What is not guaranteed is that a tape written on a machine that is out-of-spec can be read on another machine. The tape drives gradually drift out of spec, and need periodic maintenance if you are relying on them to interchange. Sun's tape copying center cleans their drives frequently and "PM"s them periodically to make sure that they are well within specs. You can either have the drive manufacturer check and adjust it, or send one of your technicians to a class to get the test tape and learn how. Unfortunately Sun stopped shipping the manuals that the tape drive manufacturers provide with each tape drive. This means there's no way for you, the Sun customer, to find out these little tidbits. Instead you get sugar-coated manuals like the kind you get with Macintosh peripherals -- the kind that say "plug it in here, try it, call tech support if it doesn't work". In other words, the kind that assumes right off the bat that you are stupid *and* non-technical. Sometimes the man page for a device will cross-reference the manufacturer's manual, of course not giving the city, state, phone number, or order number -- that would make it too easy to be a Sun customer. But if you are persistent you can probably find the manufacturer and contact their "literature distribution" or "publications" department to get a copy. John Gilmore
