They all come from the same bin. Those that can't hack the required performance of a denser media are certified as SD. I wouldn't suggest punching extra holes in the diskette to use the second side for reasons cited in another reply (emjhm@uokvax). If you choose to use diskettes that the manufacturer will back up, you want SSDD and 96 TPI. Certain manufacturers claim to certify the entire surface of their media, in which case the 96 TPI clause could be ignored. Other SSDD media will only be certified for 40 or 48 TPI operation, so you take your chances. There may be bad areas between tracks that your rainbow will attempt to use. I have heard that there is public domain software that will check a diskette for bad sectors and set up a list for the operating system so as to avoid using these areas, but I have no detailed info on that. Hope you enjoy your Rainbow. Good Luck!
