Ok, I built a work PC over a year ago for work, but only had a 1TB SSD for everything. In an attempt to speed things up a bit, I picked up an M.2 during Black Friday sales and installed it, but had not been able to transfer Windows over because work was too busy to shut down my PC for a few days (due to reinstalling software, not transferring Windows). Finally had time to move my files and transfer Windows, but now my old drive has all the old partitions and won't let me reformat the entire drive.
I'd like to completely reformat the old drive and use it for all of my programs and let the m.2 be reserved for only running the OS. Can't figure out how to post the image after text, so please see above. Disk 1 is the new m.2, Disk 0 is the old 1TB SSD. Both are working but I can't figure out how to reformat the drive completely. Disk 0 had Windows on it originally. Any ideas? Also, is there a specific format I should use? First time poster, long time fan. Any help is greatly appreciated!
