The present disclosure relates generally to computer systems and information handling systems, and, more particularly, to a system and method for capturing and storing one or more failure errors of an optical storage drive and optionally, capturing media information, if desired.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to these users is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may vary with respect to the type of information handled; the methods for handling the information; the methods for processing, storing, or communicating the information; the amount of information processed, stored, or communicated; and the speed and efficiency with which the information is processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include or comprise a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
An information handling system may comprise one or more optical storage drives. The optical storage drives may be read-only, writable, or rewritable. Examples of optical drives include CD and DVD drives.
Optical storage drives may experience failure errors when reading or writing data to optical storage media. Diagnosing failures in optical storage drives may be problematic for a variety of reasons. Often, when a failure error such as a read or write error occurs, the associated error code may be reported to the operating system, and the operating system or software utility may inform the user of the failure error, but the details of the failure including the media information and failure error description may never be disclosed to the user or may never be stored for later use or diagnosis. Even when the failure error information is disclosed to the user, the failure error information may be too generic, not complete, and/or inaccurate.
Further compounding the problem of diagnosing optical storage drive failures is the lack of information as to the media used when the failure error occurred. Often, the media used is not returned with the optical storage drive to the manufacturer so the information relating to the media used may not be available to the manufacturer for failure error diagnosis.
In accordance with the present disclosure, a system and method is disclosed for the management and capturing of optical drive failure errors. One implementation of a method of capturing a failure error of an optical storage drive may include detecting the failure error of the optical storage drive. The failure error may be characterized by an error identifier, which may be stored in a drive memory. In certain embodiments, methods herein may also include storing media information available on optical storage media to the extent that such media information may be available. Additionally, some embodiments may include the detection and storage of a plurality of error identifiers. Systems implementing the methods herein are also disclosed.
Among other advantages, storage of error identifiers and/or media information may aid manufacturers in diagnosing problems with returned optical storage drives. Other technical advantages will be apparent to those of ordinary skill in the art in view of the following specification, claims, and drawings.
A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and wherein:
For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communication with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.
Optical storage drives may experience failure errors when reading or writing data to optical storage media. The failure errors are typically associated with or characterized by error identifiers, which may further describe the type of error experienced. In some cases, error identifiers may also be referred to as error sense codes. The number and types of error identifiers that an optical storage drive may experience are varied and numerous. Examples include error sense codes such as, 03/11 (unrecoverable read error) and 03/02 (seek error).
Optical storage media may include media information stored on the optical storage media. Media information may include any variety of information about the media and/or the manufacturer identity of the optical storage media. For example, in the case of pressed media, the media information may include manufacture media information, and in the case of recordable media, the media information may include embedded track information. Embedded track information may include ATIP (Actual Time in Pregroove) for CD formats, ADIP (Address in Pregroove) for DVD formats, or any other embedded track information. Depending on the particular optical storage media, the media information may or may not be available on the optical storage media.
Optical storage drives may have a drive memory capable of storing information or data. Often, at least a portion of the drive memory may be a nonvolatile memory. Although this nonvolatile memory may be intended for uses such as firmware updates, the methods herein recognize that a portion of this memory may be set aside for the purpose of storing error identifiers and/or media information.

At step 330, a determination is made as to whether the optical storage media is a pressed media or a recordable media. If the optical storage media is a recordable media, method 220 continues to step 342, storing the embedded track information in the drive memory. Embedded track information may include actual time in pregroove media information (ATIP) for CD formats, address in pregroove media information (ADIP) for DVD formats, or any other embedded track information. If the optical storage media is a pressed media, method 220 continues to step 346, storing the manufacturer media information in the drive memory. The manufacturer media information may include, for example, information relating to the manufacturer identity. Depending on the particular optical storage media, the media information may or may not be available on the optical storage media.
At step 430, a second failure error, which may be characterized by a second error identifier, is stored in the drive memory while retaining the first error identifier in the drive memory. As depicted in step 440, any second media information may be stored along with the second error identifier as well. The second media information may be the same media information as the first media information, for example, if the optical storage media is the same as when the first failure error occurred. In preferred embodiments, the first error identifier is retained in the drive memory after storing the second error identifier. Method 400 ends at step 499.
As used herein, the terms, “first” and “second” with respect to “first failure error” and “second failure error,” do not signify any absolute sequence among other failure errors, instead only denoting a relative relationship of the failure errors with respect to each other. That is, “first” does not mean prior to all other occurrences, but instead merely refers to being precedent to the “second” failure error. Likewise, the term, “second” merely indicates that the “second failure error” occurs at sometime after the occurrence of the “first failure error.”
As used herein, the term, “retaining in the drive memory” allows temporary erasure of the failure error and/or media information to allow rewriting the information to be saved depending on the particular type of drive memory and file system implementation used. Thus, the storing and retaining of a plurality of failure errors, as used herein, only requires that at least a plurality of failure errors experienced be stored for later retrieval by the end of a method.
A variety of drive memory types may be used with the systems of the present invention. In preferred embodiments, nonvolatile memory is used for the drive memory to allow storage of the error data without power. In certain embodiments, flash type memory is used for the drive memory. Because certain types of nonvolatile memory are limited to a finite number of write cycles before failure, a wear leveling write file system may be used in certain embodiments to spread out equally the data storage along portions of the drive memory. Additionally, in certain embodiments, the storing of data in the drive memory may be implemented using a first-in first-out (FIFO) stack implementation. A FIFO stack implementation allows the oldest data stored to be deleted to allow storage of the most recent failure error and/or media information in the event the capacity of the portion of the drive memory being used is reached.
As a person of ordinary skill in the art with the benefit of this disclosure would recognize, modifications, additions, or omissions may be made to the procedure without departing from the scope of the invention. The procedure may include more, fewer, or other steps. Additionally, steps may be performed in any suitable order without departing from the scope of the invention. Although the present disclosure has been described in detail, it should be understood that various changes, substitutions, and alterations can be made hereto without departing from the spirit and scope of the invention as defined by the appended claims.
