Hello everyone One of my friends has this Samsung drive SH-M522C. Its again a CDRW/DVD Combo Drive. I noticed that the drive had only 1.5MB of Buffer memory (this is unusual because the Samsung website states that the buffer memory should be 2MB for this drive). It wasn't reading a few of my CDs properly, and I was not even able to change the region code for DVDs on this drive (It is set to 1 and my region is 5). So, is this a shady drive or what?
