Hard drive firmware is software that is embedded in the hardware of a hard drive and controls its operation. It is responsible for managing various functions of the hard drive, including controlling the drive motor, reading and writing data, managing power consumption, and handling error correction. Firmware of a hard drive is programmed by the manufacturer and is not typically user-modifiable. However, in some cases, firmware updates may be released by the manufacturer to fix bugs, improve performance, or add new features to the drive. Firmware can become damaged which may result in data becoming inaccessible.
