This article is about the xp U disk can not be copied disk is written to protect the solution is how, the editor thinks it is very practical, so share with you to learn, I hope you can get something after reading this article, say no more, follow the editor to have a look.

It is believed that when many people are using removable storage devices, such as USB drives and removable hard drives, they suddenly cannot copy after plugging them into their computers, suggesting that the disk is write-protected. Please remove the thorny problem of write protection or using another disk.

At this time may be depressed for a long time, U disk is still good a few days ago, how can suddenly not be used? Is it a virus? Or is it broken? Use antivirus software to check and kill completely, but did not kill a thing to rule out signs of poisoning. Is it true that the USB flash drive is physically damaged?

In fact, this is a special "write protection" of U disk, not the traditional way of writing protection button on U disk, but using a new method. Windows XP SP2 introduces a security feature for USB devices that allows users to add "write protection" to the flash drive to prevent changes to the contents of the flash drive.

The method is simple: expand it in turn in the Registry Editor

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl], then create a new subkey named "StorageDevicePolicies" in the "control" item, and create a new dword value named "WriteProtect" under that subkey, and set its value to 1 (hexadecimal). Exit Registry Editor to take effect.

In this way, when others want to modify the data in the flash drive on our computers, a warning window will pop up telling them that the flash drive is write-protected.

Based on this write protection principle, we can easily remove the write limit on the flash drive, changing the value of "WriteProtect" to 0.

The above is how to protect the disk that cannot be copied from U disk in xp. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
