[comp.sys.mac.hardware] Question about Seagate ST225N drive

I have a question regarding a Seagate ST225N 20Mb 5.25" hard disk.

I recently acquired a HyperDrive FX/20 (yeah, an oldie :-) ) and was
wondering if anybody knew about the ST225N.  I have a couple of
questions:

1.) About the three SIP sockets on the PC-side of the drive.  Are these
    the SCSI terminators, and if so, can they be used to terminate the
    drive, rather than the external (bulky) terminators, as usually needed?
    I don't plan to use the unit anywhere where I'll need to remove the
    termination.
    Also, if these are the SCSI terminations, what value component and is
    there a proper orientation for it?

2.) What makes a HD unit you purchase from a third party different from
    another third party when the drive unit inside the box is the same?

3.) Suppose I purchase an ST157N-1 for use with my Mac. What do I need to do
    to ensure that this unit works with my Mac?  What about formatting?


Thanks in advance,
Taylor
