damage samsung 980 pro

[ShadowAi12]

Hi,

I have a problem with my Samsung 980 Pro SSD. I accidentally damaged it while removing my graphics card — a resistor (marked in blue) got ripped off, and some other components were also damaged. I need the specifications of these parts because the SSD isn't working properly in my PC.

It randomly causes blue screens, and afterward, it becomes invisible in the BIOS. However, when I connect it via USB, the drive works stably, which makes me think something might be missing or malfunctioning on the PCB, causing issues when connected internally, while USB limits its performance but allows it to run.

Right now, I've replaced the missing resistor with a 10 ohm 0402 one.

Well, if the original value of the resistor is unknown, I might advise to use a higher value, like 10k or 1k. Because usually it's just a pull-up or pull-down resistor. If this card works well together with an USB interface card, it might be that there is such a resistor existing on the USB interface card. It's worth to make some measurements on those solder pads dismounted and mounted in the USB adapter card.
If you mount a 10R and the behaviour of the board is not as expected, the value might be too low.
You can also measure where those pads are going to. It looks like they are connected in a way with the slot pads. The slot is documented, so if it's known, where those resistor pads are connected to, we can say what value the resistor shall have.

Thanks for the reply. Without that resistor, the drive doesn't work, so it seems to be critical probably a pull-up, since one pad had a voltage close to zero and the other (the right one) was at around 1.8V. I don't have resistors with values lower than 10 ohms in this package, so I'm asking to make sure I order the correct parts.

When the drive was running via USB, it worked fine I copied data for an hour without any issues. On Linux, I have a theory that the drive was limited in power (possibly due to limited data bandwidth), which helped it remain stable. I suspect the reason it fails when using the native connector might be because that resistor has too high resistance.

I forgot to mention that when I booted into Windows and launched HWiNFO or CrystalDiskInfo, I got a critical warning it was constantly reporting a temperature of 85°C, and the drive's health status was 97% (marked as bad). After some time, usually less than 10 minutes, Windows would freeze and throw a blue screen with the error WHEA_UNCORRECTABLE_ERROR. When I removed the drive, even within 2 minutes after the crash, it wasn't hot, so I doubt the 85°C reading (though I can measure it to be sure).

I also have a suspicion that the controller might be damaged. I'll try to find documentation for that connector and see if I can find the correct component values.
