I'm starting to see a trend with some brands of floppies more than 25 years old where the oxide is starting to separate from the substrate, leading to fouled heads and "see through" tracks. Mostly on Wabash brand floppies currently, although a few off-brands such as "Precision" seem to also be showing this behavior. Time to get 'em archived. Cheers, Chuck ________________________________ -----REPLY----- Agree. I have made disk images of about 400 NorthStar Horizon disks. I am seeing some percentage of disks which just are not readable any longer. Fortunately, not too many but it seems like INSUA and other original disks are the worst. What I am doing and encourage others to as well is to make disk images of all of your NorthStar Horizon disks. Write a one line summary of the contents of the disk into an index and send the images to Bitsavers.org. There is a NorthStar Horizon disk image archive at: http://bitsavers.org/bits/NorthStar/NorthStar_Horizon/ You can send the disk images and indexes to me and I will load them for you. Don't let your NorthStar Horizon information fade away. Once it is gone, it is gone for good. Thanks! Andrew Lynch
