     1.4 +Like dd, dd_rescue does copy data from one file or block device
     1.5 +to another.
     1.6 +You can specify file positions (called seek and Skip in dd).
     1.7 +There are several differences:
     1.8 +
     1.9 +* dd_rescue does not provide character conversions.
    1.10 +* The command syntax is different. Call dd_rescue -h.
    1.11 +* dd_rescue does not abort on errors on the input file,
    1.12 +  unless you specify a maximum error number. Then dd_rescue
    1.13 +  will abort when this number is reached.
    1.14 +* dd_rescue does not truncate the output file, unless asked to.
    1.15 +* You can tell dd_rescue to start from the end of a file and
    1.16 +  move backwards.
    1.17 +* It uses two block sizes, a large (soft) block size and a small
    1.18 +  (hard) block size. In case of errors, the size falls back to
    1.19 +  the small one and is promoted again after a while without errors.
