  • 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).
