In the past, all the external HDs I've had, always shown the space
available to be less than the HDs specs. I have just finished setting
up a Lacie D2 Quadra 1TB HD, after getting rid of the Windows software
I have 999.3 GB available. What have they done different to the HD to
achieve this.

They have changed the way MacOS X reports disc space.

MacOS X 10.6 shows size in multiples of a thousand rather than powers of
two, which is what the HD adverts use by way of a capacity spec.

I /think/ this is a new thing for 10.6.

Depending on how recently you last did it, that's probably a change in
MacOS rather than a change in the drives. It changed as of 10.6 to
display GB as 1,000,000,000 bytes, matching the way hard disk
manufacturers specify their capacities.

It is. You have to watch out, though: 10.6 Finder reports capacities in
powers of ten, but third party applications may still be usign powers of
two, resulting in an apparent difference (7% out if the figures are
measured in gigabytes).
