Throwing an error saying, for example 

"You didn't specify a logfile.  You probably wanted to.  Use the -f flag
to proceed without a log file."

...is radical?  I think it's far less problematic than the number of people
who regret not using a logfile two days later.

Somebody back me up here :)

Okay, thanks.  Yes, I was checking the size of ddrescue in ram to see the
size of the buffer.  Crashed my computer with larger values a couple
times.  The units confused me.

I was thinking just check the size of the output file and continue at its
end?
