Is there a way to extract firmware from a device?
With physical access to the device, a technique for extracting the firmware is to directly read the device’s storage memory. We can identify and remove the memory chip from the board, solder it on another board and extract the firmware.
Can a Western Digital hard drive be hacked?
I found an old Western Digital hard drive in pretty good condition, so I unscrewed the controller and had a look. This is where I’d put my flash…if i had any.

How is firmware image stored in persistent memory?
JTAG is a physical hardware interface that makes it possible, among other things, to extract the firmware image from electronic devices. The firmware, a program that executes in a dedicated way and with a specific purpose in a microcontroller or microprocessor, is usually stored in a persistent memory device like a NAND/NOR flash or EEPROM.
How to extract useful information from binary file?
When analyzing binaries, it is important to be able to put what is observed into context. For example, how can CPU instructions be differentiated from data in a binary with a non-standard format?
Is there a way to regain access to firmware?
