The most sensitive components in a Macintosh system are:
1) the floppy disk drive
2) the hard drive
Here are the vibration limits for floppy drives:
- Operating Limit: 5 Hz - 500 Hz at Max. .5 G
- Non-Operating Limit: 5 Hz - 500 Hz at Max. 2 G
For vibration limits of hard drives, perform a search on the hard drive itself. The specifications for the drive will state its vibration or shock limit.
