A method and System for Providing an Industry Standard USB Port and Built -in
Support for Various Firmware on a Disk Drive
Currently, disk drive manufacturers are using Universal Asynchronous Receiver Transmitter (UART) serial port with limited firmware support for interfacing external tools with the disk drives. In addition, the external tools are required to use a non-standard cable and a unique firmware code for interfacing with the disk drives. Such use of the non-standard cable and the unique firmware code for interfacing the debug tool with the disk drives often becomes impracticable. For example, in a configuration containing many disk drives, a data corruption event may happen randomly on different disk drives. In such a case, it is desirable to have the debug tool attached to each disk drive in order to interpret log information pertaining to the data corruption event. However, debug tools may be expensive and attaching an individual debug tool to each disk drive using the non-standard cable and the unique firmware code may prove to be costly.
Therefore, in order to overcome this problem, a method and system is disclosed for providing an industry standard USB port and built-in support for various firmware on a disk drive. The provision of industry standard USB port on the disk drive along with its supporting firmware in the disk drive base code allows any industry standard USB cable or device (memory stick, etc) to be connected to the disk drive.
