My laptop wont read my disk drive.

One day out of nowhere my diskdrive on my laptop doesnt work. My laptop doesnt even recognize that it has a diskdrive attached to it. But when I go to the BIOS it says it is installed. But its not on my dvice manager. The diskdrive came installed with the laptop. Can someone please help?
Answer #1
if it boots into the OS and your able to access the device manager, the drive is working.
Seems like a software/config issue. del/create new partition + format and reload the OS to solve this in a matter of 2-3hrs + 5-18hrs in customization.
try something like UBCD and see if you can check if any of the sectors in the drive are bad, if any are bad, the drive is bricked and ya gotta buy new one / get new one from warranty.
