  • Non-intrusive replication of hard disk
    Patent number: 5960460
    Abstract: A computer program product embodied in a memory (FD1, FD2) implements procedures for replicating the contents of a first hard disk on a second hard disk. In a backup operation mode, the program enables a suspect computer (20S) to copy or backup sectors of its hard disk (22S) onto a temporary storage media (84) without recording on hard disk (22S). A user-designated signature, dimensioning parameters of hard disk (22S) and first checking information is also recorded on the temporary storage media (84, FD3). In a restore operation mode, the program enables a lab computer (20L) to read sectors of the hard disk (22S) from the temporary storage media (84) and to record sectors of first hard disk (22S) on the hard disk (22L) in accordance with the dimensioning parameters of hard disk (22S).

  • Replication of contents of hard disk to hard disk of greater storage capacity through adjustment of address fields in sectors
    Patent number: 5953744
    Abstract: Method, apparatus and program are provided for replicating an image of a source hard disk (22) onto a larger destination hard disk (22') in a manner that renders available the non-image-utilized sectors of the destination hard disk. Destination disk address dimensions are obtained from a drive (24') which handles the destination hard disk. Both source disk address dimensions and an image of sectors stored on the source disk are obtained from a temporary storage media (84). The image of the source disk is recorded on the destination disk (22'), but address values stored in the sectors of the image are adjusted to be based on the destination disk address dimensions rather than the source disk address dimensions.

  • Apparatus and method for CRC computation over fixed length blocks containing variable length packets of data received out of order
    Patent number: 5410546
    Abstract: The present invention discloses a method and apparatus for computing CRC codes for fixed length page buffers of user data where the user data arrives from a transmission device in variable length packets with the packet contents being out of sequential order. The received data is written to a storage device after being restored to the correct sequential order. The data packets are comprised of a header portion and a data portion. The transmission and compression methods commonly employed by the transmission device dictates that the header portion of each packet follows the data portion. The present invention computes a complete CRC code for the data stored in a page buffer in real time as the packets are received by using several registers for saving intermediate CRC codes and circuitry to combine partial CRC codes for those packet portions received out of order.
