Hiding the Bootcamp partition
If you have a bootcamp partition, but don’t need frequent access to the partition, you may not want it showing up all time, cluttering up the Desktop/sidebar, and potentially letting other users accidentally mess up your Windows install. While Parallels is running it hides the Bootcamp partition (at least if you are running the Parallels from Bootcamp option), but the rest of the time….
You can prevent the partition from being mounted easily enough by editing your fstab file. Those of you used to a more traditional Unix/Linux may be shocked to not find a file at /etc/fstab in the first place. Go ahead and make one, ignoring the /etc/fstab.hd file. In your new fstab you can just put the instructions for the noauto windows partition – that will leave the rest handled as usual by OS X. The following are the contents of mine, for handling my FAT partition.
