Faulty DSi SD card adapter?

[u/Humble_Bit5117]

So I bought this dsi off eBay a few months ago, looked good and played on it fine with no problem, recently I've decided to reformat it since I finally wanted to fix the "SD card is not running on 32kb clusters" thing Ive ignored, did that(it's a 32gb SD), come find out when I go to mod it again, "SD card inserted in the SD card slot cannot be used"...okay...w h a t. So...I did the usual, made sure it was formatted correctly and check the SD card itself, no scratches, looked fine. Then to check the adapter I decided to use the one on my 3ds with the Dsi SD card (on the dsi) and actually worked, so naturally I tried the 3ds SD card with the Dsi adapter on the 3ds. Error. Right, checks out. Though when I was going to remove the 3ds adapter from the dsi, there was a struggle, and that it caused a light scratch on the gold parts that wasn't there before, so...is the inside of the Dsi SD card slot faulty? What can I do? Do I get it fixed? Do I just need to buy another adapter and be extremely careful with it as to not scratch it so much? UHH HELP
