I think I broke my Micro SD card - heeeeeelp please

[X-pert74]

I got a 128GB Micro SD card a day or two ago, for my Switch. I took some screenshots and videos in Zelda while it was in the system, and I wanted to upload the screenshots from the micro SD card to my computer. So, I plugged them into my adapter, and it said the disk needed to be formatted. I plugged it back into the Switch and it was fine there, so just to make sure I transferred my screenshots/videos to the Switch internal storage (so I at least didn't lose those). Then I plugged the micro SD card back into the computer, and it wanted to format it as a 1.88MB-size drive, for some reason, even though it's a 128GB drive. I said ok, because I figured I could reformat it later if it didn't work, but umm... I have yet to figure out a way to reformat it as larger than 1.88MBs. It did show up as 128GBs when I first put it in the Switch, so I don't think it's a fake drive, like some places online seem to indicate. When I plug it back into the Switch, the Switch says it doesn't have enough free data, and I need to clear some data off while it's plugged into my computer (it then says "no SD card detected" when I go to the data management page on the Switch). I've downloaded some free programs that are designed to repartition disks, and also tried cleaning and repartitioning the disk with command prompt, but nothing seems to be working. My micro SD card seems to eternally be arbitarily stuck as a 1.88MB SD card.

My computer is Windows 7 64-bit, if that matters. The micro SD card came with an adapter to fit it in regular SD slots, and I'm using a Promaster Digital adapter thing, plugged into my computer via USB.

Does anyone have any advice? I'm not sure what else to try at this point. The thought that I ruined my micro SD card I literally just bought is pretty upsetting.

No expert here, by any means, but i've dealt with my fair share of bad format jobs.

What I would do is try to find a 'disk rescue'(sic) utility for your windows 7 pc, one that could diagnose and identify bad disks, and use that. It's a bit strange, since a 1.88 MB drive (MBs looks like MB/s to me) is strange. I would think that the 1.88 MB is a utility partition, used for addressing data allocation. You really need something that will start from scratch; maybe fdisk? i dunno, i haven't used windows in a while.

Anyways, I've seen this more than a few times, and I'm not sure what to call it (header knotting, maybe), but what you really need is a lower-level formatting tool that won't bother reading anything on that card, and instead just do its business. These tools are much rarer in this past decade because the threat of malware has meant their suppression. I don't even know if there are tools available for SD cards for rewrite services like this. (They exist, but I'm not sure how available they are.)

EDIT: This seems relevant superuser.com/questions/202160/how-do-i-format-my-8-gb-usb-drive-to-fat-fat16-in-windows-7 superuser is a bit harsh, I don't have time to translate it at the moment, but maybe later.

hope this helps.

EDIT 2nd: www.wikihow.com/Format-an-SD-Card This might be easier. i don't know if you've tried it. i'm not a windows user, myself, so i can't confirm/deny if this actually will work.

My computer doesn't even recognize that it's plugged in anymore when I try to plug it in. My Facebook friends were debating the possibility of it actually being fake or not, but I'm just fed up with it at this point. I'm gonna try and return it, and I'll try those tests with the new card I get. Thank you for your help.
