CDRW not detected

  martjc 13:47 06 Oct 2004

If I put a disk in my CDRW WinXP fails to recognise it. However, (sometimes) if I switch off and the re-start with the disk in the drive it's o.k. Can anyone help, please?

The fat that it works sometimes but not always implies either a loose connection or a filing hardware device. When you first boot up, does the POST see the CDRW as an IDE device. If not check to ensure that you have a firm connection both ends of the connecting cable. If there are no lights showing on the CD during boot-up, also double check your power connector.

...Pretty sure it's a software problem - possibly in registry. Did not explain that the problem is on two different drives - CDRW & DVD.

Try this if the optical drives are not appearing in My Computer or Device Manager.

If nothing HAS BEEN CHANGED OR ADDED then run regedit and navigate to registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}. Highlight it and in the right pane, find the Upperfilters and Lowerfilters values. Highlight each one in turn, right click and delete them. Close regedit and restart the computer. If if doubt backup the registry first (Win98) or make a restore point in WinME and WinXP.

I had a similiar problem caused by upgrading 98se to XP,

After a clean install of XP everything worked fine

I have spent countless hours trying to solve the same problem. Both my DVD ROM and CDRW are recognised in the BIOS and in Device Manager. Windows says they are working OK. Uninstalling and allowing XP to reinstall sometimes works until I re-boot, then they may not work. The DVD ROM says "please insert a disk into drive x"; the CDRW opens a window but doesn't display any files.
I have installed a new Liteon DVD burner as the master drive and put the DVD ROM as slave. Same results.

uninstall the drives via the ide channel they sit on. ( through device manager)

...Both my CDRW and DVD drives are visible in My Computer and Device Manager. Now both refuse to register ANY disk. Have tried uninstalling them. No joy. have tried Microsoft Support. No joy there. I'm sure this must have happened to someone else. Help!

Have you recently installed software for a USB flash drive ? Sometimes the drivers conflict with those in the operating system and can cause CD drives not to be recognised. Uninstalling the flash drive software rectifies the problem.
