Data recovery refers to accessing logically or physically damaged data or over written data without the use any functioning backup. The advanced data recovery has two different methods where the first method - Part replacement deals with the recovery from physically and or logically damaged data. In case of physical and/or logical damage usually the drive electronics or the system information gets altered from the normal values setting these to the previous sates or replacing the electronics or system information with certain values that can be matched with almost all such values of any specific dive is enough to recover the data.
The methods and challenges are discussed for replacing, or refreshing firmware and system area information and for replacing all or some part of the drive electronics. The second method of data recovery the Magnetic recovery deals with the recovery of the over written data.
The magnetic recovery uses the Magnetic Force Microscopy for recovery of over written data. The backbone of the magnetic recovery is the interesting fact that the magnetic memory always remembers whatever is written on it till it is forced for a degauss under strong magnetic field. The method of recovery using Magnetic Force Microscopy and its challenges are discussed. As far as the cyber forensics is considered the recovery of data after physical damage and over writing is of great importance. The most common methods of deletion and recovery using the journal are discussed along with the challenges.
The indomitable and invincible spirit of human being paved the way to the advent of computer systems. The seemingly impossible and boring tasks to mankind were implemented relentlessly through the computers. Human beings became the crown of all creations on earth through the various advancements achieved through his hard work for which the computers were also responsible. From a meager position of a data storage and calculating device, the computers emerged soon as the glorifying aid which took mankind to the heights of development. All those facilities provided by the computers made the man roll in riches. The increasing needs and pace of life demanded much needed advancements to the computer world. In the sphere of data storage, data recovery became important.
Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as hard disk drives, storage tapes, CD's, DVDs, RAID and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.
The loss of data can be due to logical and physical damages or due to over writing of data. And there are different ways to tackle all these three conditions. Go through the attached report for design and implementation of Advanced Data Recovery.
