ABSTRACT:
A computer-implemented method for installing a computer program from a removable data storage device using disk-mirroring techniques. The method includes the steps of mounting a removable data storage device containing the computer program as a read-only half of a mirrored logical volume identifying a fixed data storage device or hard disk drive as a read-write half of the mirrored logical volume; synchronizing the two halves of the mirrored logical volume by copying data from the removable data storage device to the hard drive; executing the computer program from the mirrored logical volume after an initial portion of the data is copied from the removable data storage device to the hard drive by the synchronization step and prior to a completion of the synchronization step; and removing the removable data storage device after the synchronization step is completed, thereby un-mirroring the logical volume. The removable data storage device may be a CD-ROM drive, floppy disk drive or tape drive.
