I built a pc a while ago and have been using a Samsung 128 SSD for my OS and storage. I just got a 1TB WD HDD and windows 8.1 and want to switch my SSD to ACHI mode before I format and do a clean install. I am just wondering if i can just switch it in the BIOS then boot up my windows 8.1 install to wipe the drive. I am worried about running into trouble or a BSOD. thank you!
