Re: Actual case aside
If there is (accurate) information about the use pattern then the claim "chose not to" might be reasonable, e.g. if the system log shows the drive being mounted three times a day for the past year then a claim to have forgotten the password a few days later may strain credulity.
However it certainly wouldn't be reasonable for a fallow device - I have a PGP disk volume from many years ago which proved not to have any of the passwords that I remember using then and resisted brute forcing. I've hung onto it out of sheer cussedness - probably whatever is inside is now devoid of real interest but, damnit, I want to know! so I still wait for some long-inactive neuron to fire and spill the beans...
