DELL 700m's DISK DRIVE SONY DW-56A

MY DELL 700m’s DISK DRIVE SONY DW-56A just stop reading cds one day and i tried to all kinds of stuff to it but it just would not read. So I ended up reinstalling the operating system on it using a external disk drive, after installing when I look up in the device manger the drive says

"SKNY DRD -@52A " that is what it says on bootup also. I tried my friends sony DW-56a on my computer and it works fine. I tried download the firmware for it but it says I cant flash it because It does not recognize the drive, does any one have any solutions to this problem.
