Registry-how to hide and remove hard disk partitions-a tip

Symptom: Hard Disk Partition hiding
Test Description: log off or restart to take effect.
Registry Key Value: HKEY_CURRENT_USER/software/Microsoft/Windows/CurrentVersion/policies/Explorer/nodrives

Set the key value to ffffffff.

When you hide a drive letter, it is generally set by software. If you need to manually change it, I am afraid you do not know how much the key value should be set. Here is a detailed explanation: Open the registry and go to the following path: HKEY_CURRENT_USER/software/Microsoft/Windows/CurrentVersion/policies/Explorer/ Create a new key value nodrives. The key value of this key is the key to hide the drive letter. Below is a hidden value example table (Binary ). Drive letter A B C D E F G H Value 01000000 02000000 04000000 08000000 10000000 20000000 40000000 80000000 Drive letter I J K L M N O P Value 00010000 00020000 00040000 00080000 00100000 00200000 00400000 00800000 Drive letter Q R S T U V W X Value 00000100 00000200 00000400 00000800 00001000 00002000 00004000 00008000 Drive letter Y Z Value 00000001 00000002 Let me explain it. I also used a lot of time to study it. We should regard these values as four zones, 00 00 00 The first zone controls the drive letter a-h, the second zone controls the drive letter I-P, the third zone controls the drive letter q-X, and the fourth zone controls the drive letter Y and Z All the time is in a multiplier relationship, for example, disk A is 01, disk B is 02, and disk C is 02*2 = 04, but after disk D is 08 The hexadecimal computation (don't tell me you don't know what the hexadecimal computation is), so the 08*2 of the edisk is 16. If you enter one, you need to write it into the edisk 10, and then proceed. F disk 10*2 = 20 ....... To hide two partitions, add the values. For example, to hide both disk A and disk F, the value is 01000000 + 20000000 = 21000000. If you want to hide all the disks in this zone, write them as ff (hexadecimal last bit) The subsequent disks are computed in the same way. Also, if you write the DWORD Value, You have to reverse it. The four zones are the opposite, for example, disk. If you want to write it as 00000001, I want to write it as 00000100. We suggest you try it first, and you will be more impressed.
