The Read and Write Function of the File Structure Only Reads or Writes the Current Cluster

[zzjrabbit]

Hi! Thanks to this great crate, my OS supported FAT32 file system in 1 day. But today, when I was trying to read a user program from the disk, I found out that the read function of the file structure only reads the current cluster. Then I read the source code, and I also found out that the write function does the same thing. It only writes the current cluster. I thought that my builder program uses this crate as well, but it works pretty good. I checked it. Then I found the reason. It uses the core::io::copy function. To read my user program from my disk, I had to seek every time I read a cluster. It's so cumbersome. Could you please fix this bug?

Are you talking about the necessity to seek to the beginning of a partition before opening a filesystem (FileSystem::new)? If not could you provide an example code that demonstrates the problem?
