Well, it's possible to reconstruct the label information for *that particular UFS file system*, since if you know the location of the superblock (or one of its backup copies), you can determine the offset and size of the FS. It won't tell you anything about *other* partitions though. > 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.
