📎 AI Summary:
The user is experiencing intermittent issues with their Dell E5500 laptop's DVD-ROM drive, which appears briefly in Device Manager and then disappears, showing error codes 45 and 10, and occasionally requires a data CD to function temporarily. They confirm BIOS is set to ACHI mode and have ruled out registry filter issues. A suggested solution was to change the BIOS setting back to IDE mode, but the user indicates it is already set correctly, and they find the behavior unusual compared to common problems found online.

Dell laptop E5500 running windows 7 x64.

DVD ROM appears in device manager after start up for a few seconds then disappears. Showing Error Code 45 (not connected to computer)

Earlier this evening it also showed error code 10 (device cannot start)

Opening and closing the tray prompts it to show in device manager but again for only a few seconds.

Loading a data CD will get it to run and it works for as long as it is being used then disappears from device manager again.

Is there a setting that is incorrectly configured?

This not an upper and lower filters problem - not in my registry.
BIOS set to ACHI mode

Did you set this yourself? My first guess would be to change it back to IDE.

I do not have Win 7 available right now, but you can do that for individual devices...?

IDE / ACHI BIOS setting

No that's how it was. I was going to try then found it set as suggested on another forum.

Thanks anyway.

It's just very odd that the drive appears to work and appears in device manager when in use but then disappears from device manager and system tray seconds after usage ends. Slightly different, I think, to all the other scenarios I read about on the web.
