Root SDXC CM7 CM9 Stock

Micro sdxc cards are 64gb only from the looks of it so that would explain a lot. You need a 32gb or smaller which will probably be micro sdhc.

Edit: so yeah I looked around and sure enough, it won't work. Micro sdxc uses a different format than microsdhc. It needs a different slot you can read more about it here: http://androidforums.com/android-lounge/394162-64gb-micro-sd-work-phone.html
and here: http://www.androidcentral.com/sandisk-announces-64gb-microsdxc-card-dont-get-too-excited

Edit2: Ok so from the looks of some people have got it working by formatting it through the phone. Maybe boot into a rom and then insert the sdcard, then format it which will erase all the data and may take a while since it's 64gb...

Does it only work with FAT32? I prefer NTFS.. just curious

It is currently running FAT32 based on what the properties of my PC says when I connect my phone via USB.

It is cheaper to buy from eBay, I got mines for 72 bucks after CA tax. To find yourself a trusted seller, he/she must have at least 1000 sales and maintain feedback over 99.8% as a golden rule. If close it is based on your judgement :)

EDIT: What is the advantage of NTFS vs FAT32, just curious myself :)

Forgot to add what I am running on: CM7-Reloaded
