Dvd-R is recognized as Blank CD

ok my drive used to be working fine about a week ago

the drive is a Sony Dw-Q28A

and just today when i needed to burn an image file,my drive recognized my blank Dvd-R disk as a blank cd disk

i tried burning the image with nero and it kept saying wrong media inserted please insert a blank dvd disk

but then i tried burning the image as a normal data file and it worked as usual

another problem ive encountered is that my drive cant read most of the Dvd Rw disks that the drive itself burned

is there any way to solve this problem?
