You could copy your small disk image onto the beginning of your hard disk, fixup your partition tables by running fdisk and disklabel, and perhaps expand some of your old file systems with the growfs command, but I advise against it. It would be easier, though perhaps slower, to use fdisk, disklabel and newfs to create new partitions and file systems on the new drive and to copy the old file systems with dump/restore. If you do it this way, the files in the new file systems will be much closer to contiguous (a good thing). It will be much easier to expand the size of file systems other than the last one on your old disk. You will have the opportunity to reorganize your file systems and the new file systems will be better organized internally. I gather that the disk you intend to copy is a bootstrap disk. Don't forget to install the MBR bootstrap and the FreeBSD slice bootstrap. You might find it most convenient to create the new disk slices and FreeBSD partitions with /stand/sysinstall. I recall that there is an underdocumented "W" command that you can give when in the disk slice and partition creation menus that will cause the new partition tables and bootstraps to be written when you exit the menus so that you don't have to do an installation "commit". I usually do this kind of thing when booted from FreeBSD installation media, but I gather that it works ok when running multiuser. The man page is "sysinstall".
