Hard Disk Partition
Hard Disk Partition
When a large hard disk drive is used in the computer system, the best thing one can do is to partition it into several drives. The partitioning of the hard disk drives is a logical process. When the discussion of partitioning rages on; it strikes the mind that how can a hard disk be partitioned. It is not possible to partition a hard disk drive physically.
The logical partitions are usually created before the installation of the operating system. There exists some specific software that is capable of partitioning the hard disk drive after the operating system is completely installed.
The partitioning of the hard disk can be termed as important since it resembles that there are several drives that are connected to the computer system. Each partition in the computer can be treated as a single drive. The operations that can be performed over a hard disk individually can also be performed over an individual partition.
In short each partition behaves like single hard disk drive. The partitioning can be performed by the fdisk command in the DOS. The fdisk command lists a number of things a user can do. The first thing is that there is one and only one partition in any hard disk drive initially. The first thing is to select the option where the first thing is to make a primary DOS partition.
The Logical DOS partitions then follow. The primary DOS partition then should be set active. The disk integrity will be checked then and the user should select the space to be allotted to the primary partition.
After the user has selected the space allotment then the extended logical partition can be created. In the extended logical partition it is possible to create as many as possible partitions. Each of the partition should then be formatted. The formatting of the partition is necessary. The file system is also assigned to the partition.
The formatting of the partitions can also be done after the installation of the operating system. Unless and until the partitions are formatted they are unable to use. The formatting is necessary after the partitioning of the hard disk drive. The first partition is the primary partition which usually carries the name of the drive letter as ‘C’, the other partitions that follows are named as ‘D’, ‘E’ and so on up to the last partition.
The drive letter ‘C’ is used for the first partition because the ‘A’ is usually used for the floppy disk drive. The ‘B’ drive letter is used for the floppy disk drive of 5 ¼ inch floppy drive. This floppy disk and the drive and obsolete today, but still the drive letter ‘B’ is not used.
The CD drive and the DVD drive are allotted the name as the next consecutive letters after the hard disk drive. If the drive is to be partitioned after the installation of the operating system then the data may be lost some times. Hence a third party software should be used for the partitioning of the hard disk is the operating system is already installed already.
One example for the partitioning software is the ‘Partition Magic’. This software enables the user to even convert the file system with even harming the data that is tore over the hard disk drive.

Hard Disk Drive
Hard Disk Drive - In any computer system the hard disk is considered as the secondary memory device that is used for the primary data storage. The primary memory is obviously the RAM. But as the RAM is the primary memory it cannot be used for the purpose of the permanent data storage.
Hence a secondary memory device is necessarily needed for the purpose of the data storage in any computer system. Apart from hard disk drive the tape storage media can also be used as the secondary storage device. But the hard disk drive is the most popularly used secondary memory device. The main reason for this is the access speed and the reliability of the data it can offer. In the case of the tape drives the access speed is much low and the data transfer is comparatively low than the hard disk drive.
Since the primary memory that is the RAM is a non volatile memory hence it cannot be used as the permanent memory storage device. Hence the hard disk or the need for as a secondary memory device is needed in any computer. The primary function of the primary memory is to load the programs so that the CPU – Central Processing Unit can easily and speedily access and execute the instructions.
The primary memory can only boot the computer system, but it the hard disk drive that is responsible for the loading and the proper functioning of any operating system. The operating system is a necessary for the computers to run to the expectations of the user. Hence the hard disk is a must for the loading of the hard disk drive. The importance of the primary memory is that it is a compulsion that is necessary for the start up of the computer.
A computer can start up even with out a hard disk. But since there is no operating system that is present in the computer hence it is not possible to load the operating system. The computer will display a message usually in such a situation stating that “Disk Boot Failure”.
The information that is required to boot a computer is stored in the hard disk boot sector. Also the importance of the hard disk drive is to store the backup of the data or any information that is created by the user. Apart from the hard disk drives the other storage devices like the optical disks that are the CD ROM, DVD ROM etc can be used for the purpose of the backup of the data or user information. The floppy disks can also be used for the backup of the data. The hard disk specification should also match the expectations of the computers; that is the storage capacity and access speed.
The internal organization of the any hard disk drive consists of the following four parts primarily. They are as listed below: the Platters, the Head Arm, the Chassis, and also the Head Actuator.
The hard disk drive are also available in two different types that is the internal and also the external hard disk drive. The internal hard disk drive are used for the storage of the data in the computer case. There are not portable and usually are inside the case. The external hard disk drive are portable can be connected to other computer software systems as well. There is a hard casing over the hard disk.
