Question External 2TB Samsung T7 SSD shows "(1TB)" in its name ?

[Kat345]

Hi

I bought a new 2TB external Samsung T7 SSD and wanted to install Linux on it.

During the Linux Setup where I had to choose the drive to install to
the name of the external SSD shows up as "PSSD T7 (1TB)"

Properties show 2TB free space though.
The serial numbers on the box and the device match.

This seems fishy to me, why would it have "1TB" in its name?

Any ideas why that is?
Thanks

Highly likely just an error made it trying to get the models out fast. That or less likely, the drive saw Linux and thought, or he's going to dual boot 50/50 so lets call ourselves 1TB. 🤣

As long as you have 2TB free space that is all that matters. I would just change the name to something more elegant anyway, even if it said 2TB.

The name of the SSD in the file viewer is just "Volume" as I didn't bother to give it a name when I wiped and formatted it.

The name "PSSD T7(1TB)" shows up during the Linux setup.
So that name must be stored somewhere else and does not get changed when I rename the drive nor when I format it.

How does CrystalDiskInfo or smartctl identify the drive?

It shows "Samsung Portable SSD T7" in crystaldiskinfo and "PSSD T7" in smartctl.
Suprises me that there are two names stored in the firmware.

I tried the Linux setup on a 2TB internal SSD from a different manufacturer
to see what would show up and for this one too the device shows up as
"[model name] (1TB)"

So I guess Linux is adding "(1TB)" behind the device name for some reason.
I wonder why it falsly attibutes 1TB in both cases.

One tool may be getting the model number from the bridge IC, while the other might be getting it from the SSD behind the bridge.

This is the PCB out of a T7 Shield:

The bridge IC is Asmedia ASM2362. It has a companion serial flash memory, Adesto AT25DN011. If this chip is absent, the USB mass storage device would identify itself as a generic Asmedia device. When the chip is present, the bridge firmware uses the stored OEM Product ID, Vendor ID, model name, serial number, manufacturer name, etc.
