Help.. LG GSA-4120B can't read CD

Dear CDFreakers,

Since last week, my DVD R/W drive can’t read/detect any CD. But for DVD, reading and writing goes normal as usual.
I dont know what happened, everything seems just OK before. I just noticed this error when I tried to burn a CD. I rarely use this drive to burn CD.
Please kindly help :bow: . Thanks in advance. :iagree:

DVD drive : LG GSA-4120B
Firmware : A112
OS : WIndows XP
