be used to create Ultra Disks. They can't be used to create other disk types. Snapshots of disks with 4096 logical sector size are stored as VHDX, whereas snapshots of disks with 512 logical sector size are stored as VHD. Snapshots inherit the logical sector size from the parent disk.
