Editor’s notes: Just like formatting a PC hard drive, formatting a DVR hard drive results in losing all the surveillance videos along with crucial digital evidence. As a professional DVR forensic solution provider, SalvationDATA has received countless similar cases over the years. Because of the diversity of all the different DVR manufacturers, it is pretty common that an operator may sometimes format or initialize the DVR hard drive by mistake. In this article, let’s see a practical solution to recover surveillance videos after formatting a CCTV DVR hard drive.

What is disk formatting?

Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. Disk formatting is sometimes also called disk initialization for DVRs. A disk formatting or initialization process would clear all file directories you have on this drive before and would re-write the file system structure. This results in a total loss of all surveillance data stored on this drive.

However, from the point of view of a professional forensic data recovery solution provider, the raw data of the surveillance videos are not wiped, and still are recoverable.
