dd_rhelp is a bash script that handles a very useful program written in C by
|
||
|
|
Kurt Garloff which is called dd_rescue, which roughly acts as the dd(1) command
|
||
|
|
with the characteristic to NOT stop when it falls on read/write errors. But
|
||
|
|
using it is quite time consuming. This is where dd_rhelp come to help.
|
||
|
|
|
||
|
|
In short, it'll use dd_rescue on your entire disc, but will try to gather the
|
||
|
|
maximum valid data before trying for ages on bad sectors. So if you leave
|
||
|
|
dd_rhelp work for infinite time, it'll have the same effect as a simple
|
||
|
|
dd_rescue. But because you might not have this infinite time (this could indeed
|
||
|
|
take really long in some cases...), dd_rhelp will jump over bad sectors and
|
||
|
|
rescue valid data. In the long run, it'll parse all your device with dd_rescue.
|
||
|
|
You can Ctrl-C it whenever you want, and rerun-it at will, it'll resume its job
|
||
|
|
as it depends on the log files dd_rescue creates.
