How Does Data Loss and Recovery Work?

Data loss can occur from a hard drive failure, drive or data corruption, or accidental deletion of a file. Accidental deletion, software bugs, and hacking are common ways that you can lose data. To recover the data after it’s lost, it may take an act of God or a trained data recovery specialist who is skilled at retrieving data from storage.

Recovery isn’t always possible, but a professional can make it easier. The data-recovery technology has become extremely advanced. When a professional executes the task, most of the data from a hard drive can be recovered. For instance, an Australian company was able to recover 99 percent of the data lost when the space shuttle Challenger disintegrated at re-entry.

The Art of Recovering Data After File Deletion

Experts know that any file on a hard drive will remain on the drive until another file overwrites it. This is good news for recovery specialists who have a good chance of recovering a file. The most common file recovery software includes TestDisk. This software uses complex algorithms to sift through disparate pieces of information. The problem is that you only have so many chances to guess correctly or you’ll lose the file forever.

The Windows NTFS system will retain a lot of the information after the file has been deleted. This is why so many recovery specialists prefer NTFS systems. On the other hand, UTF and FAT systems are more likely to destroy information about the file after deletion. File-recovery algorithms will discover the “location of the file on the disk.”

How to Recover Data From a Corrupt File

A corrupt hard drive is a candidate for recovery, but sometimes, it can be difficult. It’s as simple as copying all of the data form one hard drive to another. The amount of data recovered will depend on the level of corruption.

Keep in mind that when you format a file system, information may be destroyed. The amount of data that’s erased will depend on the system format. Formatting with FAT may result in a large amount of data and rewriting section.

Be Aware of Data Recovery and How it Works

Recovery is one of the most impressive new types of technology available. It can help many companies avoid losing significant amounts of data and revenue from the down-time. Knowing about recovery is half the battle, you must also understand how to implement the software and avoid it in the future. If your drive is heavily damaged, for instance, this might be a task that’s best left to the professionals. They have clean rooms where they can take apart the drives and restore them to their normal and operational state.
