-There are some predefined settings:
-  * stage1: Preset to rescue most of the data fast,  using  no  retries  and avoiding bad areas.
-  * stage2: Preset to rescue more data, using no retries but  searching  for exact ends of bad areas.
-  * stage3: Preset to rescue everything that can be  rescued  using  maximum retries, head realignment tricks and low level access.
-In current working directory, safecopy will create files with badblocks map: stage#.badblocks, which are used in next stages.
-Typical usage is:
-<code bash>
-safecopy --stage1 /dev/source output.img
-safecopy --stage2 /dev/source output.img
-safecopy --stage3 /dev/source output.img

-===== on usb drives =====
