Full vs Quick format for Truecrypt

[BirdDad]

I have been doing full formats so far with TC. Is there anything bad with changing to quick format?
The time it takes my i7 quad laptop to FF a TC volume is about eight hours.
What would be the disadvantages of doing a quick format?

Quick Format

If unchecked, each sector of the new volume will be formatted. This means that the new volume
will be entirely filled with random data. Quick format is much faster but may be less secure
because until the whole volume has been filled with files, it may be possible to tell how much data
it contains (if the space was not filled with random data beforehand). If you are not sure whether to
enable or disable Quick Format, we recommend that you leave this option unchecked. Note that
Quick Format can only be enabled when encrypting partitions/devices.
Important: When encrypting a partition/device within which you intend to create a hidden volume
afterwards, leave this option unchecked.
