Samsung 845DC Evo model MZ-7GE960EW health

Hello,

I am thinking about my Samsung 845DC Evo model MZ-7GE960EW health, but
Samsung software does not recognise it. Any way I can check its health
in percentage?

It might be suitable for Intel or Samsung.
There could be other, obscure designs, where
it wouldn't know how to decode the table properly.

SMART isn't exactly "standard standard". A few things
might be the same across all brands, but not everything
is that way. And wear life is one of the screwy ones.

It might be just as well to look at "Total LBA Written"
as to look at the health indicator on the upper left.
If you know the TBW rating of the drive, and the units
used for "Total LBA Written", there should be
some relationship to the life remaining.

Cheers Paul.

Health status says "good" but nothing else says "Total LBA Written"
but does mention total host writes or total host reads - current worst
values 99.

I use a little free utility called SSDLife Free. Their homepage is
https://ssd-life.com/eng/SSDLife-Freeware.html but it doesn't work for
me at the moment. I think I got my copy at the link below, but many of
the free software sites seem to have it:

https://www.techspot.com/downloads/6...life-free.html

I initially tried it out of curiosity and I kept it because the initial
display is only a health percentage, so it's really easy to see at a
glance if things are seriously wrong. There's a button to click if you
want to see all of the SMART attributes.

Thanks, the program says "healthy" - with green lettering.

While you can see the page the way it used to be, that
doesn't necessarily mean you can get a download from here.

And, I wasn't surprised at the results (binary screen dump
to my web browser). No download there.

"Samsung SSD Toolkit for Data center(2)

Samsung SSD DC Toolkit is designed to work with Samsung SSD products
including PM863, PM863a, SM863, SM863a and PM963 non-customized.
This software is not compatible with other manufacturer's SSDs.

DC Toolkit
Version 1.0 | 2.46MB DOWNLOAD === Linux

DC Toolkit User Guide
"

http://downloadcenter.samsung.com/co...Toolkit_V1.zip

It's good to see the version number doesn't change.

Inside the ZIP, there exists what could be statically
linked Linux executables.

Samsung_SSD_DC_Toolkit_V1_x32
Samsung_SSD_DC_Toolkit_V1_x64

Unzip, then

chmod 755 Samsung_SSD_DC_Toolkit_V1_x64

sudo ./Samsung_SSD_DC_Toolkit_V1_x64 --list

The utility doesn't work with my Samsung drive, but
it might work with yours. Using a hex editor, I can
see "845DC" as a text string, but that doesn't mean
anything. If the executable really understood those
drives, the model number would be sprinkled more
liberally through the executable. It isn't.

You could run that from a Linux LiveCD if you wanted.
It doesn't install. Just unpack, chmod, then run.

Looks like enterprise SSD product users are supposed to use the Samsung
Magician DC software. It can be found at:

https://www.samsung.com/semiconducto...ad/enterprise/

They separate the 32- and 64-bit downloads. The 64-bit download from
this page is:

Samsung_Magician_DC_Windows_64bit.exe @ 3.28MB

The Samsung Magician 5.1 download that I have for my Win7 x64 setup is
over 14MB in size; however, I don't remember separate downloads for th
32- and 64-bit versions, so the one installer probably has both.

There seems to be differentiation between the consumer and enterprise
software packages. Sorry, no idea what Samsung intends "DC" to mean.
The PM853T is the OEM cousin to the 845DC EVO, and both are marketed as
enterprise-grade SSDs with TLC NAND.

Health status says "good" but nothing else says "Total LBA Written"
but does mention total host writes or total host reads - current
worst values 99.

I'm using HD Sentinel Standard to monitor the health of my SSD and HDDs.
While the SMART attribute 241 "Total LBA Written" is shown, it is not
selected. Only those attributes that indicate health for an SSD are
selected when I look at which SMART attributes the HD Sentinel chooses
for my SSD. Not all SMART attributes are applicable to SSDs. The ones
the HD Sentinel uses for my SSD (Samsung 850 EVO) a

5: Reallocated Sectors Count
177: Wear Leveling Count
179: Used Reserve Block Count (Total)
183: Runtime Bad Block (Total)
187: Uncorrectable Error Count

They have a hardware compatibility page at:

https://www.hdsentinel.com/compatibility.php

Under the SSD devices, the 845DC is not listed (it appears to have been
introduced around 2014); however, that doesn't mean the drive isn't
supported. The SMART attributes very likely perform the same function
under all of them. HD Sentinel doesn't monitor every SMART attribute
that a drive reports, only those that are applicable to the type of
drive. For example, with wear leveling in SSDs, every write is remapped
to a different memory block, so how would the Total LBA Written tell you
how many times a particular memory block got written to know how often
it got stressed to reduce its longevity? More important for SSDs would
be the Reallocated Sectors Count and Used Reserve Block Count. SSDs are
overprovisioned to start with (and some tools lets you change by how
much, like Samsung Magician).

DC means data center. Data Centers don't run Windows.

The executable is a Linux executable, with no EXE file extension.

I already tested it.

It will not recognize Samsung consumer drives (I have a sample).

The executable could be tested from a Linux LiveCD terminal window.

cd /home/username/Downloads

chmod 755 Samsung_SSD_DC_Toolkit_V1_x64

sudo ./Samsung_SSD_DC_Toolkit_V1_x64 --list

DC means data center. Data Centers don't run Windows.

The do if they provide, for example, SQL Server Datacenter and their
databases. Those that run the Google Cloud Platform run the Windows
Server Datacenter editions.

The executable is a Linux executable, with no EXE file extension.

There are downloads for Windows, too, on that page and they do have .exe
for an extension.

So now I'm seeing at least five different pieces of software.
Because the label said "Samsung Magician" and not "Samsung Magician DC"
for the subsection, I mistook that for the "regular Magician".

The regular Magician is what I already have in Windows 10
(because it works with my drives).

Regular Magician == what I'd use for my consumer drives.
Up around at least version 5

Samsung_Magician_DC_Windows_32bit.exe == "version 1" (???)
Samsung_Magician_DC_Windows_64bit.exe == "version 1" (???)
Samsung_Magician_DC_Linux_32bit.zip == "version 1" (???)
Samsung_Magician_DC_Linux_64bit.zip == "version 1" (???)
Samsung_SSD_DC_Toolkit_V1 == "version 1" (contains 32b and 64b Linux cmdline)

There must be some functional overlap in the
three Linux versions. The OP can test it.

And as if that isn't enough, regular Magician is crap :-/
And that's why we'd need that many versions.

The Corsair Neutron toolbox, did Secure Erase
without wimpering. Click a button and done.
All that Magician will do, is explain to you
how the chipset is getting in its way and so on.
It doesn't do anything if you need a Secure Erase.
How did marketing decide Magician was the right name ?
Why did the Corsair Neutron toolbox work ? (I tested
both on the same machine.) I secure erased the Neutron
before returning it for a refund (so I can no longer
test it).

DC means data center. Data Centers don't run Windows.

I've been in about 500 data centers over the past 10 years and I can say
that Windows is alive and well there. Domain controllers are nearly
everywhere, running a version of Windows Server, and MS Exchange is also
extremely widespread.

The web servers and other application servers run whatever the software
vendor says they need to run. If I had to guess, I'd say that's about
65/35 Linux vs Windows. The interesting part is that 10 years ago,
virtualization was a rare novelty. These days, I'm surprised when I
*don't* see it being used.

I'm using their consumer Magician with their 850EVO SSD.

When I went to Magician 5.0, lots of settings disappeared, so only
Samsung knows what their latest version will do for those settings.
While I kept the old version's installer, I still moved to the new
version (and now have 5.1) because I wanted the newer Rapid Mode driver.

All those OS optimization settings disappeared in v5. Haven't bothered
to figure out what their software does now.

Is there anything odd about how you obtained the Samsung softwa
something other than either it came with the product, or you downloaded
it from their website by just typing in the product name/number?

I'm working round the question "If it's a Samsung product not being
recognised by Samsung software, have you asked Samsung?", by trying to
pre-think any answer (excuse) they could make.

If it _did_ come with the product, or was a fairly _obvious_ download
from the website, I would say you've nothing to lose (except hair: I
don't know what Samsung are like) by asking them.

Thanks to all,

I have not as yet booted up from a Linux live distro or asked Samsung.
I got the drive second hand and it did not come with anything else.
Will try both options.
