How about hiding two or more drives using Windows Registry?

 

It’s easy! Just add the two or more values: Let’s try drive F and I.

(9 – 1) = 8   and 2 raise to 8 is 256

Therefore, F + I = 32 + 256 = 288

Using the value of 288 it will hide the Drive F and I.

 

Note: Remember to set the value in Decimal.

Another example is hiding the drives C and E => 4 + 16 = 20
