SONY FX805 DVD/CD-RW PROBLEM- HELP!!!!

[PRESIDENT01]

or B-(
My sony laptop DVD/CD-RW does not seem to read my data cd's - I've been using the same backup CD-R disks for a few years now . But all of a sudden it cannot read any of them. It plays DVD's and reads other data CD's ok, but for some reason it will not pickup my old data CD-R disks. I've cleaned the cd's several times- All the system does is show a blank CD with no information on them. its a SONY VAIO FX805 MATSHITA UJDA730 DVD/CD-RW.
