Our hard drive has been going out, so we purchased a new one and installed it last night. We installed our OS and security software, downloaded the drivers that we needed for the printer and the scanner, but this whole path has been fraught with difficulty. First of all, our new hard drive is recognized as the F drive by the computer, and the C drive is now called a removable drive. When we run our anti-spyware scan some of the files from the C drive come up and it says it cannot read them unless we place the disk in the drive. So, we just skip those ones. But now our DVD and our CD are not reading/working. I am about ready to just go buy a new computer, but don't really have the money for that. So, I have two questions. First, do I need to be worried about the files still remaining from the C drive? How can they even be on there if the c drive (old hard drive) is not in the computer? Can we remove those, or can we move them to the F drive? Second, why is the CD and DVD players/burners not working? The DVD said something about not being compatible, so should we download new drivers? Please forgive my lack of knowledge, we are somewhat computer literate, but our computer guy moved away and assured us that we should be able to install a new hard drive and the OS without too much difficulty. I did not think it would cause this many problems. I homeschool and my kids use the PC for school, so the sooner we can fix this the better. Our computer tower is a Dell, I do not know what brand the hard drive is.
