Copies data from file or raw harddisk ignoring Bad Blocks. If target file doesn't exists, ZEROs are written instead of unreadable blocks. If target file exists, its blocks, coresponding to Bad Blocks in source are not touched. Thus, if you have some copies of the same file with Bad Blocks in different places, it is possible to completly restore the original file. To do this you should run bbcopy.exe with same target, but different sources. You can use other harddisk of same of greater size as target.

Works under all Windows versions - Windows (95/98/Me/NT/2000/XP/etc.).

Usage:
  bbcopy.exe [-<switches>] <source file> <target file>
    or
  bbcopy.exe [-<dd-style options>]
Switches:
  -b[k] <blocksize>   sets physical block (sector) size for media. 2048 (2k) is default.
  -B[k] <blocksize>   sets I/O block size. 64k is default.
  -o[b|k|m|g] <offset>  offset in bytes (or optionally in blocks, KBytes, MBytes or GBytes)
                      to start recovery from
  -c[b|k|m|g] <count>   number of bytes (or optionally in blocks, KBytes, MBytes or GBytes)
                      to recover
  -r <retry>          number of retry attempts. 3 is default
  -e <max errors>     abort copying after specified number of sequential errors
  -f                  fall-back to physical sector-by-sector mode, when I/O block
                        cannot be read in single request (contains some bad sectors)
  -l <logfile>        log unreliable and bad blocks to <logfile>
  -s                  fill unreadable parts with '** BAD BLOCK ***'
  -S <string>         fill unreadable parts with <string>
                      Do not use fill patterns if you restore from multiple copies
  -n                  use NO CACHE option for file/device I/O
                        This option is automatically enabled for block devices
  -d[i|o] <num>       specify input (i) or output (o) block device <num>
                        this is short form for \\.\\PhysicalDrive<num>
  -?                  display this help
DD-style options:
  if=<source file>    or    ifd=<num>
  of=<target file>    or    ofd=<num>
  bs=<bytes>
  iobs=<bytes>
  ioseek=<blocks>
  count=<blocks>
Note:
  1 KByte = 1024 bytes
  1 MByte = 1024 KBytes = 1024*1024 bytes
  if byte offset or byte count is specified, it will be rounded to blocksize
Examples:
  bbcopy.exe -o 5000000 X:\Video.dat E:\Temp\Restored_Film.dat
    will copy data starting from byte offset 5000000 to end of file
  bbcopy.exe -om 1300 -cm 1000 X:\Video.dat E:\Temp\Restored_Film.dat
    will copy not more than 1000Mb of data starting from byte offset 1300Mb
  bbcopy.exe -f -r 1 -b 512 -Bk 64 -l hdd.log \\.\\PhysicalDrive2 \\.\\PhysicalDrive3
    or
  bbcopy.exe -f -r 1 bs=512 iobs=65536 log=hdd.log ifd=2 ofd=3
    will copy from harddisk2 to harddisk3 with optimal transfer block 64k
    if 64k cannot be read, fall back to 512 bytes blocks for damaged area

The latest version with sources - bb_copy_v2c.rar/tgz (39.3 Kb/42.9 Kb)

Still one new feature - bad and unreliable block logging. You can leave utility alone and later view information about damaged parts of file.
