Christo Design Further Diagnostic Questions and Some Fix Suggestions 6. If the CD/DVD Drive Does Not Read Disc Properly: • Try restarting your PC before checking or doing anything. • Make sure your CD or DVD has the data side down and the label up. • Can the disc that you are trying to read, be read from another computer? Is your disc suitable to your drive, for instance are you trying to read a DVD in a CD only drive? The issue might be a disc one. • Update your player software. • Update your BIOS. • Update Windows completely. • Look for an issue on your CD/DVD drive's website. There may have developed a new issue with your drive after Windows installed an update. • Update the firmware for your drive from your computer's manufacture site or the drive manufacturer. • Do you get an "Incorrect Function" error when you insert a disc ? This problem is caused by Roxio Easy CD Creator 4.X or earlier which is incompatible with Windows XP. See the Microsoft article here. If you have Easy CD Creator 3.X or 4.X, you must upgrade to at least 5.X or 6.X Easy CD Creator. If you have these versions and you get the message, you must install the Microsoft XP update for Easy CD Creators 5.X and 6.X that is available at Roxio's site here. • You might also make sure the drive is on Windows Compatible Products List. • You might also look at the registry settings at these two locations and delete the “No Drives" values if they exist and then restart your PC: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Policies\Explorer and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ policies\Explorer. I'm not sure if this would enable a CD/DVD drive to read a CD/DVD that it initially could not. • Locate the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\CD Burning\Drives\Volume{GUID} Check the value of “Drive Type”, if it is equal to DWORD = 1 is a CDR, DWORD = 2 is a CDRW, DWORD = 3 is a CDROM. Adjust this and reboot the computer. • Additionally you might look at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ policies\Explorer Modify/Create the Value Name [NoCDBurning] according to the Value Data listed below. Data Type: REG_DWORD [DWORD Value] // Value Name: NoCDBurning Value Data: 0 [0 = Enable Burning / 1 = Disable Burning] • Uninstall your CD/DVD drive and then have Windows rediscover the device through the add hardware wizard (by right clicking on the root of your computer in Device Manager and choosing "scan for hardware changes.") See here for an explanation how to do this, see method 2 from here. • Uninstall and reinstall the secondary IDE port. See the article here. • Does the CPU high usage while accessing or recording? This problem may caused by the drive being not enabling the DMA transfer mode. Right click in Device Manager on the Advanced Settings Tab on the secondary IDE channel. Change the drive from PIO to "DMA when possible" access. This script when executed (ignore the warnings) will set all the drives back from PIO mode to DMA. Perhaps this will solve your problem: You can also try to do the reverse and set DMA to PIO only and see if this allows reading of a disc . • Make sure that your CD/DVD drive is on a separate IDE cable than the one you are using for your hard disc (s). Usually hard disc are on IDE or SATA channel 1 and the CD ROMs are on channel 2. Mixing the two kind of drives sometimes causes them to malfunction. • Try the XP-DVD Fix program. • Install the Microsoft Autoplay Repair Wizard. Amazingly this apparently fixes some drive reading problems. • Remove the upper and lower filters from the registry key at: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class/ • 4D36E965-E325-11CE-BFC1-08002BE10318. Removing these registry setting may restore the player’s ability to read however it may also stop its ability to burn CDs and DVDs from working. You may have to reinstall burning software. See here for a description how to do this with your registry. You should especially remove the filters if CD-ROM access is missing and messages cite error Code 31, Code 32, Code 19, or Code 39 after you remove Easy CD Creator in Windows XP see here for Microsoft article on the subject. See this article on removing additional filters. • If Sony’s Rootkit was ever installed, try using the removal tool from Sony to uninstall it. This may have happened and you not known about it. See the link. • Try the sfc /scannow command. Sfc /scannow command scans all protected system files immediately and replaces incorrect versions with correct Microsoft versions. This command may require access to the Windows installation source files. Click Start->Run and type in sfc /scannow, then press OK. Note: there's a blank space between sfc and /scannow. • Do you get an "Incorrect Function" error when you insert a disc ? This problem is caused by Roxio Easy CD Creator 4.X or earlier which is incompatible with Windows XP. See the Microsoft article here.
