I can't duplicate the bug cited above (speed disk resulting in two files
using same physical part of disk), but I have seen the following happen,
three times on two different macs:  QM Administrator (quickmail, CESoftware)
crashed.  I run Disk First Aid (Apple's program to check fsys structures
on disk, which i try to run after every crash...surprising how often
programs crash with files open and...trash some directory structure or
something), it reports something needs fixing (that's all it ever says,
never explains what), i say fix it.  I run Norton's Disk Doctor, it finds
a couple serious things wrong (volume bit map, and something blocks...i
wrote it down, but not with me now...), i say fix it.  I re-run disk first
aid, it reports problem (again!), i say fix it...


u get the idea?  Each program "fixes" something, which causes the other
program to see something wrong and "fix" it...they fight each other!  So, who's
right?  I called Norton and they seemed unknowledgeable and uninterested in help
ing.
Since Apple wrote the file system, i would tend to trust their file system
checker (disk first aid) in such a dispute...but bottom line:  i backed
up entire disk (daisy chained another hard disk), reformatted, and restored,
to be safe.  Then, of course, both disk first aid and norton agree that
disk is good.

Anyone else seen this?  Any ideas what it might be?
