LRW: The Liskov-Rivest-Wagner tweakable narrow-block mode, a mode of operation specifically designed for disk encryption. Superseded by the more secure XTS mode due to security concerns. [122] XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption.
VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [5] The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition [ 6 ] or (in Windows ) the entire storage device with pre-boot authentication .
Portable or "traveller mode" means the encryption software can be run without installation to the system hard drive. In this mode, the software typically installs a temporary driver from the portable media. Since it is installing a driver (albeit temporarily), administrative privileges are still required.
TrueCrypt is a discontinued source-available freeware utility used for on-the-fly encryption (OTFE). It can create a virtual encrypted disk within a file, encrypt a partition, or encrypt the whole storage device (pre-boot authentication).

(Note that this is not the same leak the ECB mode has: with LRW mode equal plaintexts in different positions are encrypted to different ciphertexts.) Some security concerns exist with LRW, and this mode of operation has now been replaced by XTS. LRW is employed by BestCrypt and supported as an option for dm-crypt and FreeOTFE disk encryption ...

For Data at Rest protection a computer or laptop is simply powered off. The disk now self-protects all the data on it. The data is safe because all of it, even the OS, is now encrypted, with a secure mode of AES, and locked from reading and writing. The drive requires an authentication code which can be as strong as 32 bytes (2^256) to unlock.
