i have a tdk dvdrw1280b, when first purchased it worked great, after a few months the burner started to clunk out on me, wouldnt burn right, come to find out it was the dvdr's i had just purchased, before that though i tried to upgrade my firmware, i know i have the correct firmware, t7s4 is the firmware for it, since installing though it will play cd's and dvd movies but anything that is on a dvdr im ****ed, all my data is backed up on them as iso's and so i cant even get access to files that may help
