You can create a batch file on your portable USB drive named fix_hpa.bat containing:
An HPA is a hidden region of a hard drive or SSD that sits outside the standard operating system's visibility. Bad actors can exploit HPAs to hide malicious data, partitions, or covert tools. ATATool allows professionals to read, alter, or reset the HPA boundaries to reveal the drive’s absolute physical maximum sector capacity. 2. Device Configuration Overlay (DCO) Management
A typical usage scenario involved opening an elevated command prompt (Run as Administrator) on the target machine, navigating to the USB drive containing ATATool.exe , and executing commands like these: atatool portable

Bad actors and rootkits can hide malicious code, stolen files, or illicit data inside an HPA.
Running ATATool as a portable utility—such as within a lightweight Windows Preinstallation Environment (Windows PE)—provides an isolated, forensic-grade environment. This isolation prevents automated operating system writes from altering evidence on a target drive, making it a critical tool for deep hardware manipulation. What is ATATool?
