Artpics, did you get all fixed up?
if you still need to restore you all time records, and can;'t get it from the ini file, you can also re-import the logs if they are in good shape, from the Action>Convert Log files to Graph... I have done this many times in the past when WD was less stable than today... haven't had to for many months now, but it worked great (see my site) That command will step through every month's logs and look for extremes and reset the all time records.
Hope this helps.
Sorry I was travelling stateside last week and am just getting caught up on the forum today.
All the best
Jim
