. . . which is subsequently rendered useless by the TPM erasing itself.
(The standard procedure is to encrypt the drive using a key stored in the TPM. The TPM then decrypts the drive when provided with the proper authentication. If the designated security policy is violated the TPM destroys the key, rendering the drive's contents useless.)

- yew 15y agoThey are intended to be tamperproof, yes. Mirroring the contents of a TPM is an exercise in hardware deconstruction where you also have to worry about setting of auto-erase traps. It's not impossible by any means, but it's not standard procedure and there's no guarantee it will actually work.
