I posted this in another thread.... But here goes.
Ok so basically to get these you need to get in an SRV and go to settlements.
Once at the settlement you will want to find "data points". You target and scan the data point.
Once you scan the data point it will begin a timer. You have x seconds to find the next data point and scan it before the timer runs out
Each data point scanned adds time to the timer
Once you scan all the data points (order doesn't seem to matter) you get 1-4 "data" materials.
Certain settlements are dangerous. The ones that drop MEF will be dangerous to go to. However below is a list of ones you can go to in order to have a reasonable chance of MEF's without being in danger.
***Just don't enter the "red zone" on your scanner or you get a fine and the enemies come after you.
So below is the list of settlements you will want to go to. I modified the list from the original poster so that you can go in order. Instead of jumping from 100 ly back then abck again I tried my best to make it a line you follow so your not back tracking and wasting time flying from one end of the bubble to the other. Its not perfect as I was eyeballing it when I made the list.
1. Go to the settlement
2. Go to

Look for the "type colum" and next to that see if the maps colum has a path link. Then compare the settlement type I have listed for that settlement with the type on the site and use that map. Its always the same map for that type. The path is the recommended one but you can use another path. I prefer having the map open on my 2nd monitor while doing it.

I got 50 MEF about half way down this list.
Also you if you dont scan all the data points in time just restart.
Once you do complete the scan of the 3-5 data points you can't rescan them again until around 2 weeks or so has gone by.
And my personal recommendation...don't worry about damage as your running aroundin your SRV. When you dock with your ship again you will repair the SRV fully. So unless you go really crazy dont worry about being too careful....just go fast
Fuel is the only thing you need to worry about but honestly just jump out, do the data points, jump abck in your ship, go to the next settlement and you wont ahve to worry about that either....if you have sulpher and phosphporus thingy you can use that otherwise just go ahead and dock at a station which auto refuled your SRV.
