如果我在 TrueCrypt 容器/卷中有 15 个文件,然后假设加密卷在容器文件的某个位置损坏。这是否意味着该卷无法再解密以保留可能安全的文件?它会变得无法使用吗?
答案1
不会。TrueCrypt 块大小只有 16 字节 - 这是无法使用的最小大小。假设损坏的范围有限,您应该能够恢复大部分数据。从TrueCrypt 常见问题解答:
What will happen when a part of a TrueCrypt volume becomes corrupted?
In encrypted data, one corrupted bit usually corrupts the whole
ciphertext block in which it occurred. The ciphertext block size used
by TrueCrypt is 16 bytes (i.e., 128 bits). The mode of operation used
by TrueCrypt ensures that if data corruption occurs within a block,
the remaining blocks are not affected. See also the question 'What do
I do when the encrypted filesystem on my TrueCrypt volume is

What do I do when the encrypted filesystem on my TrueCrypt volume is corrupted?
File system within a TrueCrypt volume may become corrupted in the same
way as any normal unencrypted file system. When that happens, you can
use filesystem repair tools supplied with your operating system to fix
it. In Windows, it is the 'chkdsk' tool. TrueCrypt provides an easy
way to use this tool on a TrueCrypt volume: Right-click the mounted
volume in the main TrueCrypt window (in the drive list) and from the
context menu select 'Repair Filesystem'.
