Hi,
Is the sd card loose in it's casing?

What have your tried?
Tried SD in a different Phone?
Checked the SD for errors?
Is the SD loose in the carrier?
Formatted the SD (fat 32 and primary partioion) from a PC?
Tried a different SD in your phone?
It does help if you do the basics and add what you've done in the OP

No, I'm never inserting my SD card to any other devices
Previously i checked it for errors,and got cleaned
After I purchased it,i haven't formatted....
I found this "un-expectally unmount error" from this last week...

I had similar issues with my sensation my sd would unmount unexpectedly it would vary from rom to rom. I found that if re flashed my current rom without a wipe it would correct the problem. It worked in my case hope it helps

I would try the reflashing rom idea above as its easy.
If that doesnt work transfer all the sd card data to your computer then format the card. See if that fixes.

[Q] 64gb Micro SD Card?

Hi guys, i have a 64GB Micro SD and i can't seem to get it to work with my device, Im running the CM10.1 Jelly Bean ROM and when i put the MicroSD Card in it said there is no external storage available.. Is there any tweak i can apply to get it to work or does the hardware just not support cards that size?
Thanks,
Dan.

hmm,
i am out of ideas
maybe go to the CM10.1 Jelly Bean ROM thread and post there your issue
or wait until someone come up with something
but many users have sdcard with that capacity and works fine
best wishes
edit:did you reboot the device?

i have rebooted and it still didnt work,
when i go into settings>Storage and click on mount SD it comes up saying " The SD Card is blank or has unsupported files." So i click that and it comes up saying "Format SD Card, All Data on your card will be lost." So i click format and it says "SD Card is currently being checked"
And thats it left it like that for 20 mins nothing happens.
Any ideas?

Boot in recovery in format sdcard their as I formated my sdcard in recovery n then it started to work if it is not getting detected in recovery make a normal boot go to setings-storage-format sdcard it vll work
hit thanks if I hve hlped you

For finding the format of the card- connect it to pc and then check what format it has (tell me your os, if you need more information in finding the format).

[HELP} problem with sd card

hello, i have a 4gb microsd with my android phone
suddenly one day it stopped allowing me write or delete files from sd card, only read operations are done
normal check with windows failed
i tried to format with gparted and diskpart everything failed,
it doesnt have a lock, tried from usb card reader also
what should i do know??
(did a lot of googling tried many formatters none worked)

Try these:
1. Unmount SD card in your device, and mount it again.
2. Connect it to a PC using a card reader, and run CHKDSK.
3. Format the SD Card in a digital camera or a Nokia phone.

Hy,
No,i didn't know that this is necessary. What file system is needed? NTFS,Fat32 or is there a Special System for Android
Do i need a special Software to format the Card or can it be done with Windows?

It can be done with Windows. I don't know if this will work or not, but just play around a bit. Maybe Samsung formats it for their phones only ?
