I was just using my phone and then I clicked on an app that i had on my sd card and said that it couldnt be found, then it said that i had a blank sd card and that it needed to be formatted. I tried everything; pulling the battery, mounting, remounting, putting it in and out, tried to mount in recovery, tried to format in recovery...... NOTHING WORKED! So then i tried to plug it in on my computer (windows 7) and it wouldnt mount, so i couldnt format it.... Is there ANYTHING I can do!?!?!!?!? someone please help me cause it is a 16gb sd card and all i have left is a 2gb one... HA that wont work for me. Any help is appreciated!!

Pull sd out of phone and use a card reader to see if it can be read from the pc. If you can read it with the pc, copy all your files to the pc and then format the sd fat32. Once formated put the files back on the sd and put it back in the phone and see if it works then.

How old is it? Sometimes they just go out, especially with heavy use.

If ur phone has a recovery mount usn on phone recovery. Then scan the card with a data recovery tool. Its worked for me in the past

I have tried that and it gives me an error and says I can't mount it.

have you ever pulled the SD card out of a device before Unmounted it? Sounds like the the chip inside is dead. There are some places that you can take it to and they can pull the info off of it. its not cheap but they do exist. It all depends on if you really want the info off of it or not.

Have you tried "SD Card Tester" from the Market, Or H2testw 1.4 for the PC?

Problem with SD-Card

Hello,
Problem with the SD card.
If you start from sleep mode appears card was removed and then can be used again, see on status.
This has been adjusted after a few weeks.
What could be the cause.
:crying::crying::crying::crying:

I am also seeing this issue, it looks like card is unmounted and mounted again automatically....
What do you mean by adjusted after few weeks? you don't get it now?
I am still trying to find out why its happening, might try to format the sd card and will try...

I meant earlier was the SD card mounted, and I had always unmount any mount.
I have already formatted the SD card, itself effectively.

Is it still happening after formatting the card?
Also have you formatted the card from recovery or from system settings

Hi,
If I format the card, the same error occurs.
I'm going to swap the card and test.

Let me know how it works out
Sent from my SPH-L900 using xda app-developers app

OK, I think I am able to resolve my issue. I haven't seen that message for last one and a half day where I was seeing it 2-3 times a day.
Here is what I have done. I have removed the card and formatted it from the laptop, reinserted it properly again and format it again in the phone.
I think the key is how you insert the card, there can be some tension in the strings which can push the card back, so make sure while inserting it is going in properly and there is no friction while inserting.
I will post if it doesn't happen again for another 2-3 days...

MicroSD card losing connection with phone = MTP issues on JB 4.1.1 official release

Every time I flash anything based on the official JB 4.1.1 release, my 32GB MicroSD card (Patriot brand?) freaks out. The phone will say it's "unexpectedly removed" and then adds it back in, and removes it, over and over.
It's happened on all three JB 4.1.1 ROM's I've tried.
I thought my MicroSD was going bad so I low-level formatted it in Windows (hated doing this) and still had trouble. But ONLY with the card in the phone. Windows usually liked the card just fine.
So what I did to resolve it was use Titanium Backup Pro to "freeze" the "MTP Application". After doing that, my MicroSD works great in the phone and AFAIK, I haven't lost any functionality. So I'm not sure what the "MTP Application" is or does, but so far.... so good.
This post is just a heads up to others, in case anyone else runs into this problem.
Or in case anyone wants to tell me WTF is wrong.

Ive had this issue as well twice. Both times I had to format the sd card in my pc and it will work fine for a while. Im curious to know if you are using es file explorer? Im thinking it might have something to do with this issue.

Hmm come to think of it I just recently purchased root explorer about the time all this started but surely an app couldn't cause this issue? Heck I dont know it happens so random it hard to pinpoint the problem thats causing it. If I figure it out I will let you know

Ive been trying to duplicate the problem all day with no success. However I have froze the MTP app so maybe thats what the cause is? Would you happen to be using a sandisk micro sd? Because I am..
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

Ahh hah I duplicated the problem on my phone anyway. I used the my file app to move a rather large file from the internal sd to my external sd and afterwards it lost connection. I had to remove the sd card and install it several times to get it to mount back again. Im not sure if its the moving of the file or the my files app itself that is doing it. I also noticed the media scanner isnt running after moving the file. So I hadnt pinpointed the exact cause but im dang sure getting closer. And I dont think its a bad sd card because I tried another and it did it with it too
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

You were able to duplicate it even with MTP frozen?
Wow, I have yet to recreate the issue with MTP frozen.
My SD is a Patriot brand. Purchased at Fry's Electronics.

Yea it happened with MTP frozen and unfrozen. Ive tried freezing the my files app and every file explorer on my phone. I just cant put my finger on the cause it happens so random. But it seems me and you are the only ones having this issue so im wondering if we didnt get a bad flash when we updated. When I updated via kies it did not do a full wipe update it did what is known as a dirty flash which I never do because you end up with issues like this. So if we continue to ask each other questions we will eventually figure out what the common link as far as if its an app we are using and things like that.
So did you update via kies or odin?
If you updated via odin where did you get your firmware file file from and if you used odin was it odin on the pc or mobile odin?
And was your update a full or a dirty flash?
We are gonna figure this thing out one day lol.....
Edit.... well apparently we are not the only ones having this issue. Over on droid forums there are several s3'owners most on t mobile but anyway it appears there are a few phones out there with this problem and the only fix is to replace the phone and sd card because the phone ruins the card by unmounting it without stopping it first. My phone is still under warranty so I will be calling ATT tomorrow for them to replace my phone and throw a fit for them to replace my micro sd. I paid 48 bucks for this card and I think ATT should replace it since their faulty phone ruined the card

Wow.
I had the problem with two or three different ROM flashes. So it wasn't just one ROM flash.
Each time, freezing MTP Application has resolved the issue for me.
I'm going on ~4 days now with my current ROM and no more issues since freezing MTP.
Maybe there are a couple different SD card related issues out there.

I had the same problem with ADATA and Kingston brand sd cards. I tried the Sandisk 8GB from my old phone and no problems so far.

Freezing the mtp app has seemed to slow it down. The only problem with freezing mtp is that is how the phone mounts to the pc. Mine just did it again but I unfroze mtp to hook my phone to the pc and right after I backed some stuff up and unplugged it, before I could freeze mtp again it unmounted the card. Ive also tried several different sd cards and several different sizes even tried a 2gb Samsung card with the same results. Im thinking hard about going back to ics to see if that will resolve the issue. ...

I found that my 64GB card was not recognized by the newer kernels - when I use the older kernels or stock, it is recognized, otherwise, the ROM attempts to read the card, and then states it is 'ready to be removed'.

Try reformatting the 64gb card to a fat 32 file system. 64gb cards come formatted exfat and some s3's have had trouble reading them. Put it in a pc into the card reader and open my computer. Then right click on the drive thats showing your card. Ex drive E or F. Mine is drive N. Once you right click on it click format and a box will pop up and you will see the box that says exfat. Click the drop down box and change it to fat32 then click format and your done. Once it finishes put it in your phone and it should recognize it...

Well my 64gb micro sd came today from Amazon and from what ive read on xda and the net I would need to change the file system from exfat to fat32. So I put it in the pc pull up mini tools partition wizard and it gives me no option to format it, I try windows no option for fat32 only ntfs or exfat so I try a couple of others with the same results. Then I try hp format tool and finally format it to fat32 then put it in my phone and it says its damaged and needs formatting so I do and put it back in the pc and im back to exfat. So it seems to only work in my phone in the exfat format soooo im just gonna leave it alone. Oh I even tried formatting it in command prompt and changing the file format and it fails so now im starting to wonder if thats what happened to my old 32gb card and why I suddenly starting having trouble out of it when I updated to jb is because it was fat32. Maybe this new jb dont handle fat32 well or maybe my s3 dont like fat32. Hell I guess its just a mystery. ....
So I would suggest if your having sd issues try formatting your card to exfat and see if that helps the connection issues

[Q] extSdCard gone! Please help!

My external sd cart (named extSdCard) on my sgs3 747 Lh9 dissapeared after backing up with rom manager and then pushing a file over from my computer to my phone. I tried putting it in another android phone and it called it a blank sd card and it wouldn't even open! Please help me figure out how to fix this, I have alot of important stuff on my external sd.

Seems like it got corrupted. You can try out some of the file recovery apps from the market but I've never used any so I can't vouch for them.

Don't format your sd card yet. This happened to me several times. It's the phone itself. The card doesn’t stay locked properly. You'll notice faster battery drain for a few days if it's like anything that happened to me. Back up your sd card if possible. Reinsert the card while the phone is off. I push the metal guard in a little so it stays in. Turn it back on. It should work. You can follow what I did at your own risk.

Similar thing happened to me a few days ago. Notification bar said that the card was damaged. I simply put it into my PC card reader and ran Mini Tool Partition wizard (Google the free download) and I did a scan and fix and I did lose some files from a recent folder transfer (which is what I think caused the problem) but the card file system was quickly repaired and no reformatting was necessary. In other words, the card did not have physical damage.

(solved) 64gb sd card stuck on read only

Hey! So my 64gb SanDisk microsd card was working fine then the other day it decided to switch to read only, and nothing I do will fix it, windows refuses to format it, ubuntu says it did but the data remains untouched, nothing works! Any help?

something similar happened to me with mine. I had to reformat it and I lost everything that was on it but it works now.

Same Issue
I has been dealing with this issue ...now with two SanDisk Micro sd cards XC I, I did tried to format in almost all the know ways...tried Linux, Windows, command line, Different adapters, Different computers, tried with the Storage feature from the Android OS,
Now I have two beatiful 64G micro sd cards....READ ONLY. Also if you browse the content in the file explorer from the computer the Delete option is not listed in the explorer.
Is there any magic tool that can remove this read only feature from the cards????????

Same issue here: did you update ROM to 4.3 version? I read that it could contain a setting within the platform.xml file that you find into system/etc/permission folder. See this
I tried it but with no success.
I hope you're luckier

Btw i sent it back to Amazon asking for refund (and they agreed). Bye

I warn you trying this setting. I tried this >>> Editing .XML file. I started getting severe force closes especially Google Frame Work Services. Even reverting did not help. Had to use my Nandroid Backup to go back.
4.3 is sucking so far for 64 GB External SD Card write support. Titanium Backup & Helium both apps can not do automatic scheduled Backups on External SD Card since 99% of the time they do not get Write Access. Only way to do an external SD Card backup is manually after rebooting the phone, even that is hit n miss.

I agree with you. 4.3 is still far from 64Gb SD Card support, and I know that editing this file can be dangerous, but I read that someone was able to restore his card and due to its cost was worth a try. During my tentative, this update didn't have effect (but at least I didn't get more troubles).

Same issue.
64GB SanDisk card from my Note 3 (search brought me here) became read only after 5 months.
I've ended up sending it under warranty back to SanDisk.
I'm glad I didn't loose anything as I've backed it up but still don't like the idea of returning something with a lot of my data and photos I can't delete.

may have found solution

I was having the very same problem. I finally went into the computer management, and was about to throw phone across room....when I tried to format one last time. This time I unchecked the quick format. It is taking longer, but seems to be working...I am keeping fingers crossed.
Full Format has finished and card is saved! Hope this helps anyone in the future.
