Well, suppose you have the old hda (40G), and you back it up into a 40G
file, then you replace it with a 60G drive. Then restoring should work
(not writing the last 20G), and Linux should see a 60G hda with a 40G
hda1, which is OK. The partition table (in the first 64(?) blocks) will
specify that partition #1 takes up the first 40G, which used to be the
entire disk, but is no longer.
If this works, you can try making the remaining space into hda2,
creating a filesystem on it, and mounting it somewhere useful.
IANAGuru. I haven't done this. I _have_ dealt with filesystems smaller
than their partitions (no problems), so that's a start.
