I received unopened discs. These discs are new from old stock meaning they may have sat on a shelf in a warehouse for 20 years or more so over time they may have lost their track and sector magnetism. This can be fixed by low-level formatting in DOS (FORMAT A: /U). This will write new tracks and sectors and make the discs usable again. I used to order a pack of 50 and they were in Macintosh format. They can also be reformatted into PC format under DOS.
