Hiding a Partition from my computer or explorer can be extremely useful when you have some sensitive information on the local disk and you want others to stay away from it. After you hide a partition, the partition will be invisible to all users until you manually unhide it.
Windows OS Disk management system allows hiding drive except the System drive where the OS is installed and volume is reserved for the OS. Hiding a drive does not means deleting the volume or erasing any data but it only prevents that partition from displaying. For doing this the user must have administrative access to the system.
In future if you want to use it again, simply unhide it and it will then show up again in My Computer and Explorer.
