Well, I'm not a noted expert on ddrescue, but my limited experience tells me that when it hits bad spots (or a big cluster of them) it can go very slowly as it tries multiple times to read each sector (or track, I'm not sure which, in this case). It keeps a list of bad spots and goes back at the end to try again to read something from them. Of course, if you've had, eg. a head crash, there's probably nothing there to read.

Hello
I did try the "dd conv=noerror …" The ddrescue - doesnt stop - it just doesnt "continue" past a certain point. Somewhere around the 117G mark - it just doesnt go past that . (same with dd, gets to 117G and just doesnt continue. I have let the dd run all night - did not go past the 117G.
Thanks for any suggestions.
