Appendix
If your computer's processor supports Hyper-Threading, this option appears
in the Options List.
• Bypass (default) — Your computer does not test or change the current
acoustics mode setting.
• Quiet — The hard drive operates at its most quiet setting.
• Suggested — The hard drive operates at the level suggested by the drive
manufacturer.
• Performance — The hard drive operates at its maximum speed.
NOTE:
Switching to performance mode will cause the drive heads to move
faster, causing the hard drive to be noisier. However, some drives may not see
an increase in data transfer rates.
NOTE:
Changing the acoustics setting does not alter your hard drive image.
