After just a few steps, your USB flash drive data can only be read but not written, preventing the leakage of important data on your computer. Let’s take a look with the Huajun editor below.

1. First, we will demonstrate how to create a read-only USB disk on an XP computer. First, run Regedit on the computer. We select a new item under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl. The name of the item is StorageDevicePolicies.

2. Select a new DWORD value under the newly created StorageDevicePolicies. The name of the DWORD value is WriteProtect.

3. We set the value of WriteProtect to 1, so that the U disk can only perform read operations; if the value of WriteProtect is set to 0, the U disk can perform normal read and write operations.

In this way, if someone wants to copy important information or folders in your computer, the above error dialog box will appear. The effect is very obvious. This will not only prevent others from copying your computer data, but also effectively Resist virus attacks and get the best of both worlds. Just three simple steps to successfully create a read-only USB flash drive. Try it now!
