## Title
Dock for a portable hard disk and a method for accessing content on a host device using the dock

## Abstract

There is provided a first dock for a portable hard disk, where the first dock is connectable to a host device. There is also provided a corresponding method for accessing content on the host device during use of the dock. It is advantageous that the host device is able to access content from portable hard disks that are docked with the first dock and a second dock.

## Background
FIELD OF INVENTION
This invention relates to both an apparatus for docking a portable hard disk and a method to access content on a portable hard disk using the aforementioned apparatus.
BACKGROUND
Both advances in technology and economies of scale have led to the downward trending price of a single unit of non-volatile storage memory. This decreasing price of non-volatile storage memory has led to non-volatile storage memory devices with voluminous amounts of storage capacity becoming affordable to even a non-corporate home user. This affordability has led to an increasing popularity of non-volatile storage memory devices with voluminous amounts of storage capacity.
Besides the increasing affordability of such non-volatile storage memory devices, one of the driving forces for the increasing popularity of non-volatile storage memory devices with voluminous amounts of storage capacity relates to the ease of creating and distributing digital content such as, for example, videos, photographs, presentations, and the like. In addition, an increasing number of people are converting their video/DVD collections into digital format for reasons such as, for example, ensuring longevity of their content, ensuring ease of accessibility to their video/DVD collection over a network, reclaiming storage space taken up by their video/DVD collection, and so forth. Such converted video/DVD collections typically also take up substantial amounts of storage capacity.
In view of the aforementioned, given the ease in creating and distributing digital content which typically takes up substantial amounts of storage capacity, it is evident that non-volatile storage memory devices with voluminous amounts of storage capacity are necessary to store the digital content mentioned in the preceding paragraph.
Unfortunately, voluminous amounts of digital content need to be managed in a proper manner in order to provide a favourable user experience. It would be undesirable if accessing the digital content was inconvenient for the user in relation to, for example, access time, locating of content, and so forth. Furthermore, storage of the content should also be robust to ensure longevity of the stored content. In this regard, it is evident that managing of digital content is essential when dealing with voluminous amounts of digital content.
In addition, it is also unfortunate that when a plurality of non-volatile storage memory devices with voluminous amounts of storage capacity are used, higher amounts of power are consumed as it is necessary for power to be drawn for each of the non-volatile memory devices. This is undesirable as content is typically drawn only from a single non-volatile memory device at any instance in time unless the plurality of non-volatile storage memory devices is set up in a RAID configuration.
The present invention aims to address the issues mentioned in the preceding paragraphs.
SUMMARY
In a first aspect, there is provided a first dock for a portable hard disk, where the first dock is connectable to a host device. The first dock includes at least one first connector for connection to another dock, the at least one first connector including both data and power connections; a processor coupled to the at least one first connector, the processor being for both controlling the first dock, and managing content of a portable hard disk docked to the first dock, where the managing of content includes synchronizing the content with the host device to shorten a time required to access content of the portable hard disk subsequent to docking to the first dock; at least one second connector coupled to the processor for enabling docking of a portable hard disk with the first dock, the at least one second connector including both data and power connections; and at least one third connector coupled to the processor for enabling connector of a second dock to the first dock, the at least one third connector including both data and power connections. It is advantageous that the host device is able to access content from portable hard disks that are docked with the first dock and the second dock.
Preferably, content from the portable hard disk connected to the first dock is accessed during the operational mode of the portable hard disk. Similarly, content from the portable hard disk connected to the first dock is not accessed when the portable hard disk is in a stand-by mode. Power consumed by the first dock may be lower during the stand-by mode. Preferably, the content relates to folders with movie files.
It is preferable that the synchronization of the content relates to data which enables the content to be indexed and searchable using a content management application running on the host device. The indexing may be carried out using parameters obtained from metadata from the content such as, for example, title, genre, thespian identity, director identity, producer identity, type of awards garnered, year of completion and so forth.
The managing of content may further include de-fragmenting the content on the portable hard disk subsequent to docking to the first dock to ensure that the content on the portable hard disk remains both accessible and undamaged.
It is preferable that the processor is able to send at least one signal to the host device to enable the host device to identify the first dock, where the host device is unable to access content through the first dock if the first dock is not identifiable. Preferably, the processor is configured to send the at least one signal to the host device only if contents of a portable hard disk docked to the first dock include a digital rights management (DRM) component. The processor may encrypt the content of the portable hard disk such that content of the portable hard disk is accessible only when the portable hard disk is connected to the first dock.
Both the at least one first connector and the at least one second connector may employ a connection such as, for example, USB, IEEE1394, SATA, Ethernet, any proprietary format and so forth.
The second dock may be mounted onto the first dock with a securing mechanism with interlocking parts on both the first dock and the second dock, with the securing mechanism being for ensuring both secure mounting of the second dock onto the first dock and an effective connection of the second dock to the first dock with the at least one third connector. The securing mechanism may be a robust hook-up mechanism. The first dock may be identical to the second dock.
It is preferable that the at least one first connector is able to connect to a third dock, the third dock being connected to a fourth dock in a second vertical column, the first dock connected to the second dock being a first vertical column, with the host device being able to access content from portable hard disks connected to the third dock and the fourth dock.
In a second aspect, there is provided a method for accessing content on a host device from a plurality of portable hard disk drives. The method includes connecting a first dock to the host device using a host connector of the host device; connecting a first portable hard disk to the first dock using at least one second connector of the first dock; mounting a second dock onto the first dock using a securing mechanism with interlocking parts on the first dock and the second dock respectively; connecting a second portable hard disk to the second dock using at least one sixth connector of the second dock; determining a mode of each of the first portable hard disk and the second portable hard disk, the mode being either operational or stand-by; setting the mode of each of the first portable hard disk and the second portable hard disk; and managing content of each portable hard disk by synchronizing the content of each portable hard disk with the host device to shorten a time required to access content.
It is preferable that content from each portable hard disk connected to each dock is accessed during the operational mode of each portable hard disk. Similarly, content from each portable hard disk connected to each dock is not accessed during the stand-by mode of each portable hard disk. Power consumed by each dock is lower during the stand-by mode than during the operational mode of each portable hard disk. The content may relate to folders with movie files.
The synchronization of the content preferably enables the content to be indexed and searchable using a content management application running on the host device. The indexing may be carried out using parameters obtained from metadata from the content such as, for example, title, genre, thespian identity, director identity, producer identity, type of awards garnered, year of completion and the like.
The managing of content may further include de-fragmenting the content on each portable hard disk subsequent to docking to each dock to ensure that the content on the portable hard disk remains both accessible and undamaged.
The method may also further include sending at least one signal from each dock to the host device to enable the host device to identify each dock, where the host device is unable to access content through each dock if each dock is not identifiable. Furthermore, the content of the portable hard disk may be encrypted such that content of the portable hard disk is accessible only when the portable hard disk is connected to either the first or second dock.
Preferably, the processor is configured to send the at least one signal to the host device only if contents of a portable hard disk docked to the first dock include a digital rights management (DRM) component.
Both the at least one first connector and the at least one second connector may employ a connection such as, for example, USB, IEEE1394, SATA, Ethernet, any proprietary format and so forth.
It is preferable that the securing mechanism may be for ensuring both secure mounting of the second dock onto the first dock and an effective connection of the second dock to the first dock with an at least one third connector. The securing mechanism may be a robust hook-up mechanism. The first dock may be identical to the second dock.
The method may also further include connecting a third dock to the first dock, wherein the third dock is connected to a fourth dock in a second vertical column, the first dock connected to the second dock being a first vertical column, with the host device being able to access content from portable hard disks connected to the third dock and the fourth dock.

DESCRIPTION OF PREFERRED EMBODIMENTS
Reference is made to FIGS. 1, 2 and 3 when describing a first aspect of the present invention. It should be appreciated that FIG. 1 provides an overview of an apparatus, and FIGS. 2 and 3 show applications of the apparatus during a first instance and a second instance respectively, and that details of the apparatus and application of the apparatus may differ in ways which would not substantially deviate from the present invention.
Referring to FIG. 1, there is provided a first dock 20 for a portable hard disk. The first dock 20 may be connectable to a host device. The host device may be, for example, a personal computer, a notebook computer, a network storage device, and so forth. The host device may be used for control of the first dock 20.
The first dock 20 includes at least one first connector 22, the at least one first connector 22 being for connection to another dock, with the at least one first connector 22 including both data and power connections. The at least one first connector 22 may be in a form which is retractable/extendible. The data connection of the at least one first connector 22 may be for transmission of data between the docks, where the first dock 20 is a conduit for the transmission of data from the connected docks (each dock being connected to a portable hard disk) to the host device. In addition, the power connection may be for transmission of power from the host device to each dock, and consequently, each portable hard disk connected to each dock. The at least one first connector 22 may enable a connection such as, for example, USB, IEEE1394, SATA, Ethernet, any proprietary format, and so forth.
The first dock 20 may include a processor 30 coupled to the at least one first connector 22, the processor 30 being for both controlling each portable hard disk connected to the first dock 20 to be in either an operational mode or a stand-by mode, and managing content of each portable hard disk docked to the first dock 20. The processor 30 may be able to send at least one signal to the host device to enable the host device to identify the first dock 20, where the host device is unable to access content through the first dock if the first dock 20 is not identifiable. The processor 30 may be configured to send the at least one signal to the host device only if contents of each portable hard disk docked to the first dock 20 include a digital rights management (DRM) component. The processor 30 of the first dock 20 may encrypt the content of each portable hard disk docked to the first dock 20 such that the content of each portable hard disk may only be accessible when each portable hard disk is connected to the first dock 20.
During the operational mode of each portable hard disk, content from each portable hard disk connected to the first dock 20 is accessed by the host device. Power consumed by the first dock 20 is lower during the stand-by mode of each portable hard disk than during the operational mode of each portable hard disk. This is because during the stand-by mode of each portable hard disk, the functionality of the first dock 20 is minimized as content from the portable hard disk connected to the first dock 20 is not accessed by the host device. It should be appreciated that having the stand-by mode for each portable hard disk aids in minimizing consumption of power by the first dock 20.
The managing of content of each portable hard disk docked to the first dock 20 includes synchronizing the content of each portable hard disk with the host device subsequent to docking of each portable hard disk to the first dock 20. Synchronizing the content of each portable hard disk with the host device may shorten a time required to access content from each portable hard disk. The managing of content may further include de-fragmenting the content on each portable hard disk subsequent to docking to the first dock 20. The de-fragmenting of each portable hard disk may ensure that the content on each portable hard disk remains both accessible and undamaged. The content may relate to folders with movie files. The portions of the content being cached may relate to data which is initially read when accessing the folders. In addition, the synchronization of the content may also enable the content to be indexed and searchable using a content management application running on the host device. The indexing of the content may be carried out using parameters obtained from metadata from the content such as, for example, title, genre, thespian identity, director identity, producer identity, type of awards garnered, year of completion and so forth. The content management application may include a graphical user interface which enables both ease of access to the indexed content and search-ability of the content.
The first dock 20 may include at least one second connector 24 coupled to the processor 30 for enabling docking of a portable hard disk with the first dock 20. It should be noted that during instances when there is more than one second connector 24, each second connector 24 may be connected to a portable hard disk. Each portable hard disk connected to each second connector 24 may either be stacked on another connected portable hard disk or placed adjacent to another connected portable hard disk. The at least one second connector 24 may be located within a first receptor 25 for the placement of the portable hard disk. The at least one second connector 24 may include both data and power connections. The data connection of the at least one second connector 24 may be for transmission of data from the portable hard disk to the host device, where the first dock 20 is a conduit for the transmission of data from each portable hard disk to the host device. In addition, the power connection may be for transmission of power from the host device to the first dock 20, and consequently, each portable hard disk. The at least one second connector 24 may enable a connection such as, for example, USB, IEEE1394, SATA, Ethernet, any proprietary format, and so forth. When the processor 30 detects that content is not drawn from each portable hard disk docked to the first dock 20, each portable hard disk connected to the first dock 20 is powered down to a stand-by mode.
The first dock 20 may also include at least one third connector 26 coupled to the processor 30 for enabling connector of a second dock 40 (in FIG. 2) to the first dock 20, the at least one third connector 26 including both data and power connections. The first dock 20 may be identical to the second dock 40. The at least one third connector 26 may be a proprietary connector. The proprietary connector of the at least one third connector 26 may be mate-able with an at least one fourth connector 28 which is also included in the first dock 20. A connection to the host device may be made using the at least one fourth connector 28. The at least one third connector 26 and the at least one fourth connector 28 may each enable a connection such as, for example, USB, IEEE1394, SATA, Ethernet, any proprietary format, and so forth.
The second dock 40 may be mounted onto the first dock 20 with a securing mechanism with interlocking parts 32(a), 52(b) on the first dock 20 and the second dock 40 respectively, the securing mechanism being for ensuring both secure mounting of the second dock 40 onto the first dock 20 and an effective connection of the second dock 40 to the first dock 20 with the at least one third connector 26. The securing mechanism may be a hook-up mechanism which is robust in design. The securing mechanism may also be for ensuring stability of a plurality of docks which are stacked on top of each other in a form of a vertical column such that the vertical column of docks is stable and does not topple.
When the first dock 20 is connected with the host device via the fourth connector 28, the host device is able to access content from each portable hard disk that is docked with the first dock 20. When the second dock 40 is mounted onto the first dock 20, the host device is advantageously also able to access content from each portable hard disk that is docked with the second dock 40. However, when data is accessed from each portable hard disk mounted on the second dock 40, each portable hard disk that is docked with the first dock 20 is powered down to a stand-by mode. A more detailed description of the second dock 40 being mounted onto the first dock 20 will be provided in subsequent paragraphs of the description.

In addition, the power connection may be for transmission of power from the host device 56 to both the first dock 20 and the second dock 40, and consequently, the second portable hard disk 54. When data is accessed from the second portable hard disk 54 mounted on the second dock 40, the first portable hard disk 34 is powered down to a stand-by mode. The at least one sixth connector 24 may enable a connection such as, for example, USB, IEEE1394, SATA, Ethernet, any proprietary format, and so forth. While only two portable hard disk drives 34, 54 are depicted in FIG. 2, it should be appreciated that more than two portable hard disk drives may be contemplated for the present invention.

Content on both the first portable hard disk 34 and the second portable hard disk 54 may be synchronized with the host device 56. Synchronizing the content of the first portable hard disk 34 and the second portable hard disk 54 with the host device may shorten a time required to access content from the portable hard disks 34, 54. Synchronizing the content of the portable hard disks 34, 54 also enables the content to be indexed and searchable, and power is managed on both the first dock 20 and the second dock 40 to minimize power wastage.
