我有 Windows 10，并按照教程中的确切步骤进行操作，一切都很顺利这里。使用 32GB USB 记忆棒时出错：访问设备被拒绝。这是日志：

注意：.iso 文件保存在我的“下载”文件夹中，而我的 U 盘是全新且空的。但是，当我将其放入时，我无法在这台计算机上对其进行格式化（尽管它可以在 Windows 8 计算机上运行）。昨天我用 128GB USB 进行了尝试，这可能太大了，它说该设备无法处理。
鲁弗斯有问题吗？
答案1
如中所示鲁弗斯常见问题解答有很多应用程序（通常是安全解决方案）可以阻止 Rufus 等软件访问 USB 闪存驱动器。
请记住，常见问题解答中的列表远非详尽无遗。
最有可能的是，您的电脑上有某个应用程序或服务阻止了对 USB 的访问，您可能需要找出它是什么。另一种可能性是您可能遇到硬件问题，在这种情况下，我强烈建议您运行坏块检查（Rufus 可以在 下执行此操作Show advanced format options）。
