SD card not working anymore

[arthuro555]

Hi, sorry for my bad english,
I buyed the sd card with the most quality and the highest price of my local informatik shop, for my rpi.
I installed kivy pie for a project and started raspi config in root. i updated the tool and changed the keyboard layout (I'm frensh) , And then expanded the filesystem. I restarted as prompted the rpi, and it maked a blackscreen for about 15 sec and displayed errors messages fith ext4 saying bad blocks at system commands. then it started a boot loop and didn't displayed again an error message. When I try to use a partition tool, win32disk imager or sdformatter, It needs 10 minutes for every operation and say at least failed. Diskpart and chkdisk crashes when executing on that sd card. The windows partition tool says E/S failed. Can somebody help me that sd card have costed 50 euros pls I don't want to have to buy another.
Thanks.

If you bought a defective card you should be able to return it for a refund or exchange.

You didn't say what card it was you purchased (make, model, size), but if that shop has the SanDisk Ultra A1 cards, that's what you should get. A1 rated cards are much faster when used on something like a Raspberry Pi (compared to most class-10 micro SD cards).

or.... you may have been duped to buying a fake "branded high-quality microSD card" as those are quite rampant nowadays.
Some stores dont know they are selling fakes/damaged microSD, some knowingly sell fakes.

please take time to read the contents of the link below to help you assess if your microSD card is fake and/or damaged

and as HawaiianPi posted, you should be able to return it for a refund or exchange.

OOC, assuming you wrote the card on your Windows computer, were you using a "built-in card slot" or an external, USB-based card reader/writer? (The latter are usually more reliable than the "slots" on older netbooks/laptops etc. since the "slots" may not be fully SDHC/XC compatible, unless the "slot" is labled to be so - very few are, IIRC, I've only seen one on a Windows tablet).
