If you own a computer or laptop, there is a probability that you may experience the hard drive failure. The reasons may vary from person to person. Accidental deletion of important files, damage from water, hard drive power failure or damage caused by some virus or malware, etc. In many cases, data recovery is possible. If you continuously heard a scratching sound in your hard drive, you can use data recovery software to recover the files.
Importance of Data Recovery
If you experience the data loss due to aperture arm failure in the hard drive or any damage in the platters, then it might be possible that you are unable to recover the data by using the software. In these cases, you might need to go to a data recovery technician.
No matter what the size of the hard disk is, you can recover the lost data. You can recover the lost data even if you delete the file from the recycle bin. The data that has been lost somewhere on the disk can be recovered as well.
Data hijacked or encrypted by ransomware (A type of malware) can also be recoverable in some cases. Actually, the ransomware could not encrypt your original files. It creates the encrypted copies of your files while deleted the original files.
You can retrieve those deleted files but you need to go to a data recovery technician. In case the ransomware deleted and then overwrite your files many times, then it might be impossible to recover the data and you might need to pay ransom to get back the copies of the original files created by the ransomware.
Data can be recovered from any operating system whether it is Windows or Mac and from any hard disk format or filling structure including NTFS and FAT32.
If you have multiple hard drives in your computer, RAID configuration can also be retrieved. If a single hard drive on the RAID configuration fails, the RAID setup will blot up the damage and there will be no data loss.

It depends on how many times the data is overwritten. If the data you want to recover is overwritten many times (more than 10 times) it will be very difficult to recover it back even if the lost data is not too old. On the other hand, if the lost data is not overwritten than it is possible to recover it even if it is lost 3 or 5 years ago.
