HISTORY 

2021-03-17: Version 1.4
* I (Holger Hippenstiel) reported slow speed on big files and after writing
  Bebbo about it, i have added 64k buffers via setvbuf to read/write operations making
  them upto 17 times faster.
  I have made a similar tool which handles a whole drive ->
  http://aminet.net/package/disk/misc/DriveMirror

2021-03-14: Version 1.3
* use NSCMD_TD_READ64 and NSCMD_TD_WRITE64 to support devices > 4GB
* add a patch command to update the RDB with custom values

2020-11-03: Version 1.2
* write cmd misspelled (due to renaming...)

2020-11-03: Version 1.1
* print kiB (=1024 bytes) instead of bytes
* print partition names
* show progress bar

2020-11-02: Version 1.0 initial release.

================================================================================
SYNOPSIS 

partcopy list  <device> <unit>						display the partitions
partcopy read  <device> <unit> <n> <file>			copy the partition <n> to the <file>
partcopy write <device> <unit> <n> <file>			copy the <file> to the partition <n>
partcopy patch <device> <unit> <heads> <sectors>	modify disk geometry to the given heads and sectors

================================================================================
EXAMPLES

List the partitions:

> partcopy list scsi.device 1
partcopy 1.1
using scsi.device 1
block size = 512 b
found RDB at 0 using 512 kiB per cylinder
partition #0: block 1:     UDH0 [     2 -  1366] = 698880 kiB
partition #1: block 2:     UDH1 [  1367 -  2731] = 698880 kiB
partition #2: block 3:     UDH2 [  2732 -  4095] = 698368 kiB

Backup a partition:
> partcopy read uaehf.device 1 0 part0
partcopy 1.1
using uaehf.device 1
block size = 512 b
found RDB at 0 using 512 kiB per cylinder
partition #0: block 1:     UDH0 [     2 -  1366] = 698880 kiB
partition #1: block 2:     UDH1 [  1367 -  2731] = 698880 kiB
partition #2: block 3:     UDH2 [  2732 -  4095] = 698368 kiB
copying partition #0 UDH0 to file p0.raw
==================================================100
done

Restore a partition:
> partcopy write uaehf.device 1 0 part0
partcopy 1.1
using uaehf.device 1
block size = 512 b
found RDB at 0 using 512 kiB per cylinder
partition #0: block 1:     UDH0 [     2 -  1366] = 698880 kiB
partition #1: block 2:     UDH1 [  1367 -  2731] = 698880 kiB
partition #2: block 3:     UDH2 [  2732 -  4095] = 698368 kiB
copying file p0.raw to partition #0 UDH0
==================================================100
done
