Losing hard-drive space

I have "secure empty trash" at least 10 gb of data over the past week, but i am not getting any of my hard-drive space back on my Macbook Pro. i had 23 Gb left on my hard-drive, and now its down to 13 Gb, but i have deleted alot of data (at least 10 Gb) and i am not getting any hard drive space back. i have boot camp installed and file vault turned on.

I was waiting to see if anyone using File Vault would reply but I see that no one has. So, I will ask a secondary question. Does File Vault create an encrypted virtual volume, or does it simply encrypt on the fly?

If an encrypted virtual volume your file deletions would impact the contents of that volume, but the size of the volume would stay the same. Hence OS X would report no net savings in actual disk space.

Is this possibly the issue? I don't use File Vault so I cannot say.

i am not sure. on my powermac G5 i have filevault also turned on and everytime i should down the machine it prompt's me for vilefault (skip or continue), so i always hit "continue" and it does its thing and then powers down. However on my Macbook Pro it has never prompted me and i have file vault turned on.

I hate FileVault. It took up a ton of valuable space on my machine and since it's unneccacery for me I turned it off.

I would tend to agree. If you need encrypted protection, create an encrypted volume (.dmg) file and use it. Here is the HOWTO from Apple:
