Early Earth/Starfleet probes.

I have recently been thinking about some nitpicks I have with the 22nd Century Quadros 1 probe (I'll come to the Friendship One probe later...). How did its data get back to Earth/Starfleet/UESPA? When Sisko and Dax exit the Bajoran wormhole for the first time, the Computer instantly knows that this system is Idran, as discovered by the Q1 probe. Also, how did a probe from the 22nd Century get to almost the opposite end of the galaxy and presumably back again? It would have to be an automated Starship at least to carry enough fuel. With no crew spaces or life support, you would have extra anti-matter space. Matter could be collected by the Bussard collectors, but anti-matter generators haven't been mentioned until the Galaxy class era. The speed it could travel at though could be up to about Warp seven, which at the time is 7^3 which is 343c which according to this page http://home.att.net/~srschmitt/script_warpcalc.html would take 262 years to reach that destination. To get there and back, warp 10 (1000c) would be required. This speed with that technology with only automated maintenance? Highly unlikely I say. Also, travelling 90,000 light years, with the Galaxy being a dangerous place, surely the probe would have been destroyed or commandeered long before then?
