Hello, I had a fast 36GB hard drive for my system. Recently the drive died and I bought another one but this time 72GB. I restored my system and Acronis True Image created a 36 GB partition leaving about 36 GB free space. My question is whether it is best to leave this or to enlarge the partition size to fill up the entire hard drive? If I leave the partition size at 36GB that will presumably restrict the area of the drive used by Windows. Will this reduce the need to defragment and reduce ware and tear on the drive or will it make no difference? I know almost nothing about the technical aspects of how a drive works and the best practises on whether to partition or not. Hope someone can enlighten and advise me.
