Permissions XAMPP:[错误]InnoDB:InnoDB#u系统数据文件'；ibdata1'；必须是可写的

我想制作自己的wiki供个人使用，并在外部驱动器上运行。我正在使用Windows10

昨天我将XAMPP portable安装到了外置硬盘上，并设置了MediaWiki，一切都很好。我在没有关闭apache和mysql的情况下关闭了计算机，今天早上醒来继续工作，但mysql无法启动。我还没有备份，因为我最近刚在昨天晚上完成了备份，所以我不会因为失去我写的几篇文章而感到太难过

我试着查看ibdata1，作为管理员，我应该完全控制它，所以我不确定为什么会出现这个错误

关于如何修复此问题，我有什么选择？

我在尝试将密码重置为MySQL时遇到了类似的问题。我正在使用Windows电脑。我进入管理工具->服务，然后停止MySQL任务。然后我没有收到错误消息：“'ibdata1'必须是可写的”
