Abstract
Various techniques are provided for interfacing external devices with host computer systems. In one example, hard drive parameters may be retrieved from a nonvolatile memory of an external hard drive enclosure device in order to register the external device with a host device while the host device provides a low power level to the external device. Following registration of the external device, the host device may provide a high power level to the external device to operate the registered external device. The hard drive parameters may be stored in the nonvolatile memory by a provider of the external device. In another example, the hard drive parameters may be loaded into the nonvolatile memory by appropriate software running on the host device. In yet another example, the external device may read the hard drive parameters from the hard drive while emulating another external device.
