Subject: Re: Identifying a volume as being an iPod

Well, I've found better stuff to work with, more practical anyway.

in:
/Volumes/ipod_name_here/iPod_Control/Device/
there is a nifty little file called SysInfo

I wouldn't dare modify it, but it is worth reading. In fact, I would  
almost recommend creating read-only method to wrap whatever methods  
you want to use to open and read the thing. Just to avoid any chance  
of stepping on this file.
I have replaced my serial number with a five asterisks. You only need  
the first 3 characters of a serial number on the ipod to identify it.
The most important line is line 3, the model number.
You could, if you were diligent, check to see that the first 3 chars  
of the serial number match the model number for the type of iPod.
If you were overly diligent, you could try to check the serial number  
against Apple's web site somewhere.

Anyway, let's just say we've got more than enough to say the device  
is probably an iPod and is likely the one you want to transfer music  
from to an authorized iTunes. The odds of having multiple iPods  
connected to one computer are pretty low. It happens, but not much.  
That's no big deal, we just have to add a check to ask the user  
running the program which iPod they want to transfer from, since the  
name of the iPod is the same name in the terminal.

Now all we need to do is script the Finder to move the files into  
iTunes!
After I finish learning just enough AppleScript, I will convert it to  
RubyOSA...
