Mounting old TrueCrypt volumes

description

For securing some backups on CD/DVD I packed all files into a TrueCrypt volume (that was 2005).

Today I tried to open one of those TrueCrypt volumes using VeryCrypt, however VeryCrypt is not able to mount those volumes supplied with the correct password and in TrueCrypt mode.

I checked an old version of TrueCrypt and it was able to read the volumes.
It showed the following volume information:

Encryption algorithm: AES
Primary Key size: 256bit
Block Size 128bit
Mode of Operation: CBC
PKCS-5 PRF: HMAC-SHA1
Volume Format version: 1

Why is VeryCrypt not able to mount this image? I know that the settings are not "up to date" and I don't expect VeryCrypt to be able to create new volumes using those values, but it should be able to read them.

What is a encryption software worth if it can't read data that is some years old?

Per the documentation, VeraCrypt only support TrueCrypt volumes created using versions 6.x or higher which use volume format version 2. Your TC volumes are using pre-TrueCrypt 6.x since the volume format version = 1.

Note: Only volumes and partitions created using TrueCrypt versions 6.x and 7.x are supported.

May be it would be a good idea to add this information to the FAQ.

Additionally specifying the TrueCrypt version is IMHO correct. however which user does know what TrueCrypt version she/he used to create the volume. A concrete date would be a valuable additional information (and is easier to remember).

Therefore the FAQ could state something like this:
TrueCrypt volumes are supported if it had been created using TrueCrypt 6.0 (released Jul 2008) or higher.
