What do you know about Hard disk , and what are the following Terms stand for and what do you know about them?

HDD (Hard Disk Drive) = Secondary storage, Fixed disk drive, 3.5-inch and2.5-inch, introduced in1956.

MBR  = Master Boot Record

EBR  = Extended boot record

VBR  = Volume Boot Record

Partation Table =  The permanent structure that informs the operating system or boot record how information on a hard drive is to be laid out.

Sector = A division of a storage medium on a hard drive

Cluster (block) = the smallest managed section of a hard drive that holds a file (file allocation unit )

Filesystems  = method of organizing and retrieving files from a storage medium such as a hard drive (FAT , GFS, HFS, NTFS, UDF)

RAID  = Redundant Array of Inexpensive Disks (RAID0, RAID1, RAID2, RAID3, RAID4, RAID5 etc.)

LVM = Logical Volume Manager (Linux)

Remap sectors  = Bad sector detection and recovery

 VSC = Vendor Specific Commands :

 LBA  = Logical Block Addressing

CHS  = Cylinder-head-sector

EXT4  = Fourth Extended File System (EXT4)

Filesystem jornaling = a file system that keeps track of the changes that will be made in a journal before committing them to the main file system.

SMART  = Self-Monitoring, Analysis and Reporting Technology.

Hard ( PATA = Parallel ATA, SATA = Serial ATA, SCSI = Small Computer System Interface)

 SSD = Solid-state drive

inode = An index node, informally referred to as an i-node, is a data structure used to represent a filesystem object, which can be one of various things including a file or a directory in a Unix-style file system,

Mounting filesystem = A filesystem is a way that an operating system organizes files on a disk, these filesystems come in many different flavors depending on your specific needs.

A Hard Disk Drive (HDD) is a data storage device used for storing and retrieving digital information.

Hard disk is the main part of computer like a brain in human body, all the data which are entered to computer stored in hard disk.

MBR master boot record

EBR extended boot record

File System are NTFS and FAT, Fat32 etc

VBR virtual boot record

Partition Table are associated with MBR which are most compatible to IBM and generaly used for other device to format the disk i many partition.

Sector the smallest unit of hard disk when need a low level format.

Cluster the smallest managerial unit of disk

Riad Duplicate array of inexpensive disk

LVM Logical Volume Manager

Remap Sector methed of removing bad sector

VSC Vender specific commands

LBA Logical Block addressing

CHS Cylender-head-sector

EXT4 fourth extended file system

Computer Management

HFS - Hierarchical File System

HFS+ Hierarchical File System Plus

These are2 formats used within Apple Hardware.

The Unix file system (UFS; also called the Berkeley Fast File System, the BSD Fast File System or FFS) is a file system commonly found within Unix.

I know that the Hard Drive is classified as the most mysterious piece of technology in Computer science :)
