So I've scoured the internets lately searching for a solution before I finally decided to post a question. My problem is that well, to start broadly, the computer doesnt format anymore. I dont know why, but it gives me this error message. My dad somehow formatted it for me, so that it began working like new, with a new background but all my stuff intact. I'm not totally sure how he did this. The DVD-RW had stopped working before, as well, it dissapeared before, and after my dad formatted it, it showed up. It worked well, then my DVD-RW drive dissapeared from the my computer menu. In Bios next to ATAPI, nothing shows up. I check in the device manager, and it says that the DVD-RW is working fine. Now I'm not sure why it shows up in the device manager but not in the BIOS, but I dont know much about BIOS. I assume this is happening because I sent my computer back to the manufacturer because the DVD-RW drive broke previously, and they sent it back after a week. It worked for a couple months, then dissapeared. Its the DVD-RW drive that came with my Laptop, not an external one. Can someone help me?
