Ah, okay. The notes I jotted down from MacIver's talk at HITB in
Malaysia indicate he said it was on by default in the upper versions,
but I could well have written it down incorrectly. Thanks for the
correction.

Just a nit:  as I understand things, Bitlocker is available, but not
on, by default.  Someone needs to actively flip a switch to make it
go.

Well for one thing, any software based FDE is extremely slow, doubles
the file access times, and is a serious drain on the laptop battery.
See the URL below for a software based FDE benchmark/analysis:

What if the encryption key for the Seagate's HDD can be managed using
TPM, i.e. wrapped, bound and stored on the TPM. The user will just
have to authenticate to the TPM, using a Token or a static password,
then the FDE encryption key will be available to the HDD Will this
solve the problem?
