We recently (two months back) bought a Samsung DVD-RW drive (TS-H552U), the drive worked properly with all CD-R and CD-RW models, but when trying to use it against moser baer products it just doesn’t recognize the disc. Since we also had another DVD-RW on a laptop (Fijutsu) we were able to test the disc and it happened to work just fine.
After some one month of running to and fro from the Samsung after sales support centre, they have agreed that they aren’t able to resolve the problem and are willing to reimburse the original amount (We even tried with a new replacement drive).
Just thought of putting it so it maybe helpful to any new deciding party.
