A friend installed a Liteon Super Allwrite DVD Writer in place of his Combo. His OS is XP Home Edition. On bootup the activity led did not flash, and he couldn't open the tray. When we re-booted the light flashed and the Tray opened as normal, and the writer functioned properly. I re-booted seveal times and everything was OK. I shut down and tried a cold boot, the problem was still there. I went into the BIOS and it seemed OK,ie set to Auto detect, exited the BIOS without saving, and as the startup continued, the activity light flashed and the tray could be operated. The writer only works after a re-boot or going to Bios and then continuing the setup. Can anybody help please.
