设备环境：某RK3566 T 物理机、局域网、系统294
BUG现象：某RK3566 T 挂载机械硬盘，硬盘独立电源，sata转USB接入USB拓展坞。已经正常创建btrfs空间，并通过相册上传了大量照片，使用正常。后陆续机械硬盘会出现硬盘移除情况未挂载，重启后有时候会正常，使用过程中有时候会突然出现未挂载。 后有一个固态硬盘插入USB拓展坞，创建btrfs空间后正常使用，重启后机械硬盘无法挂载，反复重启多次也是显示3.6T的机械硬盘未挂载。去掉固态硬盘启动机械硬盘还是未挂载，固态硬盘就无论怎么样启动都是正常挂载的。此时去创建存储空间能对机械硬盘创建存储空间，选到机械硬盘（但是需要格式化肯定是不能去做）。
出现频率：必现
