Advanced Format, a generic term, involves those sector formats employed for data storage on hard drives with more than 512-520 bytes per sector. Many consider Advanced Format a milestone technology in the evolutionary course of hard drive storage.
4K Advanced Format
With the desperate need for delivering higher capacity points and improving Error Correction Capability, innovative and sensitive hard drive manufacturers recognized it had become urgent for them to survive competition by developing large sector sizes. During 2000 to 2009, storage media capacities increased lukewarmly by 44% every year on average. This situation, however, fell far behind what is really needed by users and drastic innovation is required in magnetic recording system technology. Hard drive manufactures, instead, lift the data surface area efficiency by 5% to 13% and increase the Error Correction Capability by altering the length of data field and using 4096-byte sectors (4K) Advanced Format.
What is hard disk?
The hard disk drive in your system is the “data center” of the PC. It is here that all of your programs and data are stored for future retrieval. Your hard disk (or disks) is the most important category of permanent storage used in PCs (the others being floppy disks and other storage media such as CD-ROMs, tapes, removable drives, etc.) The hard disk differs from the other types primarily in three ways: size (usually larger), speed (usually faster) and portability (usually fixed in the PC and not removable).
Magic Partition supports all hard disks recognized by Windows such as IDE, SATA, SCSI, USB external disk, Fire wire disk and so on.
What is disk formatting?
Disk formatting is the process of preparing a hard disk or other storage medium for use, including setting up an empty file system. A variety of utilities and programs exist for this task.
Large disks can be partitioned, that is, divided into distinct sections that are each formatted with their own file systems. This is normally only done on hard disks because of the small sizes of other disk types, as well as compatibility issues.
What is disk partitioning?
Disk partitioning is process of dividing the storage space of a hard disk drive into separate data areas. These separate data areas are known as partitions. A partition editor program can be used to create, delete or modify these partitions. Once a disk is divided into several partitions, directories and files of different categories may be stored in different partitions. More partitions provide more control but having too many partitions may become cumbersome. The way space management, access permissions and directory searching are implemented depends upon the type of file system associated with the partition. Careful consideration of the size of the partition is necessary as the ability to change the size depends on the file system installed on the partition.
What is file system?
The file system is the general name given to the logical structures and software routines used to control access to the storage on a hard disk system. Operating systems use different ways of organizing and controlling access to data on the hard disk, and this choice is generally independent of the specific hardware being used–the same hard disk can be arranged in many different ways, and even multiple ways in different areas of the same disk.
What is computer booting?
In computing, booting (booting up) is a bootstrapping process that starts operating systems when the user turns on a computer system. A boot sequence is the initial set of operations that the computer performs when power is switched on. The boot loader typically loads the main operating system for the computer.
What is LBA?
Logical block addressing (LBA) is a common scheme used for specifying the location of blocks of data stored on computer storage devices, generally secondary storage systems such as hard disks. The term LBA can mean either the address or the block to which it refers. Logical blocks in modern computer systems are typically 512 or 1024 bytes each. ISO 9660 CDs (and images of them) use 2048-byte blocks. The capacity for the sector on the hard disk is usually 512 bytes.
What is CHS?
Cylinder-head-sector, also known as CHS, was an early method for giving addresses to each physical block of data on a hard disk drive. In the case of floppy drives, for which the same diskette medium can be low-level formatted to different capacities, this is still true. Although CHS values no longer have a direct physical relationship to the data stored on disks, pseudo CHS values (which can be translated by disk electronics or software) are still being used by many utility programs.
What are basic and dynamic disks?
Basic disks and dynamic disks are two types of hard disk configurations in Windows. Most personal computers are configured as basic disks, which are the simplest to manage. Dynamic disks can make use of multiple hard disks within a computer to duplicate data for increased performance and reliability.
A basic disk uses primary partitions, extended partitions, and logical drives to organize data. A formatted partition is also called a volume (the terms volume and partition are often used interchangeably). In this version of Windows, basic disks can have either four primary partitions or three primary and one extended partition. The extended partition can contain an unlimited number of logical drives. The partitions on a basic disk cannot share or split data with other partitions. Each partition on a basic disk is a separate entity on the disk.
Dynamic disks can contain an unlimited number of dynamic volumes that function like the primary partitions used on basic disks. The main difference between basic disks and dynamic disks is that dynamic disks are able to split or share data among two or more dynamic hard disks on a computer. For example, a single dynamic volume may actually be made up of storage space on two separate hard disks. Also, dynamic disks can duplicate data among two or more hard disks to guard against the chance of a single disk failing. This capability requires more hard disks, but improves reliability.
