As things stand, there is no news blackout, just careful work being done - the preliminary Dutch findings are due in a couple of weeks. Of course, that doesn't suit Russia, they were peeing on the results by saying a decent read could have produced a resulty in under three days. That presumes two things: firstly, that there's no need to interpret the results, that raw data is all that's needed, and secondly, that the data was trustworthy in the first place. Given that it had been in the hands of the people suspected of causing the problem in the first place, they almost certainly had to read not just the top write, but the layers under that, to prove the data was contiguous. If it wasn't, then the layers below had to be read, and that takes time.
When you write data to any magnetic record, you leave a field which the next reader can follow. But when you write over it, even erasing it, you don't get rid of it perfectly, you leave sidebands which the data can be reread from. Remove the top signal, you get a weak layer on top - the previous write is still readable, if done slowly and carefully. The third, even harder - but doable. That, I think, is what took the time, the careful check and recheck, and then the interpretation. The full report won't be there until 2017, and that's scientists for you, dotting the "i"s long after the boat has sailed.
What that report says, I have absolutely no idea of. But don't jump the gun just because you have an agenda.
