  Hard Disk Partitions refers to the creation of  logical drives  for effective memory management and a partition is the logical drive for storing the data. Hidden partition created on a drive can hide the data. The inter-partition gap is the space between the primary partition and the secondary partition. If the inter-partition drive contains the hidden data, use disk editor utilities like Disk Editor to change the information in the partition table. Doing so will remove all the references to the hidden partition, which have been hiding it from the operating system. Another way of hiding the data is to place the  digital evidence  at the end of the disk by declaring a smaller number of bytes than the actual size of the drive. Disk Editor allows  investigator  to access these hidden or vacant areas of the disk. The partitions are of two types: Primary partition:  it is the drive that holds the information regarding the operating system, system are...

  Understanding Bit, Nibble and Byte in this article explained  Bit , Nibble and Byte Data storage format of  hard disk  with how to calculate it. Bit A bit, short for binary digit is the smallest unit of data or basic information unit in  computing  and digital communications. It can contain only one of the two values represented as 0 or 1. They also represent logical values such as true/false, yes/no, activation states (on/off), algebraic signs (+/-) or any other two-valued attribute. Byte A byte, short for binary term is a digital information unit of  data  that consists of eight bits. The byte is representation of the number of bits a system has used to encode one text character. Therefore, it is the smallest addressable memory unit in many computer architectures. Two hexadecimal digits represent a full byte or octet. Nibble A nibble, also known as half-byte or tetrade is a collection of four bits or half of an octet in computing. Common repre...

  Tracks & Advanced Format of Sectors In this article explain hard disk track and diffrent andvance format of sector and there uses. Tracks Platters have two surfaces, and each surface divides into concentric circles called tracks. They store all the information on a hard disk. Tracks on the platter partition hold large chunks of data. A modern  hard disk  contains tens of thousands of tracks on each platter. The rolling heads read and write from the inner to outermost part of the disk. This kind of data arrangement enables easy access to any part of the disk; therefore, hard disks get the moniker as random access storage devices. Each track contains a number of smaller units called sectors. Every platter has the same track density. The track density refers to the compactness of the track circles so that it can hold maximum number of bits within each unit area on the surface of the platter. It also determines the storage capacity of data on the hard disk. It is a comp...
