Sd card issue!

Hi I'm having trouble getting my phone to read the sd card. When I put it in it says safe to remove sd but apart from that the phone doesnt even register that the card is in? I have had the sd card in my laptop for a while but formatted it first. I have a friend and its the same for his android but the 2gb he got with his phone works fine. Is there some sort of file structure that has to be on the sd for the phone to pick it up? Really need help thanks.

No special structure i would fully format the card as fat 32 not quick format .

Ok thanks for the reply. Also read that formatting in recovery mode could work? That was for a diff phone though with the same problem

Problem with sd card on AOKP JB builds

First off I love this rom. I am having a problem with the external sd card. Everytime I have flashed this rom..I set my phone up how I like it all synced up with all my preffered apps. After I do a backup I get a bad sd card message. I try unmounting it then mounting it back and the phone still can't read it. It also did it with another card I have. I have followed all intructions fir flashing this to a T. Anyone else having this issue??
Problem solved. Phone apparently was damaged after I dropped it.

Blank SD card error

Since flashing to the most recent updated ICS I've had issues with my SD cards. Once the phone gets started this error appears....
Blank SD card
SD card blank or has unsupported file system
This error happened with 2 SD cards and at first I thought it was done for but they work fine on my pc. When the phone suggests that I format the SD card I do it (no worries since I backed all pics up on the pc) but I still get this error and it really doesn't format because I still see the files on the pc
Can't browse (from phone or recovery)
Can't mount to mass storage
Can format from the phone
Again I can view files, delete etc from the phone no problem
Is there a fix for this issue? I really need to get my SD card working...
Thanks in advance

my 8gb sd worked fine once reformatted over the pc but the 32gb still picks up fine over the pc just not on the phone..... i just don't get that.... can't our phones use up to 32gb mini sd cards?

32 gb are suported.You where using 32 gb on this phone before this happened?Did you try factory reset?Maybe you can go to CWM and try to mount it from there....

I have tried searching but without knowing the right words to search for I'm stumbling through. Please help me.

Phone isn't recognizing your SD card. Try moving all it's contents to a different storage like a computer and reformat the SD.

I do not have a memory card in phone other than the internal memory. Does the internal memory need to be reformatted? When view how much storage it shows 12gb both on the phone and plug into the pc. If it does need reformatted which way should I go with that? Odin, CWM, etc..?

I think it's a sim card error.

Is this the symbol (sim card)
Sent from my SCH-I535 using xda app-developers app

I attached the pictures is not the sim card icon. No sim card is in it either.

If there's no SIM card installed, then it makes sense for that error icon to show up if it's the "No SIM" error icon.

anyone else want to take a guess? I put a sim card in the board and it active, the icon is still there...
