Has anyone got firmware/drivers for DIGITAL MAX

I got a ]Digital Max[/B] brand DVD RW about a year ago. It worked great until about a week ago and went south on me. The phone # and the URL that came with the drive are unknown. I have lost the install disk. I can find NO info on this brand name. I took a peek inside and the only name that I could see was SONY but no other info. The drive shows on my system info as DVDRW DRW 3S163.
It is listed as a 16X +/- R +/-RW Double Layer drive. Any info that anyone has would be greatly appreciated. I am hoping to find some firmware and drivers that I can re-install to breathe some new life into this *&5$ thing…
