My PC is new and I'm installing a Samsung 500 GB SSD. The HD that came with the PC is a 1TB 7200rpm HD & mostly empty, with the OSP Win10 on it now I have only used 78GB of the space. What I want to do is partition it to use most of it to become my internal back up HD where I store all my stuff, files, picts, video etc. I need to keep that HD in case I have an issue of some kind as my warranty runs for 4yrs from now. The SSD is 500GB so has ample room for my OSP & any Programs I may load. How do I go about splitting that HD now. I could copy or clone it to my EXT HD then install it back at a later date if needed but that seems like a lot of work or I could clone the Samsung back but if the motherboard is the problem that probably would not work so my 1st idea is probably best. How do I accomplish this.
