Abstract
Provided are systems and methods to communicate data transfer of data between a disk device and an external storage device. A host can generate a control command to communicate with an external storage device, and a disk device to receive the control command from a host to identify and communicate with an external storage device when connected to the external storage device and to configure the external storage device by assigning an ID code to each storage area of the external storage device.
Claims26
A system comprising:
- a host to generate a control command to communicate with an external storage device;
- and
- a disk device to receive the control command from the host to identify and communicate with the external storage device when connected to the external storage device and to configure the external storage device by assigning an ID code to each storage area of the external storage device.
A method comprising:
- receiving a command signal at a disk device from a host device to identify an external storage device and to assign ID codes to each storage area of the external storage device;
- and
- assigning the ID codes to the storage areas to configure the external storage device based on the identification of the external storage device.
A disk device comprising:
- a control part to receive a control command from a host device to identify an external storage device;
- a memory to store the control command and to generate a second control signal to assign ID codes to storage areas of the external storage device;
- and
- a switching unit to determine whether to transmit the second control signal to the external storage device to assign the ID codes to the storage areas therein.
A method comprising:
- receiving a command signal including ID codes of one or more storage areas of an external storage device at a controller from a host device;
- assigning the ID codes to the one or more storage areas to configure the external storage device;
- and
- transferring data between the controller and at least one of the one or more storage areas of the external storage device.
A method comprising:
- receiving a command signal at a controller from a host device to identify one or more storage areas of an external storage device;
- identifying the one or more storage areas with the controller;
- assigning ID codes to the one or more storage areas to configure the external storage device;
- and
- transferring data between the controller and at least one of the one or more storage areas of the external storage device.
A system, comprising:
- a controller to communicate transfer data between a host device and an external storage device, the controller configured to receive at least one ID code corresponding to at least one storage area in the external storage device, and configured to assign ID codes to a plurality of storage areas in the external storage device in response to a control command from the host device.
A system, comprising:
- a controller to communicate transfer data between a host device and an external storage device, the controller comprising
- a non-volatile memory configured to store ID codes for each of a plurality of storage areas in the external storage device, and
- a control unit configured to identify ID codes stored in the non-volatile memory, and replace at least one ID code with a new ID code in response to a control command from the host device.
