What filesystem does each represent?
And why is there not an lls to list whats at the point of a successful lcd, like an ls does for a cd? One or the other didn't work, I've forgotten which and not being able see where I was, and verify which filesystem was what got so confusing I gave up and used a variation of the first blocks command line to extract the whole 7+gigs of picnc's /, then I walked thru it with mc and copied what I needed. That took half an hour, and just worked whereas I'd been screwing with amrecover for 2 days. And FWIW, the commandline in block 1 of the file is bogus, eats cpu like they were M&Ms, and 20 minutes of bouncing from core to core didn't output a single byte, so I turned the last tar command in that pipelined chain around to 'tar x -', and had the whole thing in a navigatible filesystem in the scratch dir of the same drive.
