面白そうなネタだがこの辺はどうかな Q: Is it possible to mount a TrueCrypt container that is stored on a CD or DVD? A: Yes. However, if you need to mount a TrueCrypt volume that is stored on a read-only medium (such as a CD or DVD) under Windows 2000, the file system within the TrueCrypt volume must be FAT (Windows 2000 cannot mount an NTFS file system on read-only media).
Q: How do I burn a TrueCrypt container larger than 2 GB onto a DVD? A: The DVD burning software you use should allow you to select the format of the DVD. If it does, select the UDF format (ISO format does not support files larger than 2 GB).
