In the example below, we have a drive which shows a sector starting at offset x15470000 and another starting at offset x15470200. I’ve also created a file which is less than 512 bytes (actually it is about 317 bytes) which should fit within one sector. However, as can be seen this file actually starts at offset x15470160 and spans two sectors. While the writing did not start at the beginning of any sector it is instead contiguous across the two sectors.
On a computer running Microsoft Windows, one can use either fsutil (technet.microsoft.com, 2012) or chkdsk (microsoft.com, n.d.) to see the sector information.
