What happened to the disk that Haibara lied about in the episode 177 (Re-union with black organisation)

Haibara said it was burned down, but she was lying, is this disk important? and what was actually in the disk?

[MeiTanteixX]

All necessary data to make apotoxin, probably...nothing is completely confirmed when it comes to how much info is stored in it...

[Balthazar Manfredie]

it will appear on a Hard disc now, if appears again 

[Chekhov MacGuffin]

The last disk Haibara accidentally mailed Akemi (which was erased by the Night baron virus) had real names, addresses, and codenames of agents, and the name of the person/people who invested money for the research that were in with the drug data. I think it is likely the disk Haibara is lying about probably also contains this information.

Oh wow that's so far back that I've completely forgotten about it but good question. I'm curious just what is on it and why the heck she's keeping it from Conan if they're on the same side unless it really was messed up. Hard to say at this point but I'd likely to think if it is still working she'll bring it to light again soon.
