I'm implementing EXT2 file system

Today, I was implementing Ext2 file system.
First, I defined some ext2 structures and statics strings.
Next, I implemented read super block from first block group. Here had very important information. Second block group's super block had backup information.
Then, I implemented read many block. but I failed that. First block was read own implementation but, It couldn't read over next blocks :-(

I understood ext file-system.
First, I will define structure the super block. super block is putted on after boot sector.
Next, I will define structure the block.
Then, I will write super block after check the block information. block information was checked file system codes from physical block device.
I'm going to try to implement file system functions.
also, I should implement system call accessed physical block device by assembly-language.
