How to disable the optical drive in Bios

How to disable the optical drive in Bios

To protect the security and trade secrets of computer files, you may need to disable the use of USB interfaces on your computer and the use of storage and read/write tools such as USB flash drives, mobile hard drives, optical drives, and soft drives. However, the storage space of the optical drive is also considerable. You can use the optical drive to burn a CD file that can store hundreds of megabytes of data. You can use the optical drive to burn a DVD file that can store several GB of data, therefore, if you do not control the use of the computer optical drive, it will also bring great risks to the computer file security.

Then, how can we effectively disable the use of the optical drive, especially the function of burning the optical drive, this article summarizes several effective ways to disable the use of the optical drive, disable the use of the optical drive through the BIOS, disable the optical drive in the registry or the Device Manager to disable the use of the optical drive.

Method 1:

1. disabling the use of optical drive via BIOS is a common method and the operation is relatively simple. Press DEL to enter BIOS settings, select "Standard COMS Features", and press enter, as shown in:


 
Then, move to a CD/DVD entry, press enter, select "None" from the pop-up extended panel, and press the Enter key again. As shown in:
 

In this case, the CD/DVD item is set to None. As shown in:


 
2. Disable the optical drive and block the optical drive using the registry:

Click Start-run, enter regedit, and press enter to open the registry key: HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer branch, create a double byte value "NoDrives ". Modify this value. In the DWORD Value editor dialog box, select the "decimal" radio button in the "base" grouping box. In the "data" editing box, enter the drive letter you want to hide and click OK, after the system is restarted, the corresponding drive is hidden. Note: here we use the Npower of 2 (N = 1, 2, 3 ,......) To represent A drive letter, for example, A is 1, B is 2, C is 4, D is 8, E is 16, F is 32, G is 64 ...... Also, if you want to hide drive A, drive B, drive C, enter 7, because 7 = 1 + 2 + 4.

3. Use the Device Manager to disable the optical drive and block the optical drive. The method is as follows:

First, find the "my computer" icon and right-click "manage" to enter the Computer Management menu, as shown in:


 
Find the "Device Manager" in the displayed "Computer Management", as shown in. The current computer devices are listed on the right, with the DVD \ cd drive, as shown in:


 
So far, we have completely disabled the optical drive. However, whether you use BIOS, registry, or "Device Manager" to disable the use of the optical drive, you can use the operating system settings to disable the use of the optical drive, this means that once an employee uses the reverse modification method, they can also re-enable the optical drive and re-use the optical drive. Therefore, the above method has certain risks, you cannot completely disable the optical drive. In this case, you can consider using third-party software to completely disable the use of the optical drive and shield the purpose of the optical drive.

Method 2: Use the dedicated computer security management software and disable the optical drive software to completely restrict the use of the optical drive.

At present, there are many specialized computer security management software and computer device disabling software in China, which can completely prohibit the use of computer optical drives and other devices. At the same time, due to the integration of powerful self-protection and real-time monitoring functions, it can also prevent the drive from being re-enabled due to reverse modification. For example, there is a "Disable software from USB port", which is a software that specifically prohibits the use of USB interfaces on computers, shields USB disks, and prohibits the use of mobile hard disks. It can also completely prohibit the use of optical drives, the operation is also very simple, just tick it. As shown in:

In addition, the portable to USB disabling software can also shield email attachments, block attachments uploaded from online storage, block FTP uploads, and prohibit sending QQ files to fully protect the security of computer files, prevent leakage through various channels.

In addition, USB control software can prohibit modification of the Registry, prohibit modification of group policies, prohibit modification of startup items, prohibit the start of the Device Manager, prohibit the start of the computer from the PE disk, prohibit the drive to start the computer, etc, prevent re-enabling the optical drive by bypassing System Monitoring in various ways, which greatly protects the security of computer files.

In short, whether it is through the relevant configuration of the operating system or through specialized software, you can achieve the limitations of the Computer Optical Drive, the specific method used, you can choose according to your own needs.
