Ok, I have a weird issue with my new HDD.
I have no understanding about HDD's at all so.. thats why I ask you guys :)

I have 1 partition on my HDD, C:.
My HDD is 640 GB (showing 596 though) but here is my problem:
It says I've used over 146 GB already but if I count all GB from every folder (including hidden) I come on ~60gb.

I saw that I used 121gb before I defragmentated, after the defragmentation I am using 146 GB.

Im using Vista Ultimate 64bit if thats of any you to you.




How can this happen, thank you in advance :)

Now it went from 146gb used to 141gb used...
What the hell is going on, I played Crysis (changed graphic options) and then my storage went from 146 to 141....
