[X-Unix] Renaming "NO NAME" Flash Disks

[Jerry Krinock]

Thank you all for sharing your knowledge on "Macintosh compatibility" of
flash disks.  It has been very useful.

I have one more question.  How can I rename one of these foreign flash disks
in OS X?

In OS X, it shows up in the Finder as "NO NAME".  The name is not enabled
for editing.  I cannot do it in Terminal either.  Here's what happens:

ENG1-0020:/Volumes jk$ mv "NO NAME" MyDisk
mv: rename NO NAME to MyDisk: Operation not permitted

However, if I plug it into an old Mac booted into OS9, the name is enabled
for editing!!  When I change "NO NAME" to "MyDisk", and look in the file
browser on the MP3 player, I see it has created a file at the root level
named MyDisk.  The amazing thing is that this file is not visible in the
Finder, and also does not show in Terminal when I type "ls -al".  I wonder
what kind of magic file is this?  How does a disk know it's own name?
