Protecting systems with the TPM

The real advantage of the SEED devices is that if one breaks, you can ship it back for repair without worrying about someone being able to read you put on the drive. The inept key management is unlikely to leak the key back to the drive manufacturer, but one never knows if the SEED keeps a copy of the decryption key. Certainly, three-letter-agencies which can replace disk firmware, are capable of such an attack.
