[Host planning and disk partitioning] disk partitioning MBR and disk partitioning mbrRelationship between the disk connection method and the device file name The mainstream disk interfaces areSATA interface. SATA, USB, SCSI, and other disk interfaces are all driven by the SCSI module.Therefore, the disk device file names of these interfaces are/Dev/sd [a-p]Format. The order depends on the order in which the Linux kernel detects the disk. For example,

MBR primary Boot Sector resolution and mbr Boot Sector resolution Recently, the structure of the MBR main guide sector needs to be studied in a simple way during image production. Here we record the structure to facilitate later review. Next we will go directly to the question: The MBR primary Boot Sector is located

How is the hard disk MBR format converted to GPT format? This is a lot of small white computer users do not understand. First, on the hard drive GPT format, GPT is a globally unique identity partition table (GUID Partition table, abbreviation: GPT), which refers to a globally uniquely labeled Disk partition table type. It is part of the Extensible Firmware Interface (EFI) standard, which is used by Intel to replace the PC's BIOS, and is used to overri

It is the most important data structure on the hard disk. Generally, our computer hard disks use mbr hard disk partition tables. If the purchas

Therefore, we want to convert it into a Windows 7 system, generally, the computer disk preinstalled with win8 is in the gpt format. to replace it with an earlier version suc

special boot sector that exists in the start part of the drive. This sector contains logical partition information for the boot loader and drive of the installed operating system. The so-called bootloader is a small piece of code that is used to load larger loaders on other partitions on the drive. If you have installed the initial information for the Windows,windows boot loader in this area-if the MBR information is overwritten causing Windows to no

partition table in EBR describes the first logical partition, and the second item points to the EBR of the next logical partition. If the next logical partition does not exist, the second partition is not required. The structure of the MBR partition is roughly described here. If the MBR of the hard disk is damaged, you can copy the MBR of another hard disk to t
