  • Clientless external storage device
    Patent number: 7363632
    Abstract: A method for installing an external storage device (such as a hard drive) to a computer is disclosed. The external hard drive includes a driver storage formed integral to the external hard drive. The driver storage stores the device driver information. Upon connection to the computer, the external hard drive's driver storage imitates a known disk drive to the computer. The computer can then access the device driver information and install the external hard drive.
    Type: Grant

  • System and method for installing portable device drivers
    Patent number: 7331051
    Abstract: A method for installing a peripheral device to a computer is disclosed. The peripheral device includes a driver storage formed integral to the peripheral device. The driver storage stores the device driver information. Upon connection to the computer, the peripheral device's driver storage imitates a known disk drive to the computer. The computer can then access the device driver information and install the peripheral device.

  • Snapshot facility allowing preservation of chronological views on block drives
    Patent number: 7055010
    Abstract: A method for efficiently maintaining snapshot instances. To maintain the state of snapshot instances, the snapshot copies the data needed to be protected into free space on the same volume. In order to identify whether a block is free, a snapshot record is created for each block on a volume to record write operations on the block. With these snapshot records, the allocation status of blocks on a volume can quickly be identified. Free space allocation is then accomplished by allocating free space via the file-system provided interface and identifying it with snapshot records. With this mechanism, snapshot software can allocate free space to store snapshot metadata and “copy-to-write” data dynamically.
