ddrescue

copy data from one file or block device to another

dd_rescue is a tool to help you to save data from crashed partition. Like dd, dd_rescue does copy data from one file or block device to another. But dd_rescue does not abort on errors on the input file (unless you specify a maximum error number). It uses two block sizes, a large (soft) block size and a small (hard) block size. In case of errors, the size falls back to the small one and is promoted again after a while without errors. If the copying process is interrupted by the user it is possible to continue at any position later. It also does not truncate the output file (unless asked to). It allows you to start from the end of a file and move backwards as well. dd_rescue does not provide character conversions. Please note that this is the dd_rescue version of Kurt Garloff providing the /bin/dd_rescue executable. If you are searching for the GNU ddrescue version please check out the gddrescue package instead.
