- I've been working with VMS for a while (8 years) and it's file system is
- extremely reliable apart from the usual RMS bugs in major releases of VMS
- (4.0 !!). The only cases of corruption I encountered were related to
- media problems ... and no magic can give you back your data in these
- cases ! In the Unix world most of the time a damaged file structure is a
- major headache and typically your system will crash. You need to
- "fsck" your system (and answer frightening questions) at boot time.
-
- I agree with Don, a crash is never a good thing in the VMS world and you
- should avoid these as much as possible.
