Main boot SectorThe main boot sector is located on the entire hard disk 0 cylinder 0 Head 1 Sector {(cylinder, head, Sector) | ( 0,0,1)},bios will jump to the first instruction in the MBR after executing its own inherent program. Take control of the system to the MBR. The main boot sector consists mainly of three parts: the Master boot record MBR (master boot recording or main boot record), the partition table DPT (disk

Main Boot Record), the hard disk partition table DPT (Disk Partition Table), and the ending flag. For a hard disk, the possible number of bytes in a sector is 128 x 2n (n = ). In most cases, take n = 2, that is, the size of a single sector (sector) is 512 bytes. In the master boot records of a total of 446 bytes, the MBR boot program occupies the first bytes (offset 0 h ~ Offset 1bdh), followed by 64 byte

When OS X 10.10 is upgraded, the partition of the hard disk becomes a logical partition (Logical Volume Group). This way you cannot partition the disk using disk tools, including resizing, deleting and adding partitions, and so on. If you need to modify or delete a partition within an OS X 10.10 system, you need to con

With SATA interface (check its order according to Linux kernel sda,sdb ...) As an example,1, the limit of the hard disk, can only set up 4 partitions (primary partition + extended partition), the path is as follows,/dev/sda1/dev/sda2/dev/sda3/dev/sda42, the operating system limits, the extended partition can only have 1, may be 3 (or the following) primary

To do an experiment to illustrate the problem:1.

store the total sector number of partitions, the maximum can represent 2 of 32 of the number of sectors, in 512 bytes per sector, each partition maximum can not exceed 2TB. When the disk capacity exceeds 2TB, the starting position of the partition is not represented. In the hard drive capacity of today, 2TB limit has already been broken. This shows that the MBR partiti
