WebA master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0.. The MBR holds the information on how the disc's … Webthe entire sector. We can work this out as (time for one revolution of disk) / 500 = 6ms / 500 = 0.012ms. So the total time is 8ms + 3ms + 0.012ms ≈ 11ms. We can clearly see that getting to read the first byte of the sector takes a long time, but reading the rest of the bytes in the sector is essentially free. solder paste thickness after reflow
