IDE DVD-ROM 16X and MITSUMI CR-48XATE

Hiya, I am having trouble with my DVD/CD-ROM drive and in the device manager it says they are them. It will not read CD-ROM’s or DVD’s any more and I have no idea why. It reads only one game out of many which I have tried. I have cleaned it as best as I can from the outside but it takes 3 attempts to read the one game it will read. Does any one have any ideas at all, or have expeirienced problems with the same devices? Thanks.
