Howdy. I have 50 of those multicolored CD's. I burn them in my CD-RW drive and test them in my DVD+RW before I delete stuff off my HD (I make monthly backups). I've used all the colors (red, blue, purple, orange, and black), but, the black ones don't seem to read in my DVD+RW drive. Does anyone else have this problem (or have heard of it)? The other color disks work fine in my DVD drive.
