How does Data Recovery WorkThere are a few different methods people use to recover lost data from hard drives. According to Computer Fixperts, a hard drive data recovery service in Brisbane, what method you need to use to recover lost data usually depends on how the data was lost in the first place. Most people don’t know this, but when you delete a file, it actually stays on the hard drive until you overwrite it with another file. So acting fast in this kind of situations can give you the advantage of finding your lost or deleted files. You need to be extremely careful when you accidentally delete some important file. Even the smallest things you do on your computer can result in you overwriting the file and that way it will be lost forever. Things like browsing the internet can result in overwriting your file because when you are using a browser it will create cookies and store cache. The last thing you want to do is to lose your files and documents because of cookies and cache.

When you install a software for the file and data recovery, you are risking to overwrite the lost files with the installation. The safest thing to do if you don’t want to backup your system is to have some software for data recovery installed to avoid the risk of overwriting the lost files.

 How to recover data

In the case you accidentally delete your file, you can use a recovery software such as TestDisk. This software uses complex algorithms that search for small pieces of information that are left on the hard drive after deletion, in order to know where exactly the file was located physically. If the software finds the right location, there is a high chance you will get the lost files back from the hard drive. Windows NTFS file system saves the file description information after the user deletes a file. That makes it easier for recovery software to find the files using that information. Systems like FAT and UTF, delete much more information about the file when deleting and because of that recovery software have a more difficult job to find the location of those files on the disc.
