When using TrueCrypt, you have to declare a size for the file upon creation of a new volume. What happens if the files encrypted in that volume grow to exceed the declared size?
Example of editing a file: A volume is created with a size of 1MB. Initially, there is a 1kb text file in it. Then, I edit it and add enough data that the file now exceeds 1MB. What happens when the file is saved and the TrueCrypt volume is dismounted?
Example of adding a file: A volume is created with a size of 1MB. Initially, there is nothing in it. I mount the volume, add a file that's too big (say, a 2MB mp3 file). What happens when the volume is dismounted?
Will there be a warning message? Will the data be silently dropped?
