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.
CM7 BTW

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

32gb sd card

Hi guys im having an issue with a 32gb Kingston sd card, whats happening is that everytime i add files to my sd card from my computer it will show them to me that they are there. But once i put the sd card in my phone the new files i transfer wont appear :/. Ive formatted my sd card already like couple times and still does the same. Never did that to my 8gb card, and top of that when i transfer all my data from the 8gb to the 32 only half transferd and when back n fourth doing it folder per folder and just wouldnt show anything on the phone. Any suggestions, thank you

Going to take a guess and say you're on CM? If so I had problems with my 32GB too but on stock roms it works. I had to get a 16GB to use under CM. I'm not sure of the problem but there was my fix

Are you rebooting the phone after putting back the microsd? Sometimes that works.

As matter fact havent tried on Cm, im on MIUI right now. But im giving it one more try with the formatting see what happens if not will go to Eagle Blood see how that goes.

Yeah im since i noticed my sd card wouldnt show up unless would have to reboot. some files have been transfering but like awhile ago i d-loaded the files that needed for the game Modern combat 2 and after finished i rebooted or just quit playing and tried playing again and have to be redowloading the files over and over again since nothing stays on my sd card :/

That sucks, sounds like a bad sdcard. You still got the receipt?
I got my 32gb lexar class 10 with USB SD reader for just under 50 and its been issue free. Never liked Kingston products.

Tried formatting it using the phone itself? Miui is based off cm7 so that could be the issue as well.

Won't let me format it from phone since as soon as I put it in tells me "safely to remove card now" so kinda like automatically ejectects itself when I put it in. N got another problem :/ I bitlocked the sd card in my windows 7 laptop and as I was transferring files my wire was loose and we'll lost the connection and of course gave me files transfer error. But the problem now is that since I bitlocked the sd card won't let me get in it anymore, even though i put my password I put for the sd card. Just says something error with files and blah blah ;/. Can't even format or or anything anymore ;/

Found the solution for this problem with the bit locker > I mounted my sd card on my xp SP3 and formatted it and gave me the ize of 514mb i was like what. But i still did it and when i mounted it on my windows 7 i formatted again and this time showed me the 32gb size . So now its working properly.yeah buddy.

Moving from Weapon X to Miui rom my sdcard was detected fine but then after a couple of days of using Miui I wasn't able to open up sdcard when connected to my pc. It shown that usb is detected on my phone.
It only work when I restore back to WeaponX. I tried flashing different Miui roms, EagleBlood and PhoenixBlood. None detect my sdcard on pc except for WeaponX. I also tried to format my sdcard. Didn't work.
Anyone got any suggestion??

Try reinstalling ure usb drivers or not just restart the computer that would help with me. Or have you tried it with a card adapter?
Sent from my LG-P999 using xda premium

If you've tried it both with the USB cord and with an sd card reader, it might just be a bad sd card. This happened to me with a Samsung 16gb. I couldnt add or delete anything on it. Simply had to get a new sd card. Try out Lexar or PNY if you want a good one.

Odd Issue With a Micro Sd

Hey guys this is my last place to turn before I just go buy a new one but I want to see if anyone at all can help me.
I have a Sandisk 32 GB Class 4 Micro Sd. I bought it off a guy on the xda marketplace and it was in the factory packaging and took me a half hour to get out so I doubt it was fake unless people forge the packaging.
Well the other day I went to copy a file onto the card by mounting it to the computer. It copied just fine but when I unmounted the card and went onto the phone the file was no where to be found. This was off to me so I mounted the card again and it opened fine but there was no file. I then copied it again and it said it worked like it normally does. i unmounted then mounted right away and guess what the file didn't exist.
This is where it gets interesting.
I then mount the card again and select everything and delete it all. It says it works fine. I then disconnect the card then mount it again and guess what all the files are back. Like nothing happened. I then proceed to format in windows by right clicking and hitting format. It didnt do anything. I then go into recovery on the phone and try and format it. Nothing happens. I then connect the card directly to the computer with a micro to sd card adapter that is made by sandisk. It mounts to the computer fine. I then go into Easeus Partition Manager and click format. It finishes and comes up with an error saying There are some error occurred while writing partition chains on disk.
If anyone has any idea please help.
UPDATE: I have contacted Sandisk and they are going to send me a brand new card.

Is the card detected by the mobile?
If yes, try to format it in the mobile itself with the format option.
Also check how much space it shows , before & after formatting.

Try low level format
Sent from my WT19i using xda premium

Could be a duff card but sometimes I have had this if the card has not been fully un mounted try waiting a couple more minutes before removing the card to give the system time to fully un mount it
Or it will not be written to.

Did you press eject USB every time you pull the cable? Not doing it can corrupt your card

dont mean to sound like a **** but you do realize I posted this over two years ago right?
but anyway the card was defective so sandisk sent me a new one.

Nooooo. This is the same issue I'm having! Ugh... mine is a 64 gb and we're about to go on a long trip. I wanted to add more music. And I can't afford to buy one from the local stores. They're too expensive! :'(
I bought mine from GeekBuying.

[Q] external sd card problem

hi guy's!
i have a Galaxy Ace GT-S5730i
and i was having some problems with the internal storage
so i saw this thread by jocala
http://forum.xda-developers.com/showthread.php?t=1757767
that i can use the external sd card as an internal storage
any how .. it didn't work!
but what happened now is that my phone can't read the sd card at all
and saying things like "no such as directory" or something like that
and i can't download the swapsd.apk again cause it needs an sd card to be downloaded to first!
if only i can download the apk from any where directly to the internal phone storage
i can get the swap back to default again!
any help please?!
and yes i am a noob!

Take out the SD card and put it into an SD card reader and put that into your computer and use a free partition program to basically repartition the entire card or delete and format a new partition.

didn't work

but it didn't work

Strange, formatting the sd card usually fixes these kind of problems :/
Have you tried it a couple times? Formatting does fail on occasions. Also make sure you do a full format, not a quick one

well, the sd card is working probably on the pc with the card reader!
so i guess - just guessing - that the problem is in the device it self!
i formatted the phone it self but it didn't work, and i'm going to go with what you are saying
and i will do a full format
thanks a lot

didn't work, does the FAT,FAT32 and the rest of those stuff matter?!

when ever i open "My Files" it says "Your phone does not have SD card inserted" although it is!

take a cloth and clean your SD card area in your phone, also use that canned air stuff and do a quick spray.

[Q] Micro SD card problem

Hello all and everyone who may be able to help me out! I recently got a new phone (galaxy nexus) and decided to root and s-off my evo 3d. After another sad fail at s-off, my sd card was acting up. When its in a phone, it will say the card is blank or it is using an unsupported file system. Upon formatting option nothing happens. When i insert the sdcard into an adapter and put it into my computer, i can navigate to my computer and when i try to get into the drive, "my computer" crashes and i have to remove the card to get back to the start screen. I can use the drive for other things but it just wont read this card and makes the computer freeze. ive tried programs and whenever i try to select the drive, again the program im using crashes. Other cards work fine so it seems the card itself is the problem. worked fine before. Can anyone help me out here?

Had a similar problem a while back seems i had forgot to remove the password before plugging the card into my pc. Not sure how that will help you here tho.

replace the card and check if it is working than the card is defected

Is your phone able to read/detect your card?
If yes then:
Go to Phone Settings> Storage Settings> Unmount SD card> Erase SD card.
Report if that works.

If it's dead, most reputable manufacturers offer a warranty on their cards. Go to their website & look up the procedure for getting an RMA. That's much cheaper than buying a new card.

When the cards in my phone, it gives a notification saying that is an unsupported file system or that it is A blank SD card. When it is in the phone it will not let me erase. when I select Format, it's just kind of stops. and if I select it again, nothing. Can't use unmount or mount as they are greyed out. Wish I could format it.

I had a similar problem figuring out that moving Apps to external sd and then removing this sdcard CAN DESTROY the sdcard controller - better unmount card then remove it or switch phone off and remove it !
Even more worst - it's still working sometimes on any PC with adapter - if you have warranty on that sdcard i would replace it in the store bought !

Maybe i had luck - but since the failure i have been very carefully !
Nowadays sdcards should beeing built that writing more than 100000 times should be possible - so such an error should also not occur
but what the sdcards are very sensitive is heat - temperatures above 55 ° C (131 F) is almost a no go! (or increasing failure rate drastically !)

No when this failure appears - formatting is not possible anymore - the "controller" inside the sdcard is defect !

Just by replying with some information your helping me out. I have tried many SD card repair tools but when the card is in my computer, and if I do anything related to the card, the program just crashes until I pull the card out. I will post a video later. I've never seen this before. If nothing works I'm just gonna get another.
