Sure, but it makes defragmentation much more complex,
and requires maintaining chain pointers to other bits
of the file.  I agree that a chained system is more
useful for large systems with frequently changing files
(frequently = many times a day), but the player just
doesn't need that kind of system.

Also makes it a pain in the ass to get a list of all
the files in the system if you don't have a list of
files somewhere (who wants to search the whole drive
surface looking for start chains), and if you have
a file list somewhere, why not just store all the
info there and leave the files in one piece?
