Data loss can turn into a big problem especially for employees and companies. Issues such as accidentally deleting or formatting have always been among the problems, but today we are also open to new dangers over the network and internet connection.
There are many services for recovering data that has been corrupted or accidentally deleted. None of these claim to 100 percent recover your data, but thanks to advances in recovery technology, the situation is better than before.
In this article, we will explain how different types of recovery software work.
Types of Data Loss
Data loss can sometimes occur due to sudden software or hardware problems, user errors, or hacker, virus, or malicious attack. The main reason data is suddenly corrupted is, power failure. Failure to properly remove removable drives can also cause damage.
Perhaps the most common cause of unexpected data loss is accidentally deleting files. Fortunately, it is possible to recover data in such errors, depending on the operating system used.
However, recovery software often cannot recover data lost due to hardware problem or damage. In this case, you need the help of data recovery experts for the damaged hardware.
How Recovery Software Recovers Lost Data?
How recovery software will recover data depends on the cause of the data loss and how much the files are damaged. Fortunately, a 100 percent data loss is rarely encountered, and you can often recover some data.
Exceptions here are overwritten data and unsaved documents. In these cases, you are probably not likely to see your data again. If you pay attention to software that claims to recover such data, it would be useful to approach it.
Minimizing Data Loss
When you notice data loss, the most important thing to do is to stop using the device with the data loss. This will prevent the data from being overwritten and unrecoverable. By disconnecting the device from the network and the internet, you should also avoid the risk of corrupted data being overwritten with intact data in other locations.
After that, run the data recovery software in no time. Doing so will give you the best chance of recovering critical data.
If the data loss in question is due to accidental deletion, the data recovery software will use a number of algorithms to locate the deleted files and then attempt to recover as much data as possible. The success of data recovery will depend on the file system used on that particular device.
Recovering files on the Windows NTFS file system (most end-user systems with Windows 10 use NTFS) will usually be easy. This is because NTFS does not delete files until they are overwritten. Therefore, if you stop using the device, the risk of overwriting the deleted data will decrease and the success rate will increase.
Similarly, you have a good chance of recovering data in ApFS file systems used in macOS.
You are less likely to recover on other file systems. File recovery in BSD UFS is almost impossible while you still have a chance to recover on the FAT file system.
Formatting the File System
Here, too, success depends on the file system used. You are likely to recover files on a disk that was reformatted as NTFS and was previously NTFS. This is because allocation information, directory registries, and filenames often remain on the disk and recovery software can rebuild the file using them. The same is true for ApFS.
You probably won’t be able to recover data from a disk formatted as FAT or BSD UFS.
File System Damage
The success of data recovery in this type of damage naturally depends on the extent of the damage. If the integrity of the file system is preserved, you will likely be able to recover a significant portion of the data. However, if the file system is severely damaged, it may take serious work to recover any file.
