       ddrescue - data recovery tool


       ddrescue [options] infile outfile [logfile]


       GNU  ddrescue - Data recovery tool.  Copies data from one file or block device to another,
       trying hard to rescue data in case of read errors.

       You should use a logfile unless you know what you are doing.

              overwrite output device or partition

       -F, --fill=<types>
              fill given type blocks with infile data (?*/-+)

       -g, --generate-logfile

       -p, --preallocate
              preallocate space on disc for output file

       -q, --quiet
              suppress all messages

       -r, --max-retries=<n>
              exit after given retries (-1=infinity) [0]

       -R, --reverse
              reverse direction of copy operations

       -s, --max-size=<bytes>
              maximum size of input data to be copied

       -S, --sparse
              use sparse writes for output file

       -t, --truncate
              truncate output file to zero size

       -T, --try-again
              mark non-split, non-trimmed blocks as non-tried

       -v, --verbose
              verbose operation

       Numbers may be followed by a multiplier: b = blocks, k = kB = 10^3 = 1000, Ki = KiB = 2^10
       = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
