Last night, I repeated this rumor to Mark James of Jasmine Computer.  He
gave the following explanation of how such a false rumor might have
started.  Seagate does sell its disks with a variety of no-cost options.
So, it's true that the disks received by different purchasers are
different.  The difference is *not* in quality, however, and the differences
are at the customer's request.

For the ST225N, options include: noise
level (there's a "low-noise" 39dB option); LED; terminating resistors; and
mounting arrangements.  Mark cited two differences between the drives used
by Apple and those used by Jasmine: Jasmine uses Seagate's LED (what does
Apple do?) and Jasmine uses Seagate's terminating resistors (Apple makes
you buy a separate cable terminator for extra $$).

Claimer: I have a business relationship with Jasmine.  But you can call
and ask them for yourself.
