[Q] cannot mount sd card on cm12 - Galaxy S 4 Q&A, Help & Troubleshooting

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

Unable to format SD Card

any one got any ideas??
im still running MCR 2.8 and i seem to have the same problem. i am unable to format my sd card.
Hi,I have same problem after updated to modaco 3.1,I can unmount the sdcard,but after I click format nothing happenes,and I cannot install ra-recovery,maybe because a first problem...
Anybody know how to solve it?
Same problem here... i tried everything. im pretty sure this card is dead. It was a samsung and happened after i used iSyncr and removed it not "safely" -
Try to format the card with windows, trough your phone or, if i't not working, with another reader, like a camera or a sdcard reader.
Use this software to format it:

Do a FULL format not a quick one. After you finish, format the sd card again with android and create your ext.2 partition if necessary.
Let me know

[Q] CM 10.1 Doesn't Recognize my sd card?

I have installed CM10.1 on my Canadian Galaxy S4 and for some reason it will not recognize my micro SD card.
The card is formatted to Fat32, and stock TouchWiz reads it no problem. When I insert the card while I am running CM10.1, I get a message in the notification bar which says "Empty SD card inserted."
What is wrong?? Can anyone help??

Are you sure it's Fat32? What size card?
Most SDXC 64gb cards come formatted as exFAT these days (aka Fat64..). CM10.1 will not read exFAT. It will read Fat32 and EXT4. Stock rom will read Fat32 and exFAT.
Thank You

Thank you so much! This was exactly my problem and everything is working perfectly now.
I had the same problem. Does the device also read Gameloft data on the external sd as well? It's the only thing I have yet to figure out...

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.

Removable MicroSD card detected but not mounted

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.
