To do this, you will need basic understand of how to enter Terminal commands and use vi.
1) Make sure the disk you want to prevent mounting at boot is mounted.
2) Launch Terminal.
3) Run the following command to print out information about the disk:
diskutil info /Volumes/shouldn't be mounted>
4) Locate the line that starts with: Volume UUID:. Select the UUID (Universal Unique Identifier) that follows on the rest of the line. It will be something that looks like FF9DBDC4-F77F-3F72-A6C2-26676F39B7CE. Your value will be different

6) Navigate to /etc by typing the following and pressing enter:
cd /etc
7) Edit (or create) an fstab file by typing the following and pressing enter:
sudo vifs
8) Enter the following line, substituting the UUID you copied in step 5). (Note: vifs uses the value of the EDITOR environment variable to pick the text editor to use. This article assumes you are using the default value of vim.) In vim, the editor starts in command mode. To add a new line, use the arrow keys to move to the end of the document and press the o key to append a new line and enter edit mode. Then type the following:
UUID=FF9DBDC4-F77F-3F72-A6C2-26676F39B7CE none hfs rw,noauto
and press the return key.
9) Type escape to return to command mode and then type ZZ (shift key down) to save and exit vifs (or some other method to save and exit if you are using something other than vim).
10) Type the following and press enter to reset the auto mounter:
sudo automount -vc
11) Quit Terminal
Now, the next time you restart, or unplug the drive in the case of an external drive, that volume will not be mounted. All you have to do is launch Disk Utility, select the grey, disabled volume, and click the Mount button.
You should be able to use a different text editor than vifs if you want. It needs to be able to edit and save files owned by root.
Note: If all of your disks are encrypted, there is an easier method. For any disk that you don't want to automatically mount, simply don't save the password to the keychain.

Encrypting a USB drive so only authorized users have access is always a good idea when dealing with sensitive or private information. But what happens when you want to access that same data on a Mac and you don't have the ability to use the same software to decrypt and unlock the drive? BitLocker for Windows poses exactly that kind of problem because it only works on Windows computers. So, if you're using a USB drive encrypted by BitLocker on a Mac, there's really no direct way to access the content in encrypted drive on Mac. Fortunately, there's a workaround for it, which is what this article outlines.
Although BitLocker is not natively supported on Mac machines, there are several third-party tools you can use to gain access to a USB drive that has been encrypted with it. One such utility is UUByte BitLocker Geeker. The software is compatible with Mac OS X 10.10 and higher versions, and can open a wide range of storage devices like USB drives, external hard drives, SD cards and more. You can also use it to read or write files to the drive, but that involves formatting the drive with a Windows-friendly file system like NTFS or FAT32.
