自考本科什么专业好考:MP3里多出一个文件"FOUND.000"

先是插在电脑上拔不掉，重起电脑BOOTEX后发现多了个“FOUND.000”的文件夹和一个“BOOTEX”的文本文档。
文件夹里有1692个“FILE0000”“FILE0001”、、、“FILE1691”的类型是“Recovered File Fragments”的文件；
文本文档里的内容是-----------（以下）：
Checking file system on G:
The type of the file system is FAT.

One of your disks needs to be checked for consistency. You
may cancel the disk check, but it is strongly recommended
that you continue.
Windows will now check the disk.
