A disk drive system includes a disk drive controller system having separate head positioning and data transfer subsystems and supporting up to four disk drives, two of which may be removable and two of which may connect through a standard ST506 interface. The system provides a read and write protected cylinder for removably drive and a read only cylinder for removable drives which may store a unique serial number as well as other write protected data. Each removable disk drive may includes a register storing an identification code which may be used to control operation of the drive.

A disk drive system includes a disk controller system having separate head positioning and data transfer subsystems and supporting up to four disk drives, two of which may be removable, portable drive units and two of which may connect through a standard ST506 interface. The removable disk drives incorporate a read and write protected data cylinder for storing information such as the maintenance history of the drive, and a read only cylinder for storing a unique serial number as well as other write protected data. The system also features a high capacity, high speed sector buffer which allows continuous transfers of data to or from noninterleaved sectors and supports concurrent disk and system accesses.

A computer system includes a computer address modification system that is advantageously coupled in a bus network to selectively translate memory address data in 16K blocks and provide DMA page addresses which may match the 16K memory address blocks. The modification system includes a mapping RAM selectively providing translated addresses to enable addresses in a 1 megabyte address space to be selectively mapped to a 16 megabyte extended address space. The modification system also includes a page register storing for each addressable 16K block of data for each DMA channel a page address within the extended address space.

System and methodology are described that allow a new user of a user-operated device (e.g., wireless digital camera, cellular phone, video camera, audio device, or the like) to immediately begin using the features and services of the device without having to first activate a new user account. Thus in the instance where the user-operated device is a newly-acquired wireless digital camera, for example, the user can immediately begin taking and uploading his or her pictures to a photo Web site prior to having to open a user account, or having to perform other cumbersome activation steps. In such a wireless digital camera embodiment, the photo Web site and vendors of either cellular-enabled digital cameras or camera-enabled cellular phones provide user Web accounts based upon the unique ID or phone number belonging to one of these two devices. The user need only bother to “open” his or her account, that is, establish a user name and password, at some subsequent point in time that is convenient for the user (e.g., when the user is first visiting the photo Web site, using a browser, to view the digital photographs he or she previously uploaded). This approach allows users to use his or her newly-acquired device (e.g., immediately take pictures and upload them to an account at a photo Web site) right “out-of-the-box,” all without having to first register or setup a new user account.

A methodology for providing FTP-like server capability to a portable, intermittently-connected device, such as a digital camera device, is described. Using XML syntax, a photo-serving protocols suite supporting FTP-like photo-serving capability is incorporated into a digital camera device (or other portable device), so that digital images (or other files) on that device may be easily accessed by a variety of disparate hosts over standard protocols. If desired, standard (e.g., generic) FTP may be employed instead of the photo-serving protocols. All hosts that are commonly available include implementations of industry-standard TCP/IP protocols on which the photo-serving protocols may be borne. As a result, no host need have a proprietary, one-off solution to bear the photo-serving protocols. The camera device, at the level of the photo-serving protocols, functions in an identical manner no matter what host the camera device is attached to, and no matter how an individual industry-standard protocol suite is borne or implemented. In this fashion, a variety of host devices can access digital photos (or other files or objects) on the camera device with the same ease that a desktop computer may access files from an FTP server, for purposes of receiving or manipulating photographic image information captured on the digital camera device.

A method facilitating the transfer of information from a media or data capture device to a larger device while providing valuable feedback about the transfer is described. A transfer device including a simple user interface that can be easily implemented on a media or data capture device provides feedback about the transfer operation, enabling the user to take action when necessary. For example, the user is advised if the transfer is complete or, alternatively, that the transfer has failed and needs to redone. Feedback is provided by visual signals and may also be accompanied by audible signals. All necessary transfer functionality is included on the media capture device, thereby avoiding the requirement for dedicated software on a host (or pipeline) device, such as a cellular phone. This expands the number of pipeline devices that can be utilized with particular media capture devices. As long as there is a correct interface between the data capture device and the pipeline device, all the necessary transfer functionality can be included in the data capture device.

A system providing methodology for the restoration of original media quality in messaging environments is described. In one embodiment, for example, deployed in a messaging system, a method of the present invention is described for restoring media items to original quality, the method comprises steps of: upon receipt of a message containing an original media item that is new, storing the original media item in a repository; generating an identifier for identifying the original media item stored in the repository; replacing the original media item in the message with a substitute copy that includes the identifier; and upon future encounter of a particular media item having the identifier, restoring the particular media item to original quality using the identifier.
