[Bug-ddrescue] no logfile written / logfile only (without image)

[bill evergreen]

Hello

ddrescue seems to be the tool i have been waiting for  and do havve 2
questions/concerns:

1.
Why the following command does nothing write to the no logfile :-(


deft8 ~ % sudo ddrescue  -d -v -n /dev/sdb
/media/root/1234567890123456/QNAP/QNAP.dd logimage.log

GNU ddrescue 1.16
About to copy 1000 GBytes from /dev/sdb to

    Starting positions: infile = 0 B,  outfile = 0 B

   opos:     1035 kB,     time since last successful read:       0 s


2.
Is itpossible to have ddrescue made a logfile (but without saving the image
itself)?
How?


Thank you very much for any help!
