I bought a couple of the HP 8X+R 25-disc packs last month at Office Max, and they were CMC MAG E01-000. Nice purple and white labels (don't remember how they were sealed), but while I can burn lots of stuff at 8X with my Zebra mod 411s/811s, I have to burn these ones at 2.4X (even though they show as 8X in all identifier programs). Anything faster produces loads of unreadable sectors. Finally returned the unopened one and used up the others when I had plenty of time to burn.
I found a ton of "Made in Japan" Fuji 8X +R in the 50-packs at Best Buy this week, for $20.00 each. All turned out to be TY (YUDEN000-T02-000). That same SKU number was showing as on sale for that price at their website, but since they showed there as being 2.4X, I wasn't gonna take a chance on them. Got a chance to get to the store, and got lucky.
