The process, apparatus, and system estimate the size of a data block in a data buffer to efficiently recover the data block to the memory of a computer. The data block resides in a data buffer prior to being written to a destination medium. If the data block cannot be written to the destination medium, the process, apparatus, and system create a data block size estimate. The data block size estimate may be based on the size of the largest data block in the data buffer. Alternately, the data block size estimate may be based on the size of a data block in the memory of the computer. The computer reserves a memory space proportional to the data block size estimate and recovers the data block to the memory space.

Provided are a method, system, and article of manufacture for receiving an initial request from a first device to a second device. A response to the initial request is received from the second device to the first device. Each response and request received from the first device to the second device is processed by accessing the response or request from a packet encoded using a first communication protocol; generating a packet including the accessed response or request into a packet encoded using a second communication protocol; and transmitting the generated packet to the second device. Each response and request received from the second device to the first device is processed by accessing the response or request from a packet encoded using the second communication protocol; generating a packet including the accessed response or request into a packet encoded using the first communication protocol; and transmitting the generated packet to the second device.

A fast-acting method of regenerating track crossing signals for track searches across unrecorded areas on read/write optical discs is provided. This is accomplished by comparing the in-phase and quadrature-phase track crossing signals generated by the optical pickup head when a track search is being performed. A blank signal is generated when no quadrature-phase signal transition occurs between two successive in-phase signal transitions. Fake quadrature-phase signals are continuously generated. Upon occurrence of a blank indicating signal, the fake quadrature-phase signals are immediately supplied to the track crossing counter mechanism in place of the missing quadrature-phase signals. As a result, there is no loss of track count.

A computer-implemented method includes identifying a computer storage environment comprising a primary storage device and one or more secondary storage devices and determining a secondary data retrieval scenario associated with one of the one or more secondary storage devices. The computer-implemented method further includes determining a read-only retrieval arrangement based on the secondary data retrieval scenario. A corresponding computer program product and computer system are also disclosed.
