Importance of Data Recovery 

Data recovery is the process of retrieving corrupted, accidentally deleted, lost, or inaccessible data from storage media. The process usually involves recovering data from internal and external storage devices including hard disk drives (HDD), USB drives, solid-state drives, CDs, DVDs, floppy disks, magnetic tapes, memory cards, and other data storage devices.  

For almost every kind of business, data is an indispensable part. All business activities revolve around data. Therefore, ensuring the safety of information gathered over time is very important. Moreover, losing data whether on a personal or professional level can be traumatic. It is especially a cause of worry for business establishments because as per the statistics revealed around 72% of businesses that face critical data loss tend to shut down within 24 months. Hence, there is nothing more important than securing data.

In addition to this, data stored on devices supporting removable memory cards such as mobile phones or tablets can also be recovered using advanced techniques. 

Since such accidents are unpredictable and can happen anytime, organizations need to be prepared to deal with them. Data recovery should be part of every organization’s disaster recovery plan. Doing so will aid organizations to deal with data loss emergencies and get back to the track within a minimal downtime.

Benefits of Data Recovery 

Data recovery is beneficial in many ways. In corporate as well as personal life data recovery plays an imperative role.

Reasons for Data Loss  

Data loss can occur due to multiple reasons. It can also be caused by human error. However, depending on the type of cause data loss can be divided into two broad categories-

  • Physical Failure
  • Logical Failure

Physical Failure

Physical failure entails to a condition wherein the disk management system for windows or the Disk Utility system for macOS cannot detect the storage device. Component damage, connectivity complications, read/write failure, head crash, and bad areas in physical storage space all contribute to physical failure. In this kind of failure, the storage drive becomes inaccessible and requires the replacement of failed components using advanced tools & techniques. 

Reasons for physical device failure: 

  • Physical shock due to mishandling.
  • Power failures.
  • Mechanical damage.
  • Fire, thunderstorms, earthquakes, floods.

Logical failure

Logical failure occurs when your files become inaccessible due to the loss of reference files on your storage device. In these kinds of failures, the device remains physically active. The various factors that contribute to logical data loss include partition corruption, partition deletion, OS failure, drive formatting, and virus damage. In logical failures, along with your drive, unallocated space in Disk Management (Windows) or greyed space in Disk Utility (Mac OS) also becomes unavailable. Since the device in such failures remains active the data remains intact, therefore its further use should be immediately stopped to prevent data overwriting. This will increase the chances of successful data recovery. 

Reasons for logical device failure: 

  • File Directory Damage from a Virus or Malicious Program
  • Operating System Corruption
  • Accidental File Deletion 
  • Unintentional Formatting 
  •  Overwritten Data 

How Data Recovery works  

Data recovery helps you get back your lost data. But the chances of successful recovery majorly rely on the situation of data loss. However, it is quintessential to remember that it is nearly impossible to recover data once it gets overwritten. That’s why it is recommended not to write anything on storage until all files are rescued. 

Data recovery is possible because during formatting or deletion data is not removed permanently. Only the references of files are removed which render data inaccessible. Thus, using technical procedures it is possible to recover all your lost files and folders. 

Supported Devices for Data Recovery 

Data can be salvaged from almost any kind of data storage device irrespective of its make and model. The supported devices for data recovery include:

Data can be recovered from the above devices using different techniques. Every kind of device has a distinct data recovery process depending upon its configuration. 

Do and Don’ts once data loss  

In order to preserve your data and avert the risk of permanent loss, there are some basic steps that you need to abide by. Mentioned below is a list of dos and don’ts that you must follow as soon as the data loss mishap strikes. 

Have a look at these preventative measures: 

Do’s

  • Immediately discontinue the device use as further use may result in a worsening situation.
  • If you suspect any signs of damage or data loss, calmly assess them and make a note of things that have happened. Doing so will help you diagnose issues later.
  • On encountering unusual changes in system/ drive consider taking up backup immediately.
  • Properly assess all power and data connections to drive.
  • If your drive makes erratic noises of clicking or grinding, switch off the system instantly.
  • Restrict using the affected device so as prevent permanent data loss.
  • If data loss has occurred from external drive then verify it’s functioning by connecting it to another working system.
  • Determine the nature of data loss; check whether it is a logical or physical failure.
  • The most important action you need to take is to call a data recovery expert company.

Don’ts

  • Don’t try to use non-responsive or clicking disk forcibly.
  • Don’t tap or hit hard drive with force as it may lead to a head crash.
  • Don’t attempt to open hard drive, it can ruin device beyond repair.
  • Don’t use any data recovery software or files, it may destroy data permanently.
  • Don’t access the internet on the damaged system, because browsers save the cache to your disk.
  • Don’t attempt to use any DIY methods; it can potentially cause more damage.
  • Don’t try to heat OR freeze the hard drive, it can cause further damage and make data irrecoverable.

Recovery of Data from Formatted Hard Disk 

Formatting is done to remove all existing files and folders to provide a clean slate for new data. This is basically performed to clean up space in hard drive. But, unfortunately, sometimes you may become victim to accidental formatting which may prevent you from accessing your important files. This unintentional formatting issue can be alarming as it results in data loss. 

However, during accidental formatting, your data is not overwritten immediately. The system only marks the space as clear for the next information to be written over it. Thus, the chances of successful data recovery strongly depend on the amount of data overwritten in the disk. Besides this, some other factors that may have an impact on data recovery process include:

  • Hard drive size.
  • Operating system.
  • Size of the requested files.
  • Utility involved in formatting. 

Despite all, it is still possible to recover data from an accidentally formatted drive. To prevent overwrite data recovery professionals create a clone of your hard drive. This is done to ensure that all recovery processes are performed on a cloned drive while keeping your original drive intact.  

Recovery of Data from Broken Hard Disk 

Mechanical failures are attributed hold a large share for data loss. Since hard disk drives have extremely small components they are more susceptive to physical damages. These damages may affect the platters, read/write heads, and PCB.  However, when treating such issues use of advanced tools and techniques is critical.

Some of the most common signs of a broken hard drive include:

  • Unusual sounds of Clicking, Clunking, and Whirring 
  • Failure to spin during the bootup process.
  • Onscreen error messages.
  • The smell of burning electronics or solder.

To recover data from broken hard drives, specialized facilities such as Class 10 ISO 4 Cleanroom are needed. The Cleanroom prevents sensitive drive components against contamination, especially the read/write heads and platters. Furthermore, necessary firmware repairs are required to diagnose damaged components and thereafter data is moved to other devices to carry out logical data retrieval processes if needed.
