You are not in good company in your position here, which doesn't say much, but it nonetheless is the case here. Fact remains if the intent was to retrieve the emails after the drive crashed, that the emails would have been retrieved. If the intent was to destroy the emails intentionally and destroy the ability to retrieve them, then you would fail to use back up tapes, fail to recover a drive with bad sectors (straight forward), and fail to properly report the whole thing to national archives and records. You might even do this with a monster IT budget of 4.4billion dollar budget over the past 4-5 years while crying about budget excuses for the inability to recover the drive.
