- Cute. Sometimes you just don't get that luxury. And it STILL is no
- substitute for file recovery. Accidents happen. File recovery
- is rather like seat belts and air bags. AFS doesn't give you
- access to those.

- I get a fairly good rate of recovery from a disk which has not been
- writen to after an accident under FFS. Not so under AFS. A simple
- deletion of files with NO writes to that drive is beyond recovery
- under AFS. It's that simple. The partition I refere to has not been
- accessed since the deletion accept by DS4 for salvage only. No writes.
- It is otherwise unmounted.
