It increases with the number of blocks and inodes in use mostly. Which |
16 |
generally does equate to bigger partitions take longer as they have more stuff |
17 |
stored in them |

These days you have absolutely no guarantee that a partition is in the |
24 |
location on the disk where the cylinder numbers imply they should be. Disk |
25 |
manufacturers are free to put the bits of a disk that add up to this mythical |
26 |
thing called a "cylinder" any place they like, as long as the mapping between |
27 |
them is maintained. There is also no way I know of to ask a disk where a |
28 |
specific sector actually resides. |
