How to avoid mounting all drivers?

[Xi Shen]

Hi,

On my system, I have two drivers, C: and D:. I do not want D: to be mounted at /cygdrive/d. I tried to modify /etc/fstab, but no matter I remove the default line, or explicitly set up for C: only, both drives will be mounted. Is there any way to stop auto mounting?

Thanks,

David
