   Hello Patrik!

27 Aug 17 12:33, you wrote to me:

Yep, it looked that way, but...

.... I always did a full format and not a quick format. Guess, that was the
mistake why it didn't work. :-)

 PA>>> OS3.9 is nice and has a more user friendly HDToolBox, however it

Yes, exactly! The new icons look awful - or something is wrong with my palette.
 However, OS3.9 is a leap forward in regards of large disks, so I guess I'll
stick with it... :-)

Anyway, thanks for your support! :)
Ingo
