RE: What is the structure of file system.At the time when we create a partition how the blocks are allocated.
At the time of buying the hard-disk you will have full 80 GB. but after you format it you will see that the size is reduced to 78 GB or so. That is bcoz the entire hard disk is divided in to several sectors and each sector is classified as Data section and Address section . This address section constitutes some bytes and hence al together you may lose some 1 or 2GB.
The OS or the file systems of OS are responsible for these address translations.
The device driver translates the block address to physical address [track sector etc. ]

Thus the file system would set up several tables for denoting the free sectors for denoting the sectors for a particular user etc.
