[Bug-ddrescue] Algorithm Question

[nik . thirtynine]

Hi,

I am fairly new to ddrescue so please forgive me if the answer to
these questions are obvious (I searched for an answer of course :) ).

The ddrescue.info reveals how the algorithm works but it is not very
clear. So my questions are:

- How does ddrescue work on defective sectors? When does it decide to
skip sectors and much more important: how does it determine the size
of sectors to skip or jump ahead?

- Also I have read something about backward reading capabilities but
haven't seen ddrescue actually reading backwards. Does the current
ddrescue read backwards? If so - when?


Thanks for your help in advance
