@ukic - BIOS pass and HDD pass are two different things. If you have enabled Class 0 security option in Magician, you should see an option to set HDD pass in BIOS. If you cannot find it it is possible that this feature is not supported by your motherboard.

There are even tools that allow you to extract the password and see it.
This does not deserve to be called an encryption.


To anyone wanna know:

I send a mail to Samsung about the FW upgrade and there are no time set for that and the drive currently only support class 0 'fake' encryption.


Someone has another drive with Hardware encryption that he recommend?

Considering I have a decent and fairly new mobo, I don't see the option frown.gif

How is Class 0 encryption, fake?

Everything i see about "breaking" class 0 is on HDDs.

The ATA password you set on a Samsung SSD is encrypted by the FW and stored in the SSD's NAND, which is separately encrypted. I have yet to see anyone "break" Class 0 on Samsung SSD. Google it, you won't find anything except references to one guy who created a tool that would type in random variations of the password he couldn't fully remember, eventually it unlocked, but once again, only cuz he new part of the password. Also, unfortunately his site outlining it is gone, but if you use way back machine, you can see everything, just without images.

@Palorim12 - read the links.
tl;dr: it does encrypt the disk, but the password is saved inside the disk, which can be reset and then bypass the whole encryption. ANYONE can do this!



Edit (for your edit):
No one yet did a POC for SSD, but thats means nothing, the technology is the same.
Anyway, if you are not yet convinced, bruteforce is also VERY easy with ATA password which is not that easy with bitlocker or software encryption - or any software encryption that use hardware to encrypt (you can even use external usb key which prevent it completly).

Then please, if anyone can do it. Go ahead and crack the AES encryption on a Samsung drive and show me the results. There are threads where people have tried and were unable to. The only time i've seen it is when they know the password already or a variation of the password.

Also, the password is double encrypted. The FW encrypts the password itself, and then stores the password on a separately encrypted part of the SSD.

Palorim12 - I don't have Samsung SSD drive yet and maybe won't have at all becuase I try to find a good SSD with proper encryption.
I say it again, even if you think it not the same encryption technology, and it can't be cracked that way, it definitely can be bruteforced, and unless you have REALLY long password (which is really NOT convenient to use as ATA password and probably means your password is NOT completely random so it can be haked thru dict attack), it actually prety plausible.

Anything can be bruteforced. If you have something that is really THAT important, PUT a really long password. That's the point. You encryption is only as strong as your password. Class 0 can be secure if you have a good password.

There are no NVME drives *currently* that support the encryption options you're looking for.

Samsung's SATA SSDs do, so go for one of those.
