Problem with Verbatim media
I have been having lots of problems with Verbatim DVD-R #95102. This product has an excellent reputation, and I had been using it without problems for a long time. Several months ago, I started noticing lots of disks with obvious visible defects and some that my computer wouldn't recognize. Just about every disk I insert will start spinning at high speed for perhaps a minute. In some cases, the burn will start. In other cases, it will eventually be rejected. I tried a SuperDrive from another MacPro and got the same results. So it seems that the Mac suddenly doesn't like Verbatim. It works fine with other media. The Verbatims work fine in a DVD duplicator. So it doesn't appear that they are defective (other than the ones that have visible defects). Anyone else having these problems? Is there another brand that is more reliable and also has a reputation for high quality?
