Hardware SD Card problem

[SommaCruz]

Hi people, I have gained a 256GB SD card from Samsung. I have used sometime on my switch but it caused a lot of problems. I got some errors while playing games, lost game saves and Choidujour can't find all updates files. I have checked the SD card using H2testw and it show no errors. I was using it formatted EXFAT and my switch have 6.0.1 firmware with 6.2.0 Emunand plus SX OS 2.5.3. Did anyone had same problems with this card?
Sorry for my bad english.

I was using it formatted EXFAT

That's your problem right there! The exFAT driver on the Switch isn't the greatest. I would suggest formatting it with FAT32 instead. I'm not sure what OS you're using but if you're using Windows then it's not going to let you format that card using the native format utility. Do a Google search for "Windows GUI version of fat32format - Ridgecrop Consultants Ltd" and use that tool instead.

Set your "Allocation unit size" to "32768".

Thanks Fanboy, I will try it.

Well, I have formatted in fat32 and got the same errors. I will make more tests, but problapr the problem is the card.

H2testw - did you do the "write + verify" or just verify? Should do write+verify.

Files on sd card could be corrupt, if you copied corrupt off of your SD card before formatting as fat32 then put them right back onto your SD card. Try to redownload all files fresh and setup sd card again.

Also have you attempted same thing with another known working sdcard without issue?

I have done write and verify and it showed no errors.
Now I am using a sandisk 64gb card exfat formatted and it work without problem. Emunand and the games runs perfectly on this card without errors. Some people say that formatting the card on switch could solve the problem. I will try it.

Format with this if issues persist : https://www.sdcard.org/downloads/formatter_4/
Choose "overwrite format"
It will take a long time.

Hope all works well.

After all these things done it is still showing errors. I have tested the card using H2testw again and no errors was found. I don't know what else to do.

What "errors" are you're getting specifically?

What "errors" are you're getting specifically?

When I use choidujour for emunand update, it doesn't find all files and I can't update. Some games close when I try to play and giver errors message. I have lost save games, because the data was corrupted. I know that it sounds like fake sd card, but I have checked it and doesn't find any trace of fake card.

Can you try another SD Card you KNOW works?

Now I am using a Sandisk 64gb and there is no problem.

Maybe it's not a fake but simply faulty or a card that failed QC and was supposed to be thrown away. Is this a new card? Where did you get it?

 

[Dust2dust]

Personally, when I want to test an SD card to see if it's faulty or not, I just fill it up completely with a BIG scene release, something 12GB or more, copied over and over on different folders (01, 02, 03, etc) until completely full. Then I run an SFV checker recursively in each folder on the SFV file to see if any file is corrupt. If everything checks ok, the card is good and genuine.

Copy a massive file over to the new SD card and see if it just stops at like 8gb. then it's a fake card.
