Suddenly My Moserbaer LightScribe DVD Drive is not shown by Win XP from yesterday.
and its taking a long time at startup.
I have to manully select the Boot drive as hard disk.
If its getting detected sometimes then there's 4 possibilities:
Change the sata cable.
Try with a different sata power cable.
use a different sata connector on the mobo.
Your dvd drive is on the verge of dying.
