Abstract: An information handling system includes an optical disc drive. The optical disc drive is connected to an auxiliary power source so that a drive tray of the optical disc drive can be opened or closed, or a disc inserted or ejected from the optical disc drive when the information handling system is in a low-power mode. In response to these actions in the low-power mode, information is stored to record that the drive tray has been opened or closed. Accordingly, when the information handling system returns to a normal mode, it can take appropriate action, such as dismounting a logical volume associated with a disc that was previously in the drive. Because the optical disc drive can be physically accessed in the low-power mode, the information handling system does not have to enter the normal power mode in order for discs to be retrieved or inserted.

Abstract: A computer system and method includes a computing device and an optical drive. The optical drive is accessed by the computing device to provide information. The information describes the optical drive's write capability, whether the drive executes a pre-determined write strategy, and a digital data extraction capability of the optical drive according to a pre-determined format. The system utilizes a program configured by the computing device in response to the information provided, whereby the computing device operates supporting features of the optical drive, and supports a variety of optical drives without relying on a list of supported optical drives in a static drive table.

Abstract: A computer-readable medium device includes apparatus and a computer-readable medium. To a computing device, according to a predetermined command set behavior of the computer-readable medium device, the apparatus outputs a description of first and second features of the computer-readable medium device. The first feature is other than an identification of the computer-readable medium device. The second feature is an indication of whether the computer-readable medium device executes a predetermined write strategy. From the computing device, the apparatus receives a signal. In response to the signal, the apparatus accesses the computer-readable medium, according to the first and second features.

Abstract: An optical drive provides more rapid writes to an optical medium by analyzing defects detected on the optical medium to predict defect areas and avoid writes to the predicted defect areas until the defects are confirmed or refuted. For instance, a defect detector analyzes for a predicted defect if two or more substantially adjacent blocks of the optical medium are determined as defective by associating the determined defectives with a defect shape, such as a scratch, a fingerprint or a spot. The predicted defect is an area of the optical medium extended in the form of the shape in the direction of subsequent writes. The predicted defects are confirmed or refuted with test writes during an idle time, such as after completion of the write or in batches that make updates to a defect table more efficient.

Abstract: An information handling system (IHS) is provided that permits continued recording of a medium when a planned power loss occurs while the medium is being recorded in a media drive. If a low power condition is encountered during recording, the IHS saves location information regarding a last written block prior to the planned power loss. When power is restored, recording resumes at a location related to the location information.

Abstract: From a computer-readable medium device, a computing system receives a description of a feature of the computer-readable medium device. In response to the description, the computing system configures a program for managing access by the computing system to the computer-readable medium device. In response to instructions of the configured program, the computing system accesses the computer-readable medium device.

Abstract: An optical storage reconditioning module extends the life of re-writable optical medium, such as DVD+RW optical storage disks, by writing random information to recondition commonly used portions of the optical medium before re-writing information to those portions of the optical medium. For instance, a stored file system structure of an optical medium, such as a UDF random writable file system, is updated by reading to a buffer the structure from the optical medium, over writing the structure with random information recondition transitions between data points of the structure, updating the file system structure in the buffer and writing the updated file system structure over the random information.
