Stan, I was looking for a copy of the operating system for a FLuke 1722. Where I work we had 3 copies and the night shift folks tried all 3 copies before realizing it was a bad drive. These disk each offer different symptoms but are all bad I suspect. How can I get you to get me a copy of this or help me figure out how to save these disks? Any and all help would be appreciated.
