supported on SSDs. This limitation is due to a significant number of rotating media drives not
correctly supporting the SATA Secure Erase function, which results in hard drives that are
completely unusable.
Encryption (Menu 3)
The TD2u can encrypt destinations using whole disk encryption. All data stored on the
destination is encrypted and hosts will only read seemingly random data until it is decrypted.
Decrypting the data requires special decryption software/hardware and knowledge of the
password used for encryption. On Windows, the publicly available open source program,
VeraCrypt, can read disks encrypted by TD2u. However, drives encrypted first by VeraCrypt
likely cannot be used by TD2u without re-encryption.
See the Guidance Software website for more information about whole disk encryption used by
TD2u, including details about the exact algorithms used and the security of drives encrypted
this way.
Encrypt New Destination (Menu 3.1)
This operation allows you to set up new encrypted destinations. Whole disk encryption
requires this setup, which writes over any data on the drive to create an encryption container
for whole disk encryption. Only drives encrypted this way are supported as encrypted drives
by TD2u. The TD2u identifies drives that appear to have been encrypted this way.
