#%C duplicates QNX hard drives.
#
# File: QNX_drive_copy
# Description:
#   This program creates logical copies of hard drives, as opposed to "dd"
#   image copies.  Therefore it does not rely on matching drive geometeries,
#   does not copy unused parts of the drive and the copy is defragmented.
#   This script assumes the drives use Logical Block Addressing (LBA) mode,
#   and are only one partition, and that partition is QNX of course.
#   Licenses and "bootability is preserved.  A log of is saved in /tmp/log.
# Keywords: duplicate hard drive disk copy image format master
# Version: 1.0
# Entered-date: 12-Jan-1998
# Author: Maurice Cinquini <cinquini@alamar-usa.com> of Philips DVS.
# Credits:
#   Robert Rutherford and Anthony Wei of Philips DVS,
#   with hints from Karl Heinz of Hughes, Soenke Nielsen
#   and the output of the QNX install process.
# Copying-policy: This program is public domain, but using this program
#   to distribute the QNX OS and other software requires permission from,
#   and/or royalites to, the legal owners of that software.
# Supplemental:
#   Only tested with QNX 4.24, single partition, LBA, IDE drives only.
#   The complete procedure to copy drives involves the following steps:
#   1. Insert the master (source) and slave (blank) hard drives.
#      Depending of the machine setup, slave drives usually needs to
#      have a jumper removed.
#   2. Boot QNX in a safe mode where there are no programs running that
#      may asynchronously write to the hard drive during the following
#      procedure.  If you can't guarantee this, you should use a QNX
#      boot floppy and mount the hard drive manually.
#   3. Login as root.
#   4. Verify the Master drive has the kernel built to force LBA option
#      during boot up.  Check /boot/build/hard.?? has the line
#      "Fsys.eide fsys -h 64,63", (i.e, sectors,heads for LBA mode.)
#   5. Run this script.
