It's really 31.5KB (63 sectors x 512b per sector). It's important to note that AF drives don't require alignment to a 4k boundary to WORK, they require one to not have sh*t performance. Your clone is aligned using the ancient, outdated 63 sector offset, and therefore would suffer performance degradation on an AF drive, SSD, or a striped RAID volume.
