My computer has lost the d drive. I have a Compaq Pesario 5461. I was having trouble installing a game and downloaded a new driver from the Compaq website. It apparantly was not the right one and the computer would no longer reconize the d drive. I was getting "d: device not ready". I contacted Compaq support who advised me to delete the cdrom from properties and the computer would auto detect it. It hasn't. I have tried taking the cdrw completely out and putting it back in, but it still doesn't auto detect it. It is completely out of device manager and won't reinstall. I searched this site but I'm not sure exactlly what to do in bios to correct.
