I have a compaq presario 900 laptop with a H*L Data Storage (Hitachi/LG) CD-RW/DVD Drive. A DVD will play every time no problems, however any cd will not, even cd's I have used in the past will no longer play. When inserted it makes clicking sounds like it is tring to read it but after 30 sec or so it just stops. When I click on the drive it does not show a disc is there, just nothing. I've had this prob for over a year and am getting frustrated...aaarrrhhh . I asumed the drive was bad so I bought a new one (identical) but it did the same exact thing. This would logicly suggest that its not a hardware prob. Driver says its up to date, diagnostics show everything is installed and working properly. Any help would be appreciated. I also deleted the high and low filters in the registry, that did not change anything. Problem possibly started after reloading Roxio 5.0 but not sure.
