How is filesystem information stored on the hard disk












0















When we format a partition in a hard disk with a file system using mkfs -t ext4 /dev/sdb1, what's the data that is written on to /dev/sdb1.?



Some data identifying the filesystem type has to be written on to the partition. What is this data and to which area of the partition this data will be written.? I think that this data about the filesystem is required by other computers to identify what is the filesystem on a partition.
