Hi, Gralfus!
The only way I could make it hang here was to manually go through Explorer (without having the TC volume - "My Volume" - mounted) and trying to either defrag or erase freespace on "My Volume" itself.
It won't do it - or if it will, I 've never left it trying long enough to find out.
What I finally wound up doing was using FolderHide on "My Volume", to take it out of the equation entirely unless I actually wanted to mount the volume in TC (at which time, I un-hide it, of course). Pete
