@@Knight Hadron,
well... I will not use my backup HDD for something like that... the less that one is used, the longer it lasts, and I cannot afford losing everything (like my passwords for over 300 websites and services)
So I still have:
C Partition, System (50GB free)
E Partition, Recordings (230GB free, but I record ~500MB/minute so that fills up quite fast)
F Partition, Games & Programs (80GB free)
I guess I could install it on F... but I don't like to see when my HDDs go red in windows ._. I already hate it so much when there is less than 1/3 of the HDD free... I even uninstall games to keep over 1/3 of my F Partition free (which is currently not, should uninstall something) It's like a obsession, I CANNOT fill a HDD to more that 2/3 ._.
