Abstract: Bootability of a computer system with multiple LUNs. A flash device powers-on into a default LUN, from which the system boots, maintaining any other LUNs unavailable. The first LUN reconfigures the system to remove itself as the available LUN, to load a second LUN as the only available LUN, and to reboot the computer system into the newly available second LUN. The second LUN reconfigures the system to load any additional LUNs, such as removable storage on the flash drive. Upon reconfiguration, the system includes multiple LUNs. The second LUN includes an interpolated LUN driver, which exposes additional LUNs before operation of other device drivers. The interpolated LUN driver takes control during boot-up, exposing any available LUNs before the regular environment's operating system.

Abstract: Techniques for recovering from unexpected removal of (or other unexpected power loss) a flash memory device from a computer system. An interpolated device driver notes whenever the flash memory device is unexpectedly removed, or otherwise unexpectedly powers off or enters a locked state. If the flash memory device is reinserted, the interpolated device driver reinitializes the flash memory device, and satisfies any flash memory device security protocol, so the flash memory device and the computer system can be restored to their status just before unexpected removal. The interpolated device driver caches requests to the flash memory device, and when status is restored to just before removal, replays those requests to the flash memory device, so the flash memory device responds to those requests as if it had ever been removed. The computer system does not notice any break in service by the flash memory device due to removal and reinsertion.

Abstract: Booting an operating system that includes a secure preboot environment that performs integrity checks against security threats. A computer system boots to a preboot environment, which performs integrity checks and other anti-malware operations. Once the preboot environment finishes, the system reboots into a regular environment. The preboot environment can reside on a secure portion of a flash memory, with a computer system booting therefrom; or the preboot environment can reside securely in the computer system. The preboot environment includes integrity checks for a regular environment, and anti-malware programming. Once the preboot environment is done, the computer system reboots into a regular environment, such as from the flash memory or on the computer system. The integrity checks confirm that files in the regular environment are unchanged or uninfected. The integrity checks include determining the accuracy of a trusted system configuration on the computer system, such as using a TPM.

Abstract: A flash memory based storage device may utilize magnetoresistive random access memory (MRAM) as at least one of a device memory, a buffer, or high write volume storage. In some embodiments, a processor of the storage device may compare a logical block address of a data file to a plurality of logical block addresses stored in a write frequency file buffer table and causes the data file to be written to the high write volume MRAM when the logical block address of the data file matches at least one of the plurality of logical block addresses stored in the write frequency file buffer table. In other embodiments, upon cessation of power to the storage device, the MRAM buffer stores the data until power is restored, after which the processor causes the buffered data to be written to the flash memory under control of the flash memory controller.

Abstract: Systems and methods for storing and accessing data on a removable media having a changeable data set and an immutable data set. In one embodiment, a system can comprise a removable media storage system adapted to determine whether a host system running one or more applications is configured to enforce Write Once Read Many (WORM) policies. The host system can be communicatively coupled with the removable media storage system and configured to execute instructions causing the host system to determine whether to allow or deny a request to access data on the removable media. The host system can use rules to determine if an access request is to access data of a changeable data set or a immutable data set. If the request is to access data of the changeable data set, access is allowed. If the request is to access data of the immutable data set, reads are allowed, as well as writes of new data. Access requests to rename, delete, and/or write to existing data of the immutable data set are denied.

Abstract: A method for making memory more reliable involves accessing data stored in a removable storage device by translating a logical memory address provided by a host digital device to a physical memory address in the device. A logical memory address is received from the host digital device. The logical memory address corresponds to a location of data stored on the removable storage device. A physical memory address corresponding to the local address is determined by accessing a lookup table corresponding to the logical zone.

Abstract: The disclosure is directed to a method for creating a remnant magnetization on a magnetic tape medium. The magnetic tape is first substantially demagnetized, e.g., erased, by an erasure unit having multiple magnetic elements of alternating polarity. The erased magnetic tape is then passed by a bias magnet that creates a remnant magnetization on the magnetic tape. The remnant magnetized magnetic tape is then passed through a servo write head that writes servo patterns to the remnant magnetized magnetic tape. The bias magnet may be housed within the erasure unit or within a bias unit, and the distance between the bias magnet and the tape path of the magnetic tape may be adjustable to create the desired remnant magnetization on the magnetic tape. The remnant magnetization created on the magnetic tape may be greater than 20 percent to reduce defects in the servo pattern written to the magnetic tape.

Abstract: Embodiments provide systems and methods for maintaining immutable data in an archiving system using random access memory. To ensure data is immutable, novel pointers are maintained. For example, a modular drive bay maintains a pointer to a memory address in the removable drive memory cannot write data to a memory block that precedes the pointer. Data may only be stored after the pointer in the removable drive. As such, once data is written to the removable drive, the data cannot be overwritten although the removable drive employs random access memory.

Abstract: The present invention relates to a method and device for scanning of data for signatures prior to storage. First data are received at a storage device for storage therein. Upon receipt the first data are stored in a temporary storage medium for storing other than guaranteed previously scanned data. Using a processor of the storage device, the first data are compared with at least a predetermined signature and a comparison result is determined in dependence thereupon. In dependence upon the comparison result the first data are provided to the scanned data memory when the comparison result is indicative of other than a match or the first data are other than provided to the scanned data memory when the comparison result is indicative of a match. The method and the device according to the invention substantially reduce the risk that a file infected with a computer virus is transferred from one computer to another via a portable storage medium.
