I have recently switched from the stock ROM (4.4.2) for my Samsung Galaxy S3 Neo+ to Cyanogen 11 (4.4.4 - I wiped data, system and cache partitions before doing this). I have a 64GB external sd card formatted to FAT32 which was working fine when using my stock ROM but Cyanogenmod will not mount it anywhere. It detects the presence of the removable sd card as I am offered to erase it in the storage section in the settings. However, there are no files under /external_sd or /storage/sdcard1.
Is there any way I can fix this and mount my external sd card?
I solved this by converting my external SD card from FAT32 to NTFS using MiniTool Partition Wizard.

Rooted and running Prime 1.4, I formatted and partitioned the micro sd card with sdext, swap space, and fat32 storage partitions similar to a rooted phone's sd card. Now my computer will not recognize the micro sd card. Do I need the sdext and swap space, or can I do a complete fat32 or NTFS partition?

For me, I just use the normal Win format command to have a FAT32 partition.
After formatting the card on linux via gparted, android shows the sd card as damaged and asks me to format it? How does one mount an ext4 card?
I am just guessing, but since the SD has to be compatible as USB Mass Storage Device, it must be formatted in FAT32. Windows for example cannot handle linux/UNIX specific partitions like ext3 or ext4.
well guys I recently bought Samsung galaxy s4 19500 and for that I bought Kingston 32gb class 10 micro sd card. it worked flawlessly
but today when I unmounted the sd card from my galaxy s4 and put it in a card reader and connected it to my pc, windows detected it but asked for to format it.I clicked format microsd 32 gb , it wont format by quick format option for NTFS, FAT32 and EXFAT formats saying windows is unable to format sd card.then I unticked the quick format option and SLOW FORMATED in FAT32 .it continued to format it till around 99% then it said cant be formatted. Now when I mounted it back in my S4 , it says blank sd card and is not detected.
ANY solution to this issue?
regards

Just mount it in Linux. Delete all partitions using "gparted" and unmount the card and remove it from the reader. Mount it and Create the partition you want like fat32 or ext4. I won't recommend NTFS due to the fact that it very restrictive filesystem. Your card is perfect and you just need to create and mount right partitions.

thnx bro , issue was with the card reader
I am using it in FAT32 format now
I am running cm12 nightlys and have just bought a new sd card,Samsung 32gb EVO, from ebuyer and it will not mount. Is it the rom? or do I have a problem with the phone hardware ie the sd card slot?
Hey if your sd card's file system is exFAT, try to format it to FAT32 and try again.
Hope it works
I have a SanDisk 32GB Class10 SDHC MicroSD card which was working fine with AOSP EXTENDED 4.4 in Adopted Storage mode in ext4 format by default.
One day it just stopped working on it's own showing a "Corrupted" error in storage settings.
So I reformatted the card in Android again as Adopted Storage, and it successfully completed the formatting.
But it started showing a new error "Corrupted/f2fs"
And has never worked ever since.
I have no clue why this formatting in Adopted Storage is changing it's file system to f2fs, as it was ext4 earlier in the same room.
I tried formatting through Windows and then in Android Adopted Storage settings but ended up with the same error "Corrupted/f2fs".
I did some research to find out abt f2fs and so I rechecked if my /system and /data partitions have ext4 as the file system, which I found true.
So there could be no reason for a rom flashed on a ext4 based /system and /data partion to format a SD card to a f2fs filesystem.
I tried changing roms to AOSP EXTENDED 4.5, RR 5.8.4 but formatting as Adopted Storage no longer works on this card.
Although formatting as portable storage works just fine.
I tried with another SanDisk 2GB card and it started showing the same error "Corrupted/f2fs".
I need some confirmation on, if the SD card is kinda half dead or something and needs to be changed.
