The drive no longer recognizes CD's at all. It says insert disc when a disc is inserted. The only discs it recognizes are DVD's. I found a website http://www.css.ap.sony.com/consumer...=35943&Category=Optical+Storage&Model=CRX320A that will allow you to update the firmware in the drive. I updated the firmware and it still will not recognize cd's. Is this drive dead? Does it need new drivers? I cannot find new drivers for it anywhere. Any suggestions would be helpfull.
Same problem here. Occured after installing Nero. Once I have repaired it by System Restore, but it has occured again, and nothing helps. I updated firmware, changed DMA settings, reinstalled fresh versions of Win XP 32, Win xp 64 on different partitions. I have AMD 64 bit Athlon on Asus A8V Deluxe motherboard. Another guy with same mother and proc. has had the same problem, but no solution http://64.233.183.104/search?q=cach...ve+two+lasers&hl=en&ct=clnk&cd=1&client=opera He even purchased a new Combo drive, only to find the same problem.
You could try the Upper and Lower filters trick: It is a Windows thing, losing drives when installing/un-installing burning software… If the drives are still listed in the Device Manager, delete them then carefully follow this fix: "Upper/Lower Filters: a. Click on Start --> Run --> and type in 'regedit' followed by the enter key b. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or clicking the "+" next to it.) c. Expand the "SYSTEM" Key d. Expand the "CurrentControlSet" Key e. Expand the "Control" Key f. Expand the "Class" Key g. Look for a key containing the following string of letter and numbers: {4D36E965-E325-11CE-BFC1-08002BE10318} h. Highlight this key by left clicking once on it i. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these delete them by right clicking on them and choosing "delete" j. Exit the registry by clicking on the "X" in the top right hand corner of the screen Reboot your computer"
GrandpaBW and all here is a upper and lower filters utility Here's a useful free utility for anyone interested...devFilter from busTrace.com http://www.bustrace.com/products/devfilter.htm Introduction busTRACE Technologies has developed a simple utility that allows you to view which filter drivers are specified for the Disk and CD/DVD devices on your computer. This applet shows you those filter drivers that are specified in your registry. They may, or may not, be actually running. That is dependent on the driver itself. This is a useful diagnostic applet for those users who have a need to determine which Disk/CD/DVD filter drivers various 3rd party applications, or Microsoft itself, have installed on your system. You can download this utility for free. What operating systems are supported? The software only supports Windows 2000/XP/2003 and above.
