well have a interesting problem. Which probly started two years ago. One of My Customers called in saying his cdrom drive will not open and so He restarted the computer. So I went out on site and found that the Belt that opens the Drive up was broke. No problem Replayed The CDROM drive booted the system. Checked everything out and left.
About 9 months later the same customer called saying almost the same thing. Drive will not open. ("thats weird" ran threw my head") So went out on sited and found the same thing, CD Rom tray Belt broken. Talked to customer for a little bit asking him how much he used the drive, which was not much. How he open and closed the drive Etc... So being the drive was under warranty I replaced it again, but this time with a different make.
Then four months ago he calles again saying its doing it again. Went out replaced the drive. ask him if he was having any other problems with the computer which was no. Two months ago same thing. and today. every time its the same thing the belt that drives the cdrom tray is broke. and closer look at the broken belt it is all cracked and brittle.
the room is on the Third Floor, The heat is set to a conforable temp. its not a very dirty enviroment, The computer runs all week and gets shut down on friday. and turned back on Monday. No Cds are stored in the drive. he presses the eject button to open and close the drive. I have tried 4 different brands of drives in this computer.
The only thing I can think of is there is a Ozone Purfier in the room that is turned up all the way. I whould like to blame that but I don't know anoth what ozone will do, to be able to point the finger.

all the alarms in my head are saying its the eviroment. But maybe I am missing something. Any Sugestion would be helpful.
