Hi guys,
I'm using a Samsung SSD 840 Evo for my Windows partition and want to encrypt it using the Encrypted Drive feature with Bitlocker on a 64bit Windows 8.1. This way Bitlocker should just manage the keys of the build-in encryption of the SSD and don't have to do anything itself (thereby removing any perfomance impact of a software encryption). I've tried multiple guides (the StackExchange ones for example you find immediately using Google) but so far none of them worked. Whenever I want to enable Bitlocker (I've configured it to work without a TPM btw), it only gives me the option to either encrypt all existing files or the whole drive, both of which is not using the hardware encryption of the SSD.
I've made sure that:
- I whiped my SSD using SecureErase (I've tried this already multiple times)
- the SSD has an up-to-date firmware
- Samsung Magician says Encrypted Driver is enabled
- Windows is installed in UEFI mode
I realise that there are other (and probably better) ways to do a full disk encryption (like TrueCrypt) and that I shouldn't trust proprietary software for security. For my purposes Bitlocker is secure enough. I just do not want to lose any performance due to the encryption happening in software.
Do you have any ideas what might be my problem? I'm willing to reinstall Windows (again) but only if it is promissing (no more trial and error, I've done that enough already...).
