Probably a bad/corrupted sd card.
You can try and format it again on you pc (use a program like sd formatter)
If that don't work you just need a new sd card.

[Q] SD Problem Help

I've had my HTC HD2 replaced by O2 However I am putting the same SD card back in to the new phone and its not being recognised by the new phone.It asks if I want to format it but still doesnt load up.... What do I do?????????
Connect the sd card with a reader to your computer, dave the data .. format your SD card and try if you phone can read it again
I think the poblem occured due to your old phone which had the FAT table of your SD card locked .. other mobile devices wont reconize it anymore
until you format it again

help
same problem exists fr one of my frds
Try dialing *#*#7378423#*#*, go to Service tests>External Memory (if you are on ICS already - I don't recall GB having this option). It should be able to detect your microSD card as "Inserted/Mounted".
Thank you carlshark
But I`m not on ICS yet...
The update is not released yet for my phone.
I think returning my phone to the store is my best option right now.

maybe the hardware is broken...

WT19i Cant mount any sd card
plsss helpp meee
my wt19i wont mount any sd card i connected the phone on the pc to take some photos and in the moment he did a restart and when start i get a noftitaciton blank sd card i did factory reset hard reset , flash the firmaware but he donte mount the card i took a new card and the new card wont to mount but the old sd card work fine in another phones i dont now what is the problem plsss help meee
and exuse me for my bad english...
i got the same problem here...
anyone knows how to fix it?
my wt19i is on stock GB rom, i rooted it, installed Link2SD, created partition on my sd card, linked some apps to the sd card..
and then i decided to flash my phone to stock ICS.. it succeeded though.. but my phone can't recognize the sd card anymore..
i flashed it again to stock GB, formated the sd card, but it still the same..
I have the xactly same problem. Last night I tried to flash AOS 4.4.x to my WT19i with no good. So I reflashed with last working CM (CM9.1) with 4GB flash inserted. I reflashed, set the phone up for the first time, connected with facebook and installed couple of apps (I have not moved the apps to card - all were in the internal memory). But toady in the morning, I bought a new 8GB sd card and wanted to replace it. And here the problem starts.
When I inserted the card into the phone, it said that the card could be removed. When I look into settings>storage, I see "mount sd card" option. When I click it, it goes grey for a sec and then BOOM, "mount sd card". I tried returning back my old 4GB card, but I still see the "mount sd card" option. Simply, the phone stopped reading any sd card.
Even the recovery cant read the card, which I think is a major issue - I cannoit reflash system, since I cannot access sd acrd in recovery.
Yes, every card I tried IS working - tested on other two phones and three computers.
So I think, is it a hardware issue with the card interface in the phone?

try formatting the Sdcard(external) within the phone, after that reboot ur phone, then connect to pc and transfer files and see
Format the sd card and then copy the files you backed up to the computer maybe you did something like hitting the wrong button on somewhere...

To format external SD in your phone,
Goto, Settings - Storage - Erase SD ( make sure you are erasing your external SD, you can use the size to confirm)
Or do it in CWM recovery

[Q] [Solved] Samsung Galaxy S3 External SD Card Issue

First of all I am sorry moderators if this problem has already been posted.. I tried searching for it and found some solutions that didn't work for me..
I have recently bought a new I9300 and I have a Sandisk 32gb External SD card that I would like to use with it. The card is successfully detected by the mobile but I am unable to copy files to the external SD card.. I have tried formatting the card via CWM via computer card reader both in FAT32 and EXFAT format but none of them worked..
16gb is not enough when you want to try different ROMS.. I hope someone has already solved the problem and point me to the right direction.
Thanks in Advance.
Solution:
So after a lot of search I found that many people have this issue regardinh external SD card in Galaxy S3..This is what solved my problem.. may be it would help you too..
I have 32gb Sandisk Card that apparantly seemed out of order because both S3 and laptop were unable to copy files in it.. I was using the sc card jacket that came with the card itself... .
so instead of just returning it to the sales person via mail I personally visit his office to abuse him..
as it is 1hour drive from here..
but when he chekd the card it worked just fine in there.. and I was like "this is not the same card you are using another one"
Anyway the card reader he used was 3.0.. I am sure many people know this but it seemed to work for me.. i bought the same card reader Lexar usb 3.0 card reader and the same card is working just fine.. playing all the files in the cell phone as well..
Still one issue left and that is I cant copy files within the cell phone via root explorer it says "operation failed due to low memory".. I believe I have to remove .nomedia file that is in there if viewed in the explorer but cant delete it may be permission issues.. anyone have any idea?
Let me know of this helped?
