update: only size incorrect issue remain

for some reason wrong size is shown for the drive 880GB instead of 960GB

i am running with ubunu 20.04 live cd.

i successfully formatted and erased using hdparm









i tired format with Samsung DC toolkit but it fails:

here is some reports\logs:

Sorry there was never a firmware update as far i know, only DXV8C03Q existed, and you cannot download the firmware from one drive and upload it to another.
Are you sure that there is no HPA (host protected area --> setmax) enabled?
I use HPA for overprovisioning SATA SSD's.

Probably one of the best 3D-NAND ever made: the 24-layer V-NAND Gen1. After the 64-layer Gen4 MLC it was going downward --> 128-layer Gen6 TLC.

if something ERRORMOD related appears i would try this on samsung SATA SSD's LINK
Be sure that in the BIOS the SATA mode it is set to AHCI.

I hope you've done it with admin rights, but i think so.
Last thing you can try, is to simply put the SSD on the SATA power connector with out data cable and wait for 1-2h. They call it "power cycling", in hope that at some point an internal mechanism gets the drive out of serious problems, but is mostly common used for SSD's that are not recognized at all.


If nothing works, you can still open it up by removing the four screws with a pentalobe nr.5, and hang it at a wall (quite nice PCBA), with the text:

845DC-Pro-800GB_PCB-Front.jpg
The first commercially available 3D-NAND Solid-State Drive with one terabyte raw capacity.
It incorporated eight 128Gbit Dies with 24-Layers each per Chip-Package, driven by a 32nm Controller named MDX with three ARM Cortex-R4 CPU's running at 300MHz.
--- Introduced in the 2nd Quarter of 2014 by Samsung ---
