可以这样说，除非极少数特定主控芯片的特定U盘能找到这样的软件实现即时硬件级只读与解只读外，99%的U盘都没法实现。软件只读就是在目标计算机上运行一个注册表导入，也确实能实现U盘只读，但实际上效果不一定好。因为你要把这个注册表文件（网上可以找到）存放在U盘上，到网吧电脑上后打开U盘运行它才会让U盘变只读，可惜，你插入U盘后就可能已经中毒了，所以软件的只读效果不佳。出一个没办法的办法：无论如何不双击我的电脑－双击U盘的方式打开U盘，改为在我的电脑上右击选择资源管理器的方法打开U盘，因为只要你双击了硬盘（或U盘）盘符，就可能会激活病毒。
不需要软件，方法如下：
右键点击桌面空白区域，新建一个记事本文件。
-
然后打开记事本将下方的代码复制到记事本里面，点击保存
@echo off reg add HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /v WriteProtect /t REG_DWORD /d 00000001 pause
右键点击记事本选择重命名，将其后缀名更改为【.bat】类型。
插入U盘，双击新建的bat文件（批处理文件），等待操作完成，U盘只读模式设置成功。
驱动精灵 超级加密30000采用先进的加密算法，真正的达到了超高的加密强度，让你的加密数据无懈可击。并且速度也特快，每秒可加密25 — 50M的数据。文件、文件夹加密后，双击它，会弹出密码输入对话框，只有输入正确的密码才能打开该文件。使用完毕退出以后，它自动恢复到加密状态，无需再加密。把文件夹和文件直接加密成Exe可执行文件。你可以将重要的数据以这种方法加密后再通过网络或其他的方法在没有安装[超级加密 3000]的机器上使用。
磁盘保护功能
将您的软盘、硬盘和光驱等所有驱动器有选择的隐藏和加锁。并且可以禁止使用USB设备或只读使用USB存储设备。
域之盾软件支持对插入电脑的U盘批量一键设置只读，适合企业用户使用。软件还有U盘白名单，禁止插入U盘等等很多功能。
