It increases with the number of blocks and inodes in use mostly.

These days you have absolutely no guarantee that a partition is in the location on the disk where the cylinder numbers imply they should be. Disk manufacturers are free to put the bits of a disk that add up to this mythical thing called a "cylinder" any place they like, as long as the mapping between them is maintained. There is also no way I know of to ask a disk where a specific sector actually resides. -- alan dot mckinnon at gmail dot com
