Unifino -R

I got my 2500A a few days ago, along with a ten pack of 10 Unifino 4x -R disk. To be honest, I bought them because they look nice on the top and I have heard that Japanese media is considered the best. All ten burned fine with CopyToDVD @ 4x (I think). What can I do to check the quality of burns? They play and look great in my Panasonic DVD player.

Thanks, I know know i’m a total gumshoe :iagree:

If you have no other drives for media testing, just use the 2500. Get CDSpeed-3 and run the scandisc test as well as a transfer rate test. If both are normal, then don’t sweat it.

If you have a DVD-ROM, use that for testing, it will read the disc a bit faster and provide a more “strenuous” test.

Hi again, I got a 50 pack of the Unifino -R today and the disk are taking twice as long to burn…up to ~30-33 minutes. Before they only took about 16 minutes. They are suppose to be the same disk, what could have happened?

Thanks

Please post the media code on the new stuff as well as the old stuff.

Those are indeed the same identical discs.
