Bud, Felch, Jad - all other purchasers - are you giving these burned-disks to pals for their use and, if so, are they reporting any Read problems?
I've sent data-backup disks to 8 different users in these last few months without any issues being reported. Of course, we know that the 2-3 year life-cycle can be more telling. My Sends are relatively unimportant and the recipients copied the disks' contents to their hard-drives, so they may not re-access these disks ever.
The bargain price on these certainly qualify them as 'low end/high risk' but so far, so good. No coasters and we're on Batch #3 using Pioneer 207s and 208s.
