Yeah - maybe a few of them work. DUDE. But, if he changes to Taiyo Yuden or Verbatims, and assuming the drive is OK, almost all of them will work. It's the difference between a hit and miss approach and peace of mind that a burn will work.
We go thru this every now and then with nebies and wannabees. The number 1 rule here is USE GOOD MEDIA..
Now, stop arguing and get with the program. I can see that you wanna help. But trying to help a guy by ignoring the primary issue is not helping at all.
