I upgraded the Firmware on my Ricoh MP5120A from 1.34 to 1.50. Since doing so the writer have lost the ability to recognize silver/gold dyes. Blue/Green dyes are still recognized. I have many CD-R disks burned with data on them that the burner no longer recognizes. Has anyone else had this problem? Does anyone know a solution to this problem without having to but a cheap CD-ROM drive?
