: In digital investigations, ATATool is used to check for data hidden in HPAs, which can be a common tactic for concealing information from standard forensic imaging tools. Target Audience and Accessibility
Its purpose is to expose and modify hidden areas of a hard drive that standard operating system tools cannot access, primarily the and the Device Configuration Overlay (DCO) . An HPA is a hidden storage area on a hard drive that the BIOS uses to store system recovery tools or other essential code. The DCO is an even lower-level overlay that can be used to "clip" a drive's capacity. The tool can also be used to simulate and repair "bad sectors" on a drive.
