Hardware Misc Problem with SD Card

[JhulkerCraft2]

Hello everyone, I would like you to help me solve a problem that happened to me 3 days ago, I had my micro SD inserted into my laptop calmly transferring files to it until suddenly a few seconds after the files were transferred the tab was closed and it was ejected the card out of nowhere, I tried taking it out and inserting it again but it didn't work, I also tried inserting it into my phone and it didn't work either. Please if anyone can help me I would be grateful.

Evidently it was not inserted properly, did not make full contact, or some pin was dirty, or there was a vibration that moved it slightly out of the slot; either way, the micro SD became corrupted during the copying process. It can happen. It is not that uncommon an occurrence. You'll have to reformat it, I'm afraid.
But if the PC doesn't recognize it at all when inserted (it doesn't even say it needs to be formatted), then it's worth throwing away, sadly...

Thanks for responding, and it's too bad that I lost a 16G micro SD that way, now I'll have to buy another one, I thought there was a way to recover it. Also thanks for responding

Hold on a second. Maybe other users can suggest something else. If I remember correctly, you can use the command line "chkdsk X: /R" to possibly repair a corrupted filesystem (X is the drive where the SD card is inserted). If even then PC does not recognize the presence of an SD, then unfortunately it is an unrecoverable mechanical damage.

I have an SD card from an R4 card which appears dead in all devices but I got one of those USB card readers and found that if I plug it in and out about 20 times quickly and be a little rough with it - it comes to life... until I remove it again.

Sometimes I would spend 10 mins repeating the process until it worked but luckily it worked long enough to get what I wanted off the card.

I only recommend trying the above with a USB reader because if you damage the contacts on the reader it's cheap to replace.
