Computers or laptops come with a single drive usually C drive and that is your hard disk with single partition (in most cases). Second drive or partition is kept reserved for system or contains Windows restore files. Its recommended to create at-least two or more partitions of hard disk so that you may distribute your data in those separate drives according to the data category. For example, keep Windows operating system in C partition, keep work files in partition D and keep entertainment data, music, videos in E partition. If you do not have multiple partitions, its a good idea to ask for help from your geek friend or local computer shop to create partitions of your hard disk. You do not have to re-install operating system to create more partitions in hard disk. Partition software can do it safely. So after having multiple partitions or disks in your computer you can hide any drive if you like. You can do this for security purpose or just for fun. Here is how to do it.
