Understanding Data Loss and Recovery

Exit Survey

With more businesses and consumers embracing big data than ever before, file recovery has become an ever-present way of life in the 21st century. However, it's impossible to understand the fundamental principles of data recovery without first understanding data loss.

What is data loss?
Data loss refers to the sudden or unexpected loss of digital information. Such data can be lost in a number of ways, including:
Logical: Often referred to as "user error," logical data loss occurs when a mistake is made by the user or the system itself. Mechanical: Sometimes known as physical failure, this is the result of some sort of hardware malfunction – usually within the drive itself. Electronic: Although electronic failures are easily confused with mechanical and physical failures, electronic failures are the result of a power surge or an improper electrical connection. These cases can typically be diagnosed by the telltale burning smell. Miscellaneous: Other occurrences can result in data loss, too. For example, an external hard drive or laptop that is dropped or damaged by water might experience the loss of data. Now that you have a better understanding of the different types of data loss, it's time to explore the various methods of data recovery.

What are the different types of data recovery?
Generally speaking, there are two different types of data recovery: logical and physical. In the case of a logical data recovery, the person performing the recovery is typically working with a fully functional hard drive or SD card. During a physical recovery, however, the affected medium is likely damaged and inaccessible via normal means.

Most logical data recoveries are easily performed with modern data recovery software. Additionally, there are many different third-party services that offer data recovery and restoration. However, depending on the type of damage, you might end up with a RAW partition that is inaccessible via your operating system or any other normal means. In this case, you'll have no choice but to perform a RAW data recovery.

Some of the symptoms of a RAW drive issue include:
.Frequent error messages, especially those pertaining to an unformatted or inaccessible disk.
.The volume of the RAW partition or drive does not contain a file system that is recognized by your operating system.

You can also check the drive's properties through your operating system to confirm if the file system is marked as RAW. In some instances, this can also be verified by the fact that the amount of free space on the drive shows 0 bytes.

If possible, avoid formatting a RAW partition – even if your operating system insists. Not only will this cause further damage to the RAW partition, but it might render you data completely inaccessible by any means whatsoever.

Now that you have a better understanding of the basic of data recovery, including some tips on working with RAW partitions, it's time to put your knowledge to good use and begin recovering your own lost files right away!
