Frankly speaking, I'm using Windows all the while, and I'm about to format my hard disk to make a clean installation for Linux. I wonder if I shall defragment my hard disk before formatting it. Some people say that it is not important because the Linux file system is completely different, which is good enough to take care of the hard disk. But in my confusion, I thought Windows has created lots of fragmented clusters along the way, wouldn't it be necessary for me to defragment my hard disk in the first place? Many thanks.
