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 v1.0.6 - Copyright (C) 1992,2003 Bisqwit (http://iki.fi/bisqwit/)
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.

This is a program to copy a file or data stream to another file or data stream.

faildd has been written by Joel Yliluoma, a.k.a. Bisqwit,
and is distributed under the terms of the General Public License (GPL).

A C++ compiler is required. The program also requires LARGEFILE support which is only available in recent versions of POSIX compliant operating systems such as Linux.
