 As I already told you: you had not supplied enough airflow to the drive.
Cooling air with at least 0.6m/s is a *must* for the bigger drives. The Grand
Prix was - when you purchased it - already almost end of life (means:
not up to date at all). Micropolis was, no wonder the drive is stable.

 The IBM is making more noise? That a big-tower is shaking because he 
installed a hard drive in it, sounds more olike the drive was installed
at the wrong place. The same can happen if you install a CD-ROM - it will 
even shake, rattle and roll :-) The Atlas turns with 7500RPM, the IBM at 5400.

 No, FireBall is.
