Problem: SanDisk SD card not found by phone or PC
«My SD card was working flawlessly in the past few days. Suddenly, I went into the media on my phone today, and it showed nothing. I go into my phone settings, and it says there is no memory card detected. I tried SD cards from three other friends, and they all registered fine on my phone, so that isn’t the issue. I then tried my SD on my laptop, and the laptop won’t even recognize I inserted a memory card. What could I do? This is a pressing matter because I need one of those videos off of my SD card by next week.»
This is a snippet we picked up on forums.sandisk.com, one customer’s SD card has a seriously malfunctioning problem, and soon this post was followed by other old and new customers.

And mostly, they are using types like SanDisk Extreme Pro/Plus micro SD/SDHC/SDXC card, and a small Digital camera group is using XQD card.
No matter how large capacity you’re using, the minimum 2GB/4GB to medium 32GB/64GB/128GB to maximum 256GB/512GB, it’s the same consequence when the memory card is reading, detected or recognized by a device. You cannot take pictures, install apps, transfer files to the computer, or simply cannot open the SD card.
