In the following tutorial, I explain how to hide a drive or drive letter from being displayed in My Computer. This is useful if you don't want just any average user to be able to easily detect, access and navigate a hard disk that is attached to your system.

#1. This Method is by DOS

1. Go to Start, then select Run
2. Type cmd to bring up the Dos window
3. Type Diskpart
4. In the diskpart mode, type list volume
5. As at now, you should see the list of your volumes,their letters,capacities etc.
6. Select the drive you want to hide by typing the following without Quotes;
"select volume X" (where X is the number of that drive you are hiding)
7. After it is selected, type Remove letter X(where X is the letter corresponding to the drive you are hiding) on the next line

At this time, your drive won't be showing anymore.You can now exit DOS
9. Follow the steps up to the last but two (7)
10. Type Assign letter X to show the drive again.
