The metal might consist of RAM or hard disks, but in either case, file system data structures organize the sectors and bytes formatted by the hardware manufacturer.
原始材料可能由 RAM 或硬盘组成，但是不管是哪种情况，文件系统数据结构都是组织由硬件制造商格式化了的扇区和字节。
The other useful thing is that you can have multiple partitions, each formatted with a different “file system.”
另一个分区的好处是，你的分区可以有各种各样的不同文件系统。
It turns out that the Root 1 file system isn't even formatted; it's just 256 MB of null bytes. But the Root 2 file system is golden.
这显示Root 1文件系统尚未格式化；它只是256 MB的空字节。
