How does data recovery work?

19th August 2016

There are many reasons you might lose data from an SD card, a USB, or a hard drive. Perhaps the device has experienced a technical problem and the data has corrupted, or the device can no longer be recognised by your computer for you to transfer your files and photos across. Perhaps you made a mistake and deleted the wrong thing and can’t find a way to get it back.
Whether it’s important for professional or personal reasons, losing data can be very demoralising, but you don’t have to give up on those lost files. Data Resus is a data recovery service that can recover a vast range of file types from all sorts of media devices, whether they were lost by a simple mistake or by a bigger problem, be it a dropped hard drive or even water damage.

So how does Data Resus recover data?

Even if you think your data has been permanently erased, there’s a high chance it can be recovered. When you delete a file, for example, it isn’t removed from your computer straight away. Clicking ‘delete’ and removing a file from the Recycle Bin tells the computer that you’re not going to look at it anymore and you no longer care what happens to it. Consequently, the digital signpost saying where the file is and letting you access it gets taken away, and the space the data is located on the drive gets marked as accessible for future use without the user needing to be told it will be overwritten. Data Resus can find these files and essentially re-signpost them so they can be accessed again.

As you continue to use your computer, or any device you’ve deleted files from, the new data you create and store – even unintentionally, through temporary Internet files – starts to be stored in the space where your old files were. This space is often spread out over the drive, rather than all being in one area, so bits of the file may be replaced in only a matter of hours, while other parts might sit untouched on the drive for years. This is why recovery of some files is only partially successful.

It’s important, then, to minimise the use of a device you wish to recover data from as much as you can, as continued use of it provides more opportunities for the data you want to recover to be replaced with new data. One important example of this is downloading data recovery software; don’t download the software to the drive you want to recover from, if it’s a situation where the drive is still accessible, as you run the risk of replacing your data with the software.

The best thing you can do when you want to recover your data is stop using the device and contact an expert. Data Resus can be contacted by phone, email, or on social media, and we’re always happy to help. Let Data Resus help bring your data and memories back to life.
