Three weeks ago i had a NEC 1300a that i had for 2 years with no problems, but then in its final few weeks the DVD+R disks i would burn would on usual occasions get a Scratch or sometimes two coming from the outside edge of the DVD+R disk inwards. They were Ritek disks and looked perfect before burning. I bought a batch of 500 (5 x 100), no probs with 200 of them then this one batch problems, i opened another batch of 100 and still the same problems. I believe i also tried a few Verbatim +R’s with the same scratches problem.
PC world reluctantly swapped this drive for a Sony 720a DVD drive they said in there opinion it was not the drive that was faulty and i would get the same problems if they replaced drives, but they reluctantly did replace it. But like they said i have started having the same problems with this new Sony drive too, DVD+R’s at edge getting scratches of varying length going inwards. (it doesnt seem to be happening with DVD-rs for some reason, or at least it hasnt yet)
Like i say the Disks look perfect before burning and they are Riteks. But for it to happen on two drives is unlikely. What is causing this and how do i fix it. I have my computer on a proper computer stand, (as PC world said it could be caused by vibrations due to use of a poor computer stand). And am using windows XP.
