Re: [Bug-ddrescue] Enhancement Request: Display Error Information in Passes 1-3, check -A functionality

Ah, I was using 1.21 since that's what came with the "System Rescue CD" 
that I used as my Unix environment to run ddrescue. From the sample 
output you showed it looks like it addresses my suggestion to a large 
extent--thanks!

Ah, thanks, I missed that. In fact, based on the description of -M

"-M / --retrim / Mark all failed blocks inside the rescue domain as 
non-trimmed before beginning the rescue. The effect is similar to 
'--retry-passes=1', but the bad sectors are tried in a different order, 
making perhaps possible to rescue some of them."

it seems that -M is what I really wanted instead of -A (I was misled by 
a blog post somewhere that suggested -A). From my reading of the above, 
though, it seems like -M alone is what I would need (i.e., without -A), 
no? What's the difference between -M alone and -M -A together?

Thanks again for taking the time to respond, Antonio.
