d'Oh!

If FCP were testing the bSupports2TBFiles bit, which VOP/VFS interface
would the Carbon File Manager be using to ask us the answer? I'd like
to put the code in now so that it will all just work when FCP/CFM are
fixed.
Thanks Quinn,

Hmmm, I think that there are least two issues here. For a start, FCP
(or whatever underlies it) should determine whether a volume supports
large files by testing the bSupports2TBFiles bit in the
vMExtendedAttributes field of the GetVolParmsInfoBuffer returned by
the Carbon File Manager routine PBHGetVolParmsSync. However, it
doesn't look like it's doing this (because of the next point). I'd
consider that a bug.
Second, it seems that the Carbon File Manager sets this flag based on
a simple volume identifier check. If the volume is original HFS, it
clears the flag, otherwise it sets it. This is a bug IMHO. The
Carbon File Manager should not contain hard-wired special cases for
particular file systems.
You know the drill...
