Abstract
Embodiments of the present disclosure provide for reading data from a physical storage medium, transferring the data between a data channel and a test interface over a parallel data bus, and providing the data from the test interface at a serial port in a serial format.
Claims20
A hard disk controller comprising:
- a data channel configured to read data from a physical storage medium;
- a parallel data bus;
- a test interface configured to (i) communicate with the data channel over the parallel data bus, and (ii) communicate with a testing equipment over a serial data link, wherein data read from the physical storage medium is transferred from the data channel to the testing equipment via (i) the parallel data bus, (ii) the test interface, and (iii) the serial data link, wherein each of the testing equipment and the serial data link is external to the hard disk controller;
- and
- a host interface configured to (i) communicate with the data channel over the parallel data bus, and (ii) communicate with a host device that is external to the hard disk controller, wherein the host interface is different from the test interface.

A software program embodied upon a non-transitory computer readable medium and operable to cause a disk controller to perform actions, wherein the actions comprise:
- reading data from a physical storage medium;
- transferring the data read from the physical storage medium between a data channel and a test interface over a parallel data bus within the disk controller;
- providing the data from the test interface to a testing equipment via a serial port in a serial format;
- communicating, by a host interface, with the data channel via the parallel data bus;
- and
- communicating, by the host interface, with a host device.
