It sounds like the drive is failing.
Hey, just for the sake of technical knowledge... can any one tell me what makes the drive go fail...
and how is it able to read some cd and some not. It clearly means that the physical lens condition may be working as it is able to read. so it might be some sw/firmware problem..
Does the Drive has different mechanisms to read cd and dvds? Well It definitely be having some differences of reading diff Disk formats like UDF data/ raw data..etc
Any knowledge contribution is welcome
