This process is called making a filesystem. Most UNIX filesystem types have a similar general structure, although the exact details vary quite a bit. The central concepts are superblock, inode , data block, directory block , and indirection block.
What are blocks in file system?
In computing (specifically data transmission and data storage), a block, sometimes called a physical record, is a sequence of bytes or bits, usually containing some whole number of records, having a maximum length; a block size. Data thus structured are said to be blocked.
What is a block in Unix?
The Unix file system allocates data blocks (blocks that contain a file’s contents) one at a time from a pool of free blocks. Unix uses 4K blocks. Moreover, a file’s blocks are scattered randomly within the physical disk. Inodes include pointers to the data blocks.
