A system and related methods for characterizing and improving optical drive read performance is presented. The system includes an innovative audio file stored on optical media (characterization file), and an optical drive characterization agent, implemented on a computing system. The optical drive characterization agent iteratively controls the optical drive to perform incremental reads of at least a subset of the characterization file, analyzes at least the subset of the characterization file read from the optical media, and generates one or more performance scores on an associated one or more performance attributes of the optical drive. In this regard, optical drive characterization agent quantifiably characterizes an optical drives ability to accurately read individual sectors from optical media comprising audio content.

A method and system allows a device driver to obtain the status of a device that may exhibit one of two distinct behaviors in responding to status requests that designate a plurality of event types associated with a device. Devices exhibiting the first behavior respond to the status requests by providing the status for the highest priority event type designated in the status request. Device exhibiting the second behavior respond to the status requests by providing the status for the highest priority event type that has undergone a status change. In one implementation, the device driver transmits a series of distinct status requests such that the status of all event types can be determined. In a related aspect of the invention, the device driver also analyzes the response message to determine if the device exhibits the second behavior type. When the second behavior type is detected, only a single type of status request is sent to obtain the status of all event types.

The present invention prevents data underruns within an internal buffer of an optical media recording device while improving a recording rate by dynamically determining a time period to delay transferring data from a computer system to an optical media recording device. The time delay period may be set when an indication to delay data transfer from a source to an optical media recorder is received because the internal buffer is unable to hold or to receive additional data. The time delay period may then be set to a time less than a total time to empty the internal buffer given the total capacity of the internal buffer and the data transfer rate of the optical media recording device. Other factors also may be considered, such as the size and time for a single write to the optical media recorder.

A system that facilitates the storage of data using a write barrier. The system interfaces to a hardware component that stores data, and includes a write barrier component that dynamically employs instructions compatible with the hardware component to ensure data integrity during storage of the data. The write barrier component is independent of at least an operating system and an application and can operate in a least one of a user mode and a kernel mode. The write barrier component includes at least one of software instructions, routines, and methods, the selection of one or more of which is based on hardware data extracted from the hardware component. A selection component interrogates the hardware component for hardware data to facilitate selection of one or more instructions most suitable for interfacing to the hardware component. A coalescing component combines cache synchronization requests into a single set of instructions, which set is processed to flush a disk cache in one process.

Systems and methodologies that enable restoration of data by software solutions and in the absence of a hardware RAID adapter, via encapsulation of a RAID (Redundant Array of Independent/or Inexpensive Disks) format, by employing a Globally Unique Identifier (GUID) Partition Table (GPT). Third party vendors can employ proprietary data recovery software to access the raw data in case of malfunction of an associated RAID adapter. Moreover, the subject invention can facilitate inter-operability among a plurality of RAID adapters, to move array sets from one controller type to another.

An application on a computing device to write data to a storage medium associated therewith. The data is to be written to a secure storage area associated with an object on the storage medium, and the secure storage area has a value storage area associated therewith. The application generates a nonce and employs a shared session key (KS) to encrypt the nonce to result in (KS(nonce)). The storage medium receives same and decrypts with (KS) to result in the nonce, locates the value storage area associated with the secure storage area, and stores such nonce in the located value storage area. The application employs the nonce to generate a key (KH), encrypts the data with (KH) to result in (KH(data)), and sends same to the storage medium for storage in the secure storage area. Thus, (KH(data)) is associated with the nonce in the value storage area.

A method includes issuing a digital certificate to a licensee, the digital certificate identifying a licensed product and the licensee to enable the licensee to enable the licensed product. The method involves receiving a request to enable the licensed product from an entity, the request including the digital certificate and determining whether the entity is the licensee of the licensed product based on the digital certificate. A system includes a relational structure having associations among authorized entities and digital certificates within an organization. Each to digital certificate identifies a licensed product licensed to the organization. A certificate distribution module distributes the digital certificates to associated authorized entities.
