让U盘只读取数据不写入的小方法

更新时间：2026-08-23 04:50:44 | 编辑：颜若惜 | 信息来源：互联网

　　对U盘来说，读取数据和写入数据时相辅相成的两个基础功能。没有写入数据，就没有数据可读取。不过，有时候出于某些原因我们会希望U盘只读不写。该如何操作呢?让小编来将这一U盘教程与你分享。

　　u盘，因其小巧的体积、携带方便的特点，使之受到大众的欢迎。也是因为这一特点，部分人电脑上的文件数据可通过它不知不觉的被窃取盗走，但由于平常工作时又会经常用到u盘，无法通过禁用u盘的方式进行解决。那么我们该怎么办呢?下面就教大家如何防止在电脑上让u盘只能读取而不能写入。　　

　　复制u盘出错

　　1、首先打开计算机，依次点击桌面左下方“开始”→“运行”;随后在出现的窗口下输入“regedit”后按回车键确认。在弹出的注册表编辑器中依次展开HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies选项即可;如下图所示：　　

　　注册表编辑器

　　2、在右边找到WriteProtect选项，并将其值设置为“1”即可完成设置u盘只读不写的步骤。若你找不到WriteProtect选项，则需要在右边的窗口下点击右键新建DWORD值并命名为WriteProtect，同时将其数值设置为“1”即可。

　　完成以上的操作后，赶紧插上u盘试试效果吧!若你想要恢复u盘的写入功能，只要按照相同的步骤将数值从“1”改为“0”即可。

　　设置好后，现在所有U盘在这台电脑上就只能读取数据不能拷贝数据了，对在一定程度上会将强电脑内部数据的安全。如今U盘成为大众必备的工具之一，在方便的同时，也需要注意防范数据安全。

　　最初的拷贝资料、电影等的工具，变成装系统辅助工具，如今学习了本教程，又知道U盘还有一个神奇的功效——xp系统下做到只读不写的，所以有空没空多来u大侠官网逛逛，就可以学到更多的东西。
