It started off this session with 629 different areas with errors which totaled
1500 kb of missing data. So far, it has been able to recover some of that
missing data. In doing so, it broke up the error spots.
So the areas before and after the newly recovered data now count as individual
errors - the number of individual error spots goes up while the total amount of
missing data goes down.

Thigns are going well, but I was wondering, here is what I ran for the second
run to get data of the parts of the disk with errors:
a...@al-ubuntu:~$ sudo ddrescue -r1 -v /dev/sdb /storage/test.bin testlog
About to copy 160041 MBytes from /dev/sdb to /storage/test.bin
Starting positions: infile = 0 B, outfile = 0 B
Copy block size: 128 hard blocks
Hard block size: 512 bytes
Max_retries: 1 Split: yes Truncate: no
Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 160040 MB, errsize: 1507 kB, errors: 629
Current status
rescued: 160041 MB, errsize: 757 kB, current rate: 0 B/s
ipos: 4363 MB, errors: 1480, average rate: 17 B/s
opos: 4363 MB
Now if I read this correctly, it read from the log file that after the first
pass there was error size : 1507Kb?
And if I keep reading it says after the pass with -r1 option it now only has
(it completed) error size : 757Kb?
This is a reduciton in the total error size - I assume this is good?
But how can the error size go down, yet errors goes up (from 629 to 1480)?
Thanks in advance - trying to understand the program better!!
Cheers
