Exactly what important invisible files get missed? (n/m; see below)

Copy how? Surely you aren't recommending drag-and-drop copying to duplicate an OS X volume. Simply copying files to a backup device won't get the invisible files that are at root level of the disk's directory structure. (It will get invisibles that are inside folders.)

Worked for me, Lombard (OS 9 and Jaguar) to our new PB (Panther).

The system files you simply don't want. The only things of interest to copy out are visible so they copy perfectly well with a simple drag'n'drop...

Numerous invisibles that reside at root level of the disk are ...
-- System files, like boot blocks and other disk data, like drivers, etc.;

Lombard vs eMac. You can't use the boot blocks. And the eMac has its own drivers.


-- some caches and other files associated with various software;

Caches, by definition, should never be copied. Other files?

-- Desktop Folders for the disk which carry the Finder's icon and
file placement information (not the disk directory);

Are best recreated fresh.

-- disk directory information that says where every bit and byte is
physically on
     the disk;

You're moving the data to a new drive, so this information is moot.

-- some key code and serial number and validation files for some programs.

Most apps will reask for their s/n even if you copy their prefs files over. The ones that don't probably need to be installed on the new machine properly anyway.


I've been tod that there are approximately 120,000 files installed
with OS X (complete install I assume). I've never tried to count
them, so I'm going to take this at face value. That's an enormous
amount of files to be dragging-and dropping.

The new eMac comes with its own operating system. We're talking about copying USER data here, and maybe a few apps.
