Failsafe dd

Imitate the behavior of the unix tool dd, but in a way that is suitable for copying the contents of a broken hard disk to another.
That is, ignore read errors, don't desync in stream positions and aim to minimal data loss.

Failsafe dd v1.0.1 - Copyright (C) 1992,2002 Bisqwit (http://bisqwit.iki.fi/)
faildd comes under GPL and is purposely made to feel like the standard dd.
Usage:
   faildd [OPTION] ...
Copy a file, not choking when disk errors happen.

  bs=BYTES        force ibs=BYTES and obs=BYTES
  count=BLOCKS    copy only BLOCKS input blocks
  ibs=BYTES       read BYTES bytes at a time
  if=FILE         read from FILE instead of stdin
  obs=BYTES       write BYTES bytes at a time
  of=FILE         write to FILE instead of stdout
  seek=BLOCKS     skip BLOCKS obs-sized blocks at start of output
  skip=BLOCKS     skip BLOCKS ibs-sized blocks at start of input
      --help      display this help and exit
      --version   output version information and exit

BLOCKS and BYTES may be followed by the following multiplicative suffixes:
xM M, c 1, w 2, b 512, kD 1000, k 1024, MD 1,000,000, M 1,048,576,
GD 1,000,000,000, G 1,073,741,824, and so on for T, P, E, Z, Y.

A C++ compiler is required. The program also uses the _llseek() syscall available only in Linux. You probably have to customize the program if you want to use it in something else than Linux.
