I have a similar problem to the one mentioned in the post of zombie_dimaggio "DVD drive won't work now..." (http://forum.slysoft.com/showthread.php?t=2488). My dvd writer stopped working. Recorded "succesfully" (when I checked afterwards -nothing was recorded) one dvd (had recorded with clonecd and clonedvd about a hundred copies before) and in the middle of the second one stopped -couldn't see blank dvd media any more. The dvd writer is seen in hardware profile as "working properly". Cannot recognise or play neither blank or written cds/dvds. The only things that changed (one day before) was moving my pc from one room to another (change of power supply plague) and expiration of Norton Internet Security. My system is Win Xp Pro SP1 (cannot install SP2 now, since I cannot use the writer). I run CloneDvd, CloneCd, AnyCd, Sony Vegas 6 and all Sony Media Components (Media Manager, Director, Sound Forge and so on), DvdDecrypter (never use it though). I had before Roxio EMC and Nero, but uninstalled both plus used their "cleaning" programs because of many problems they created (compatibility issues I guess). I already did the following: -upgraded firmware for my dvd writer (cannot find newer driver as my dvd writer is mentioned in system as DVD RW IDE 16x. After long researched I understood the manufacturer must be BTC branded (cheap stuff that came with my pc) and its driver as listed is cdrom.inf (from Windows drivers database, was unable to find any other or newer one + nothing on BTC site) -took pc to "the last configuartion that work" or whatever they called it -used system restore (didn't work, took it back to today) -removed other drivers associated with dvd writer -there was anydvd driver (when removed the writer dissapeared completely, even from hardware list), some redbook driver, and three others also associated with Slysoft software. Had to unintsall and reinstall anyDvd in order to see the drive again -removed upper and lower filters from registry -uninstalled Sony software and since there was no change -reinstalled -checked DMA mode (is on 2) -made sure writer is on Secondary IDE Channel as master, and hard disc with Windows on Primary (have a second hard disc connected, doesn't seem to appear anywhere, only in hardware list) -checked drive letter (D: ) and made sure enable writing to cd in options is checked -made sure all Slysoft software and DvdDecrypter are on permit list in Norton Internet Security -When I cleaned remains of Roxio instalation from pc with RoxiZap I could still see some Roxio stuff in the registry, so went and removed everything with Roxio in the name from there. Maybe it was a huge mistake? I know I'm not supposed to do it, if I don't know what exactly I do. If it plays any role -I recently installed Windows ON the old one (hence why don't have SP2), because of other problems with system files I had. The problem was not fixed, still got the missing system file error when loading Windows, no file specified, just "/system". I didn't have time to reinstall some drivers that I thought were missing after the Windows installation (I noticed most were still there), but what COULD be missing were external graphic card (still have one onboard), motherboard drivers that came with pc, audio, Sony digital camera I use on firewire, webcam... I am not sure what else. But I think most were still there. I really don't know what else to do. I cannot access BIOS either, for a long time now (since I installed Windows fresh few months ago on different langauge version). I don't know anyway what I could do there. Change IDE connections? I hope my explenations are not too vague, I'm a complete ammateur, most times follow instryctions from forum, I hope I didn't make tooo much mess trying to fix the problem. I am sorry my system description is not clear and complete -I'm writing from work, and am not able to check all info now. Thank you for your patience in reading such a long post. I will appreciate any help, please!
