My Liteon 812S read CD/DVDs only randomly. When u put a media in it just blinks a lot and then nothin. It started last week with 1 in 10 trys failure to 10 in 10 failures now. Winxp shows the drive as empty. It happens to all sorts of media frm CD, CDRW, CDR, DVD & DVDR. It used to work fine for the last six months. The only change i made last month was to add a new hard disk. I thought it had something to do with power so i unplugged the hdd but no improvement in the dvd-drive.
I hav a p4 3.2ghz with 512 ddr2 with winxp sp2
