I've got two Macintosh IIcx systems with 40MB hard drives that on occasion 
do not spin up on a cold start. Continually turning off and then turning 
on the power has no effect. Both systems have 40MB drives, one is a Sony 
drive the other I'm not sure - I haven't looked. This problem occurs every 
couple of weeks on these two systems, I've got ten other IIcx systems that 
do not have this problem. The odd thing is that I can always start the 
disk spinning by rapping on the side of the Macintosh or by opening the 
Mac and tapping the drive. Is this a known problem with some of the Apple 
provided hard drives? Our dealer didn't know of any problems with IIcx 
40MB drives. Both systems are still under warrenty so I guess I'll wait 
until it happens again and call in the dealer to replace the drives. Any 
thoughts?

Thanks,
Mike Cherry
