What's unclear to me here is when these options would be needed. Is it only when the *data* wouldn't quite fit on the new drive, or is it used regardless when you're going from a larger drive to a smaller one?

So, would you use either option in this case:
Old drive 160GB (60GB used)
New drive 120GB

I did look in the manual but don't understand the example:

"For example, if you have a 250GB partition that contains 50GB of data and
requires 150GB of space to restore and you need to restore it to a 100GB
partition, you can compact the file system to under 100GB before imaging it
and then restore it to the 100GB partition."

How could 50GB of data ever require 150GB of space? Are you maybe talking about a 50GB (compressed) image file that when restored actually takes 150GB (i.e. there's really 150GB of data in the first place)? If so, that's a very confusing way of putting it.

rseiler,

Please see page 212 in the IFW user guide. Note the sector spread in table A.

In IFW you can get a measure of sector spread with "GiB to Restore"

OK, got it. I wasn't thinking of it in the move/optimization sense, just data used/space free.

You can do your restore like this:
1. Start IFW.
2. Select to do a normal restore.
3. Select the image of larger drive to restore.
4. Select the smaller drive as the destination for the restore.
5. Enable the "Scale to Fit" and "Compact Data" options. (Other options may also be required depending on the scenario.)
6. Perform the restore.
Does this only apply when restoring a windows partition?
I do not see these options when restoring a linux partition.
