I have 2 optical SATA drives installed both made by Asus (one is DVD the other is DVDRW). They worked just fine for about 6 months then one day the computer refused to boot and the drives were not detected in BIOS. I opened the case and tried reseating the connectors. The drives showed up in BIOS again and were detected on boot up but when I get into windows the drives are not showing up in my computer and even auto-run CDs won't run. I tried brand new SATA cables and those did not work either but I do not think it is the cables because the drives were detected on boot up and the drives still didn't show up in that instance.
I tried the solutions on the windows knowledge base about resetting/deleting upperfilters and lowerfilters and this did not affect the problem. In device manager the drives simply do not show up. I tried resetting the registry settings for the drives and rebooting but that didn't work either. The drive power light goes on when you put a CD in but it doesn't play even as an autorun. Also have an 850w PSU and adequate cooling so not an issue with powering the drives consistently or overheating. Tried blowing the case out with compressed air just for the hell of it but no dice. All the cables are plugged in tight.
Model Numbers: DVD-2616A3T and DRW-2014L1T both by Asus
