Data Recovery Software – Necessary or Not?

Data Recovery Software - Necessary or Not

Data is the most essential component for every individual and business. Data whether it belongs individual data or organisation’s data is very crucial as it contains confidential information which if lost, accidentally deleted, corrupted or formatted can lead to bug financial losses.

There might be situation where your confidential data accidentally gets lost, deleted, corrupted and formatted due to some human intervention or due to power failure. These data loss circumstances could lead to financial losses which sometimes can’t be reversible.

Data Recovery software are used to restore/recover any lost, deleted, corrupted and formatted. Today we are here to discuss whether data recovery software is necessary or Not.

Unistal is amongst the pioneer in data recovery software and services since 1994. Unistal has developed more than 40 products in the category of data recovery and is continuously working to develop more advanced data recovery software. Use of data recovery software is increasing at a rapid rate with the advancement in the technology and the number of data loss cases reportedly every minute across the world.

Data is always present in large storage devices which can get inaccessible either due to:

  • Physical Damage
  • Logical Damage

There are various failures which could cause physical damage to the storage device in which the confidential data is kept. Some of the reason of physical damage can be human errors and natural disaster. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer any of several mechanical failures, such as head crashes and failed motors; tapes can simply break. Physical damage always causes at least some data loss, and in many cases the logical structures of the file system are damaged as well. Any logical damage must be dealt with before files can be salvaged from the failed media. Most physical damage cannot be repaired by end users. For example, opening a hard disk drive in a normal environment can allow airborne dust to settle on the platter and become caught between the platter and the read/write head, causing new head crashes that further damage the platter and thus compromise the recovery process. Furthermore, end users generally do not have the hardware or technical expertise required to make these repairs. Consequently, data recovery companies are often employed to salvage important data with the more reputable ones using class 100 dust- and static-free clean rooms.

The term “logical damage” refers to situations in which the error is not a problem in the hardware and requires software-level solutions. In some cases, data on a hard disk drive can be unreadable due to damage to the partition table or file system, or to (intermittent) media errors. In the majority of these cases, at least a portion of the original data can be recovered by repairing the damaged partition table or file system using specialized data recovery software such as Testdisk; software like dd rescue can image media despite intermittent errors, and image raw data when there is partition table or file system damage. This type of data recovery can be performed by people without expertise in drive hardware, as it requires no special physical equipment or access to platters.

Data Recovery software will only recover data from logical damage storage devices.

There are two types of data recovery software:

  • Pre Crash Data Recovery Software
  • Post Crash Data Recovery Software

Pre Crash data recovery software is preinstalled in the computer system. The software takes the image of the index of file/folders present in the computer system at regular point of time and store it in some protected space which is used in case of any accidental data loss.

Post Crash data recovery software is installed in the computer system after the data has been lost. After installing the software, it takes the image of the index of current storage device and finds the space which is recently been free to be overridden by other data. It provides the user with the list of recently deleted data from which the user can select the data to be recovered.

That’s it in today’s discussion about “Data Recovery Software – Necessary or Not?”.
