Chosen Solution
I have a Galaxy Note 10.1 2012 tablet with Android Version 4.1.2. It keeps running out of storage space, so I decided to mount a 32GB SDHC microSD card in the slot. I installed the card correctly, and the tablet sees the card, but after I mounted it, no available storage space info is showing in the Settings, Storage area under SD Card. It offers an icon on the home page, when I click to format the SD card, it acts like it does it, but the sd card icon returns to the black frame in the corner, and when I return to Settings, Storage, SD Card, all it offers for choices is Mount SD card. I suspect a faulty SD card slot, but wanted to get your opinion before I spend any money on a possible fix. I have a newer tablet that I purchased last year, and it works A-OK, but would like to keep the older 2012 tablet working as I’ve gifted it to my 80-yr-old aunt to play slots! Any suggestions?
Put the card in a PC or Mac. Right-Click the Card when it shows up. On a Mac, select Get Info On a PC, select Propreties Check that the card is formatted as “FAT32”, not “XFAT” or “NTFS”. If it is not, you will need to backup the data and format as FAT32.
I cannot check the SD card. It is installed in a tablet in Delaware, and I’m in Albuquerque! However, I can tell you that it was a brand-new 32GB SanDisk microSDHC. Is there a way to check the properties of a microSD card on a tablet?! This is a great possible fix, and I surely appreciate your suggestion.
