How to Read Write Hard Drive Computer BIOS Firmware to SPI Flash Memory w/ CH341a Programmer NoMusic

Similar to computers, tablets, and smartphones, hard disk drives require instructions describing exactly how to boot. For hard drives, this data on how to boot is stored on 8-pin Flash memory chips and is accessed using the Serial Peripheral Interface (SPI) protocol.

During the Data Recovery process, it is often wise to both inspect and make backup copies of drives' boot firmware. Once saved, hard disk firmware can be copied (programmed) to other Flash Memory Chips and can be reprogrammed when firmware data loss is suspected or confirmed.

The CH341a Mini Programmer is an inexpensive tool for reading and writing directly to Flash memory chips using both the SPI and IC2 communication protocols.

When combined with AsProgrammer software available for free on GitHub.com:

Firmware can be save to and loaded from Microsoft Windows .BIN Binary Files:

This video illustrates how to use the CH341a Mini Programmer in conjunction with the free AsProgrammer software to both read and write to hard disk drive and computer SPI Flash Memory Chips.
