It won’t read, or even recognize, DVDs I have burned on it. I have tried different brands of DVDs (Verbatim, Smartbuy… all DVD-R), the burn process completes successfully, it verifies the written data, but when I reinsert the DVD, it is not recognized (drive not found). However, I also burned a DVD-RW, just to check, and everything was OK, the disc is reading with no problems! I also gave one of the DVDs I burned to a friend, and it worked fine on his computer, read fine, no problems whatsoever!!!
I have recently reinstalled my OS (XP professional sp2) and updated it over the internet, but I had exactly the same OS before (with no updates from the internet), and my AD-7170A worked fine!
I really have no idea what is wrong. Please help me!!! Thanks
