XEX-based Tweaked-codebook mode with Ciphertext Stealing
XTS is a block cipher mode designed specifically for encrypting storage, where each disk sector must be encrypted independently and there is no room for authentication tags. AES-XTS is what BitLocker, FileVault, LUKS, and self-encrypting drives use for full-disk encryption. It hides patterns across sectors but, by design, does not detect tampering.
