Assume one day you receive the following error from TrueCrypt:
is that a reason to worry that someone may have removed the disk (in my case disk 0) and used it offline and then put it back into the laptop or am I too paranoid?
Note: the above option fixed it, but the question is what would disable the automatic mounting in the first place. Especially since we're talking about the boot drive here.
Also note: I am using Intel Matrix RAID to cache the boot drive, in case that changes something.
