Why does my microSD card stop transferring files and crash my PC?

Asked by TechyNinja99
I'm having trouble with my microSD card reader. Whenever I try to copy files from my drives to the microSD card, the transfer stops abruptly and drops to 0 bytes/s. If I attempt to restart the transfer, my PC crashes, sometimes giving me a blue screen and making apps unresponsive. Has anyone experienced this or know how to fix it?

In the future, opt for a well-known brand for memory cards. Cheaper options often lead to more issues, and that could save you from headaches like this!

How old is your microSD card? Also, what brand and model are you using? Sometimes, cards fail or might be counterfeit, especially if they're cheap. If you have access to other devices, it might be worth trying to use the card in those to see if the problem persists. You could also consider using H2testw to check for errors on the card, although that can take a while. Just a heads-up, if it can't even handle normal writes, it might not work at all.

It sounds like the file you're trying to transfer is quite largeโ€”over 70GB! Maybe try transferring smaller files instead of multitasking, as that could overwhelm the card and crash your system.
