Yeah, analog stuff is sorely lacking, as if RF stuff today. My only comment about data resurrection is that I'll bet that good analog data from the disk varies with the density. Getting data off an 800M to couple G disk? Absolutely. But I wonder far more about a 1T disk. I'm not saying it can't be done; logic says that disks of the modern era should still be destroyed, but I'd love to know how much data gets garbled when sniffing really high density disks. --STeve Andre'
