Is my drive dying slowly?

Hi fellas. I have a Liteon 48125S with the latest firmware. Well, in the last week it started to give me problems with writing, in fact if I try to burn my cds at high speeds (40x-48x), this is the usual result:

The media I use (traxdata silver 48x) aren’t of bad quality, I also tried to use my father’s cd-rw drive (a liteon 48126) and it burns them without problems (no C2 errors).

My drive hasn’t problems in reading or writing below 32x-24x.

So guys, do you think it’s the laser which could be not clean (and maybe I could use one of those cds that clean the laser), or it could be more a mechanical problem in the drive?

Thanks for any answer!

It couldn’t hurt to clean the laser.
