How Data Recovery Works

Losing your valuable data, either by damage to your computer or accidental deletion, is an upsetting experience.

Whether the lost files contain sensitive personal information, treasured photographs, or data for your business, the loss can be devastating.

Your data doesn’t have to stay lost, however.

Data recovery services specialise in restoring files that most people wouldn’t think would be recoverable.

 

Why Data Recovery is Possible

The files stored on your computer are all written onto the hard drive, which consists of thin, round platters coated with a shiny magnetic data storage medium.

A head inside your computer’s hard drive reads and writes the data onto the magnetic storage medium.

When you delete a file on your computer (or any type of device that stores data  including phones, tablets and portable memory sticks etc), it is not actually erased from the device.

The device simply changes the marker on that space from “occupied” to “vacant.”

The data itself is still there until it is written over.

However, the more times an old file is overwritten, the more difficult it will be to retrieve it – so the sooner you contact a data recovery service provider, the better.

What the Data Recovery Service Does

When you contact a data recovery service, usually the first thing we will ask is how the files you want to recover were lost.

You might have accidentally deleted the files, or the data might have become corrupted.

In a worst-case scenario, your media might have sustained damage, from software damage such as device crash, to serious physical damage such as flooding or fire.

Before the data recovery service begins work on your device,an exact copy of it is made.

All work will be done on this copy, to make sure no more damage is sustained to the media itself.

Using the copy of the original device, we deploy a variety tools and techniques to recover the lost data.

Devices create an equivalent of table of contents at the very beginning of the device.

By retrieving old tables of contents,we can ascertain where the files you need would be located on the drive, making it easier to identify the file type (document, spreadsheet etc), locate the overwritten file(s) and restore them to their former glory.

Once the data has been restored from the device, we check to make sure the files that have been recovered are complete.

 

Conclusion

Because of the nature of a hard drive or another type of memory storage, data loss is far from permanent.

However, don’t forget that when your valuable data has been deleted, lost, or damaged, time is of the essence if you are to get it back: The longer your computer runs, and the more often it writes to the hard drive, or the more often you use your phone or tabletthe worse the situation will get.
