I’ve been using a DRU-710A (Lite-On 1633s), currently with firmware rev. BYX4 for nearly 8 months with no problems. It has performed flawlessly until yesterday, when it would not recognize a DVD+R disc. I’ve been using Verbatim DVD+R 8x discs for a while now with no problems. Nero tool kit shows that this drive recognizes CD-ROM, CD-R, CD-RW, DVD-ROM, DVD±RW, DVD movies, Audio CD’s, but not the DVD+R blank media I’m using. I’ve tried everything I can think of to correct the problem. I’ve removed the drive, both physically and through device mngr. with no success. I’ve removed the IDE ATA/ATAPI controllers and rebooted the machine with no success. I considered reflashing the drive to an earlier firmware rev., the reflashing back to the current rev., but was afraid of permantly disabling the drive. Has anyone else had a similar problem and found a way to correct it?
