1. A storage device with automatic interface-switching function comprising:
- a first interface connector comprising a first pin for transmitting a first voltage;
a hard disk for storing data;
a second interface connector coupled to the hard disk wherein the second interface is different from the first interface;
a first regulator comprising;
a first end coupled to the first pin of the first interface connector;
a second end coupled to a first power; and
a third end for outputting a second power when the first end of the first regulator receives the first voltage wherein the first regulator converts the first power into the second power; and
a first interface/second interface converting controller comprising;
a power end coupled to the third end of the first regulator for receiving the second power;
a first end coupled to the first interface connector; and
a second end coupled to the second interface connector;
wherein the second end of the first interface/second interface converting controller is high impedance when the power end of the first interface/second interface converting controller does not receive the second power;
wherein the first interface/second interface converting controller converts first interface data into second interface data.

Abstract
A storage device with automatic-switching function is disclosed. When the storage device is coupled to a USB interface, the power provided by the USB interface turns the USB/SATA converter on to convert data from the USB interface into SATA format and transmit to a hard disk. When the storage device is coupled to a SATA interface instead of the USB interface, the power provided by the USB interface does not turn the USB/SATA converter on to convert data. In this way, the data from the SATA interface directly transmit to the hard disk.
