Many of you know how to hide your important files and folders and burn them to disc to keep them from being accessed from other users, but if you your drive has so many files that it would take too long to copy all to disc, then why not hide the entire drive.

Two methods, 1st one involves editing the registry, so again, back it up;

1st method found here;

2nd method: Control Panel/System and Security/Administrative Tools, click on Create and format hard disk partitions, right click the drive you want to hide and remove the drive letter.
To show the drive, just add the drive letter back.

Note: You cannot change/remove a drive letter to a volume that contains System, Boot or Page File.
