So this is a follow-up on my last post. Basically, my PC froze during defrag and now I can't even see the drive in explorer, isn't detected in BIOS, can't see the space on it, but I can see it in disk manager. When I tried to see the properties of it yesterday, I got an error message on the line of "disk I/O error". The HDD in question is actually 2TB, but whenever it tells me to initialize a new disk, it shows it's only some amount in MB or it gives me that message you see that popped up while I was typing this. Is there a way to reset the drive physically?
