Hi all, A week ago, I used TrueCrypt 7.1a to create a hidden volume inside an outer volume. Everything worked well. But today when I tried to mount the hidden volume, it said “Incorrect password or not a TrueCrypt volume”. I am sure the password is correct. In the meantime, I tried mounting the outer volume. And it worked well. I tried to restore the volume header. When I put in the password for the outer volume, it successfully restored the volume header. But when I put in the password for the hidden volume, it still says “Incorrect password or not a TrueCrypt volume”. I am quite certain I remember the password correctly for the hidden volume. What seems to be the problem? And how can I solve it? Please help!
