Abstract
A data storage device (DSD) is disclosed comprising a SATA connector and control circuitry comprising a communication module for communicating with a host. At least one pin of the SATA connector is evaluated to detect a host type. When the host type is SATA, the communication module is configured to operate according to a SATA protocol, and when the host type is non-SATA, the communication module is configured to operate according to a non-SATA protocol.
Claims25
A data storage device (DSD) comprising a SATA connector and control circuitry comprising a communication module for communicating with a host, wherein the control circuitry is operable to:
- evaluate at least one pin of the SATA connector to detect a host type;
- when the host type is SATA, configure the communication module to operate according to a SATA protocol;
- and
- when the host type is non-SATA, configure the communication module to operate according to a non-SATA protocol.
A method of operating a data storage device comprising a SATA connector and control circuitry comprising a communication module for communicating with a host, the method comprising:
- evaluating at least one pin of the SATA connector to detect a host type;
- when the host type is SATA, configuring the communication module to operate according to a SATA protocol;
- and
- when the host type is non-SATA, configuring the communication module to operate according to a non-SATA protocol.
