I have a friend with a windows 98 computer and he wanted me to install a hardrive in his Compaq desktop for him. I had already done this once with Win XP so I knew how. I hooked it up, but then I realised that my hardrive didn't have those things on it that tell it if it is a master or slave harddrive.(It is a used one I pulled out of another computer I hadn't used for a year) I used those things for another harddrive that didn't have it. I plugged it in anyway and the bios detected it but when I went to My Computer in Windows 98, it wasn't there! Is it because I have to install a driver for it? Is it because it doesn't know if it is a master or slave? I don't know. Please HELP!!!!!!
