I faced a problem with my 64gb. Sandisk micro SD and I solved the issue and I thought about posting the solution here that might help some of you.
so... the issue I faced is how to get TWRP recovery or CWM to mount my Ex sd card.
basically the problem is that the card is formatted in exfat or NTFS and in both ways it won't be recognized by TWRP and the only way to formate it in fat32 is by only one software because windows can not format more than 32gb in Fat32.
and here is how:
first: download EaseUS Partition Master Home Edition from this link http://download.cnet.com/EaseUS-Part...dlPid=10982635
Second : Now you can see a list of all of your hard drives. Note the one highlighted in blue on the grid. This is my 64GB MicroSDXC card in my USB Card Reader. Obviously the location of your card in the list may differ dependant on the number of drives in your computer
You’ll need to right-click on the drive in the list representing your 64GB MicroSDXC card and click “Format partition”
Third : You need to select FAT32 for the File System, and 32KB for Cluster Size.
EaseUS doesn’t immediately apply the changes you specify. Instead, it queues them up so that you can review and revise them before you commit to having the program affect those changes. then we need to press the Apply button.
that's it ... now you can enjoy your 64gb MicroSd and you can mount it in TWRP or CWM recovery .
