I've been using the Sony BWU-100A Blu-ray burner for a while now. I recently updated the firmware to 1.0e from 1.0c... now I cannot rip Blu-rays properly anymore. I would like to revert the firmware back to 1.0c, but it won't work. I kept the "firmware updater" for both "c" and "e", but whenever I run the updater for c, it says, "A drive corresponding to this program can not be found." The drive is plugged-in, Windows sees it, I can watch Blu-ray, DVD movies through it. I assume that the firmware updater is checking if the current firmware is newer, if so it doesn't continue. Is there any way to get around this?
