So what happened right before you noticed this? Is it possible that you actually used up so much space without noticing?

Well i figured the issue.. i had windows 7 ultimate 64 bit, before. then i installed windows 8 pro 64 bit, and i made a backup, so i don't lost all my files etc. and then i used it on my lg external hdd. so then it happend.. 31 GB..... i used my hdd on another pc. still the same size.. 31 GB. i formatted, and again the same.. 31 GB...

i don't know what to do...... ;(
