   Dunno.  I was just reporting the reason supplied by the person 
responsible.  I suspect the errors are small but cumulative, which would 
allow for corrections as long as the next shutdown was normal.  Thus, it 
may take a lot of fast boot/power outage executions in a row for the 
error correction to not catch up.

   As for mission critical Windows boxen, I'm mostly familiar with NTFS 
used in mission critical control systems, where it does not get rebooted 
very often, now that the 45 day issue is resolved.  I'm not sure it's 
safe to say there are millions of mission critical machines running 
Windows - there certainly are millions of Windows machines, but most of 
them are not mission critical.

   My experience is that NTFS is more stable than it used to be.  I can 
remember early versions of NT 4.0 eating itself - literally overwriting 
chunks of the winnt directory/folder.  I haven't had that happen in a 
long while.
