What is sector in Linux partition?
The information about how a hard disk has been partitioned is stored in its first sector (that is, the first sector of the first track on the first disk surface). The first sector is the master boot record (MBR) of the disk; this is the sector that the BIOS reads in and starts when the machine is first booted.
Can you change bytes per sector?
You can’t change the sector size of a hard drive – the sectors are created when the hard drive is manufactured and can’t be changed. You can change the NTFS cluster size (also called the “allocation unit size”) of the file system using Disk Manager as shown by nikorr, but you have to reformat to do it.
