It will give a fairly strong hint, however. If you know what is taken up by this partition, you can remove it from the pool of available space and guess with a relatively high degree of accuracy that the next partition begins where this one ends. : > Is this trick possible with other : > kinds of file systems too? : : That's totally dependent on the particular file system. For instance, : a swap partition contains no metadata (that I know of), so all you can : do is deduce it's size and position from the sizes and positions of : surrounding partitions, and of the slice they're in. Yes. This is true.... That's one of the problems of my disklabel reconstruction program that tries to run fast... It slows way down when it hits the swap area...
