DVD-RW for ASUS M6VA (a.k.a. Z70VA)

Hello, I have an ASUS M6VA notebook which have a TSST TS-L532U DVD-RW drive, which does not work well (read DVDs but no CDs). I wish replace the drive by another one, but I don’t know what another drive can be compatible with the notebook (this have a hot plug-in bay)…

Any of you knows some drives equivalent for replace the old drive?

Thanks
