USB flash drives have become very common in our lives. Because they are easy to carry, many people like to store important files or data in USB flash drives. However, they are worried that the important information inside will be modified or copied at will by others. However, we cannot store USB flash drives. If it is disabled, is there any way to lock our USB flash drive to prevent the security of the files inside? , today the editor will teach you how to set the read-only mode of the USB flash drive to add a layer of security protection to our USB flash drive.
Option one:
1. Open "My Computer" → "Tools → Folder Options → View" command → Uncheck "Simple File Sharing" under the "Advanced Settings" option
2. Right-click the U disk and select "Properties" → Go to the "Security" tab → Set the permissions of Everyone under "Group and User List" to "Read Only", "Read and Run", and "List Folder Directory" "

Option two:
We are running Regedit on an XP SP2 computer. We select a new item under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl and the name of the item is StorageDevicePolicies.
Set the WriteProtect value in StorageDevicePolicies to 1, so that our USB disk can be turned into read-only mode (if we want to return to normal, we can guess the method of setting the WriteProtect value to 0).
Tip: If the "StorageDevicePolicies" registry entry is not found in the registry, you can right-click the "Control" registry entry, create a new registry entry named "StorageDevicePolicies", and then create the value of WriteProtect according to the above method That’s it.
Now we can test it and send the USB disk file to the USB disk
A prompt box pops up: The USB flash drive shows that it is write-protected, so our read-only USB flash drive is successfully set.
