So I have a 300gb external HDD that I've tried formatting (twice now). And it seems to always get stuck at 75%. I'm formatting through the "Disk Management" in Computer Management, if that makes any different. It's been stopped at 75% for a day now. I started yesterday, and before I went to bed it was at 75%. When I put my ear to the harddrive it does sound like it is still spinning though. So any help there would be appreciated, thanks.
