Smarter than me. *grin*

Bytes vs KBytes and rounding. I notice similar things with Windows explorer.

Probably.

Honestly, I would worry that it's going to be broken. When you destroy
the hda2 extended partition, hda7 goes away, and I don't think the
voodoo you plan on trying will keep it there. I might be wrong, but if
it isn't, it might ne worth scp'ing a tar of the directory/partition
up to a fileserver with enough space for it. Because I know from
personal experience that if it's gone, it's *GONE* if you don't ahve a
abckup, y'know?
