Ah, the simple joys of being held up as an example of what not to do ;-).

Yes, having learnt the hard way, I'd suggest that you not write to a 
network file system and particularly not an CIFS/SMB filesystem.  I have 
no experience with using NFS for log files, but based on past experience 
I wouldn't go there.

Practically, what this means, is that if you are using ddrescue from a 
live CD (as I was) you need a known good drive to store the log file to 
in addition to the drive you are copying the restored data to.  A USB 
stick may be suitable, though I haven't tried.
