XP Does not recognise my CDR drive or CD discs?
This is a well known problem with XP, if you cannot access CDROM, DVD, CDR or CDRW drives or get a Code 31 or 39 error in Device Manager then the solution is to run Regedit and delete Upperfilters and LowerFilters using this program xp_cd_dvd_fix.vbs and then restart the PC. See Q2700008 and Q324129 on Microsoft’s Knowledge Base. Old versions of CD Burner software should not be used with XP such as Easy CD 4 or old versions of Nero (lower than 5.5), check websites for updates first. A list of compatible drives is available from Nero or Easy CD. If you have recorded a CD in XP and becomes unreadable or files are missing then download a CD Burner update from Windows Update Site or from Program’s Manufacturer’s web site (EasyCD, Nero, Winoncd etc). If you are having problems reading packet written CDRW discs, download a UDF Reader program.
