If you want to hide a partition on your machine, you could use following method to achieve your purpose:

1.Type “diskpart” in run command box without quotes. (A command window will get opened)

2.Then type “list volume“. (Your hard disk partitioned volumes will be listed)

3.Now type “select volume <volume number>” – (Volume number is the numeric variable which is shown in the volume listing)

4.Type “remove letter <volume letter> – (Volume letter is the alphabetic character of the drive such as C,D,E,F…Z)

This one is the easiest method. Will update thread with other methods shortly.
