Projects / dd_rhelp


dd_rhelp allows users to retrieve, quickly and easily, recoverable data from any device with bad sectors. It will copy it using dd_rescue in all the appropriate ways (reverse copy, setting start and stop offset accordingly to previously rescued data) to recover the maximum data possible before spending time on bad sectors. It is straightforward to use, supports ctrl-c at anytime, can resume a job (or standalone dd_rescue job) by parsing the dd_rescue logs, and displays a nice ASCII bar showing rescue progress.

    Release Notes: The main algo is somewhat cleverer than before by going first forward then backwards, and by choosing a bias to favor forward dd_rescuing, which is often much quicker. Also, this algorithm should be quicker thanks to multiple cached values. This release includes improved Mac OS X support (use of BSD tools) and was the object of new tests. Small improvements (as a human display of byte sizes) and bugfixes were added. SUSE patches have been merged.

      Release Notes: Some annoying bugs were corrected. Installation is easier. Log file creation is checked for a sane environnement. More and simpler information is displayed. The behavior has been tweaked to avoid creation of too many data chunks, which greatly slowed the execution of dd_rhelp and the recovery process.

        Release Notes: A problemwhere the program wouldn't start a rescue at the very beginning of the process was fixed. Some small changes were made towards Mac OS X compatibility.

        •  04 Jul 2004 13:24

          Release Notes: A bug that could stop disk recovery in some circumstances was corrected. Some minor code rewrites were done.

          •  13 Jan 2004 01:21

            Release Notes: Minor changes in reports to output better information. Silly bugs (mainly installation ones) have been corrected, which has resulted in increased portability. The documentation has been updated slightly with a new FAQ and some updates and typo fixes.
