NET 4000 Chapter Notes - Chapter 7.1.4: Fdisk, Hard Disk Drive
Document Summary
The master boot record (mbr) partition format has been used by many operating systems, including linux, since the 1980s. Because of its age, the mbr partition format has many limitations: The master boot record must be installed in the first 512 bytes of the hard disk. Only four standard partitions can be created on a storage device. The default block size of 512 bytes limits partitions to a maximum size of 2 tb. Many workarounds have been implemented over the years to address these issues: Logical block addressing (lba) allows the use of larger hard disks. Use of 4,096 byte sectors increases the maximum partition size on a disk. A partition is a logical division of a storage device associated with a hard disk drive. A storage device using an mbr can have a single partition or multiple partitions. The most common partitioning scheme divides a disk into two different partition types:
