Recently my parent's Dell computer has been getting slower and slower on boot ups but after waiting for like 30 min. it works all right. i never found out what the problem was but today when i tried to play Steam which is installed on a secondary hard drive, it said it couldn't find it. So when I double-clicked on my F: drive to see what was going on in there, I get an error that says "The disk in drive F; is not formatted. Do you want to format it now?". Should I format it and will I lose all of my data that was on there before. And if anyone has a solution that would be great. Thanks ahead of time.
