Hello Benquees! My DVD 400c (FH04) was fine until I responded to the popup - "An upgrade is available for your DVD drive" from HP. (KH27) was flashed to the unit AND NOW THE BURNER DISAPPEARS FROM THE SYSTEM WHEN DVD SHRINK IS RUN. Reboot and the Drive reappears. I tried flashing back to (FH04) but "HP is unable to verify..." Since when does an upgrade DOWNGRADE our systems? I also tried DOS flashing and I get an error during the flash. I'm considering pulling the unit and attempting to flash on my other machine. Had successful burns with all Generic and Branded disks (4x, 8x). Any suggestions (besides not trusting HP)? Seems to be the same unit SCAN80269 has.
