Re: [Bug-ddrescue] another idea for ddrescue (interleaved reads for "-d" )

I added a status line to the logfile because it is needed to make the 
operation of the planned --fill option interruptible, but I found it 
useful for other things.

You may have noticed that I have released a pre-release, not a release 
candidate. This is because I want to implement the --fill option and 
support for sparse output files in 1.6, and I want it to be very well 
tested. I hope the people in this list can help me with the testing. Thanks.

Really sounds complex. :) I am not sure if it would be worth to 
introduce this complexity into ddrescue even if it proves to work.

Perhaps the experiments could be easily done by means of a hand crafted 
logfile with the sectors to be read marked as bad and the rest marked as 
good.
