Samsung EVO 850 crash...

    That is incorrect and everyone should understand, this is hardware based encryption and no action required from the end user...
    Sorry, but you are incorrect. FDE is NOT enabled by default on these drives. I have 850 EVOs and 850 Pros on this and other systems here. It is supported by these drive, but it must be enabled manually.

    See the Samsung White Paper, Protect Your Privacy, Security & Encryption Basics.

    TL;DR: Apologies, but you do not fully understand how FDE works...

    Quote from your referenced link:

    Enabling AES Encryption

    AES encryption is always active on an 840 or 840 Pro Series SSD*. In order to benefit from the encryption feature, however, the user must enable an ATA password to limit access to the data. Failure to do so will render AES-encryption ineffective – akin to having a safe but leaving the door wide open. To set an ATA password, simply access the BIOS, navigate to the “Security” menu, enable “Password on boot” and set an “HDD Password.”
    *-Emphasis mine...

    Question...

    Which part of "AES encryption is always active on an 840 or 840 Pro Series SSD" you disagree with? And yes, the same applies to the 850 or 850 Pro Series SSD as well. For that matter, to any other FDE drive that supports TCG Opal 2.0 specifications.

    Your link clearly states that:

    In order to benefit from the encryption feature, however, the user must enable an ATA password to limit access to the data. Failure to do so will render AES-encryption ineffective – akin to having a safe but leaving the door wide open.
    In another word, without controlling access to the encryption key, "Everyone" has access to the data, despite the fact that it is encrypted internally in the drive. It's pretty much what I've stated earlier in this thread.

    Quote from Samsung:

    Secure Data Through Advanced AES 256 Encryption
    The 850 EVO comes fortified with the latest hardware-based full disk encryption engine. The AES 256-bit hardware encryption secures data without any performance degradation and complies with TCG Opal 2.0. Easily integrate into Windows with Microsoft e-drive IEEE1667 to keep your data protected at all times.
    Weather you know it or not, your 850 series SSDs from Samsung do encrypt the data internally on the drives. You did not need to enable that since the encryption is active within the drive by default. What you would need to enable is the BIOS password in order to prevent anyone else accessing the drive. That would secure the data from unauthorized access, but you did not take that step.

    I do understand how it works but it seems you don't understand that it is NOT enabled by default. From my link and your quote,

    In order to benefit from the encryption feature, however, the user must enable an ATA password to limit access to the data.
    *-Emphasis mine...

    Active is not the same thing as enabled. The light switch on my wall is "active" but the light overhead is not "enabled" until I, the user, flip the switch.

    You are suggesting by default users of these SSDs cannot pull the drives and put them in or attach them to another computer and read the data. That is simply false.

    Yes, it is always on and enabled by default...

    I've never suggested that, read my posts on the matter...

    I give up, you just can't comprehend how TCG Opal 2.0 specification based FDEs operate...

    Windows 8.1 Update 1 64bit Pro


    just a note from me.

    Do "not" use the "os optimization" feature in samsung magician, it makes changes that are considered bad practice.
    Installing samsung magician will not affect your system on its own unless you utilise that optimization feature or enable the rapid mode (which I would also keep off).

    Magician has the following useful functions.

    1 - manual trim. (performance optimization)
    2 - over provisioning setting
    3 - secure erase
    4 - viewing drive stats, bytes written and SMART data
    5 - benchmark tool with historical data
    6 - firmware update, although I wouldnt ever update firmware if existing works fine.
