[Bug-ddrescue] Is it possible to gather sth from the logfile of an ongoing rescue

[rdkrsr]

Hi!

I have a corrupt 2 TB hard disk with mainly video files (NTFS, one
volume, recorded by an DVB-S device). I have not very much hope to
rescue something because at the beginning of the weird behaviour of
the drive I might have worsened the state of it (use of Partition
Magic etc.). There is no recognition of any file system and there are
i/o errors. At the beginning the movies were "pausing" more and more
during playback. Then it took unbearably long to copy something off of
the drive. So I guess the drive is lost.

Question: Yesterday I startet a ddrescue and it shows at the moment an
average rate of 500 kB/s, which would mean more than 30 days for the
process. So I wonder if there is a possibility to say something about
the usefullness of the copied data by looking at the logfile.

The file starts like following and goes on like that (+,-,*,+,-,*, ...)

Cheers,
rdkrsr
