SD Card randomly corrupts itself

Bonzay0 · December 15, 2019

So I have a SanDisk Extreme Plus 128GB and I formatted it to Fat32 for my switch.

Sometimes when I move load it to the PC with a reader and try to change (delete/add/replace) it will suddenly become corrupted.

I have no idea if there is an issue with the way I work with it or the sd itself is already ruined for good.

I tried to reformat it so many times, check it with many different softwares and did a clean and long format; I even ran a chkdsk on it as well.

Nothing bad came out of those tests and it always go back to functioning... until it randomly corrupts because one of my file transfers or folder creation.

Is there anything I can do or is it the end for this poor sd card?

Sounds like it might be a bad connection. What you can do is use a blower to blow the dust from your SD card slot.

It could be the SD card faulty. Check if this symptom happens in other device. If it behaves the same, it could be your SD card is faulty.

There's also a very very slim chance, but if you are using an SD card adapter (micro SD to SD adapter), chances is that the lock switch might be intermittent. Maybe use other SD card adapter.
