sounds like a power issue. try removing one of them and see if the other keeps disappearing.

Also, could you please explain why you wrote "windows 7 beta" as your OS?

that was a long time ago and i have not had a chance to change it and new1200 watt p/s
new dvd and blue ray new hdd its not a power issue unless its a deep power management issue and it
happens on multiple computers mutiple os's xp w7 w8... it happens every time i use dvd/blueray writeing software the drives return after i reboot and you can read any cd/dvd and run installes from them but not write if you do windows goes " DING " and they are gone...reboot they are back... every once in a while i can get away with making a dvd...its like there is a program monotoring the use of the dvd writer and if it detects the dvd writeing it shuts the dvd from the system resulting in coasters...it's driving me crazy...
