Is there a way to check for bad sectors on SD cards without taking it out?

I don't want to take the card out because I don't have a card reader at the moment and I prefer not to touch the slot since I heard it's easily broken and hard to replace.

You can check the card status in Hekate. It will tell you some info like if it's a fake card, format type, capacity, and you can also run the "Benchmark" tab to test the speed.

Also you can use UMS tool of the Hekate's NYX to mount the card as a UMS device on your computer and then use H2Testw (https://www.heise.de/download/product/h2testw-50539) on it.

I didn't know this. I thought H2Testw would wipe the sd card to test it. Good to know, thanks!

Nop, H2TestW can test the free space.

The problem is if you have a fake device, sometimes when you write on last part of the device you really overwrite data at start and you can end with a corrupted data. but if only is a damaged sector H2testw can find it using the free space on partition.

If you find bad sectors on the card is there a way to repair it the same way chkdsk offers? Is there a way to use chkdsk to repair the SD card without taking it out?

Having gone through this myself...hekate showed everything was fine. In fact, it was not fine. 300,000+ bad sectors on a new sandisk 512gb.

You got a fake card, if you can ask for a refund

Hekate only shoy you the state of card reader and sd firmware. Unless you make a full test

Should have done a h2testw test on the card before use.

Was a brand new card from microcenter. Bought two, only one had an issue.

The electronic devices could be bad even just from factory and a original one. ask for refund or change and TEST the new one before use. H2TestW is your friend.

If there are bad sectors, the card is dead. They will spread VERY quickly on as SD card. They are soooo cheap now... I mean a 1TB card is the same price as a single switch game now so its not a huge deal
