Hey guys
I have Samsung Galaxy S GT-i9003, and I am using the vold.fstab mod for swapping the internal Sd card for the external. I have every thing running fine. But I noticed a strange problem. When I open applications, it seems like the memory card gets mounted in read-only mode, as when I try to use any file explorer to remove files, it cannot delete until I either use root explorer with mounting as R/W mode, or rebooting the device. If so, things get fixed, but after some use, the problem recurs. Besides, I noticed that while the problem is active, the gallary opens empty with a message showing up "No SD card detected". Otherwise, and even with the problem is active, apps open normally and flawlessly, but unable to write files or delete them. Rebooting always fixes the problem.
Any idea why this is happening?
BTW, the card is very new and healthy, and opens perfectly with card reader on windows, and sends and receives files to and from the computer very fast, and it is 16 GB.
Thank you
I solved that problem after months of research... You see, the problem is corruption... The explanation is very very complicated so I am giving you the things you need to do to fix that read only problem...
(Should be done by steps)
1. Put your sdcard in a card reader (recommended) and use chkdsk /r (if you are using windows)... Or simply go to drive properties and go to error checking, check all the boxes and start scanning until finish... Put your card back to the phone... Check if the problem still persisit... If it still persist, do step 2...
2. Backup all files to your computer... Reboot your phone to recovery mode and use the format sdcard option in the mount and storage menu... Restore all data afterwards.. If it still persist, do step 3..
3. Believe it or not, some files in your sdcard are causing a data corruption (This was my issue).. The only fix for this is to find out what files are corrupted... Mostly, the directory that contains these files are from:
sdcard/Android/
sdcard/Gameloft/
sdcard/data/
sdcard/lost.dir/
Do step 2 first... When attempting to restore the files back to your sdcard, do not include this directories... This will more likely solve your problem...
4. Some tweaks such as sdcard speed tweak and other sdcard related tweaks in init.d folder is causing this problem... Try to boot your phone without them and see if it works....
Thank you very much.
I really have some gameloft games installed and believe it or not, the problem is almost always occurring when I open these games !!
I will try your solution and inform you of the results .
BTW, what if the problem is caused by the files of these games? And what if the problem recurred after restoring these files? Is there a permanent fix for that?
Thank you

It seems like it's SD card problem, although it's new!!
I was playing on a game installed on USB Storage, and all of a sudden the game became unresponsive. I then forced reboot the device, and when restarted, SD became unavailable!! I went to "SD and storage" settings and both SD card and USB storage give "Unavailable". Pressing on "Mount SD card" does not work! Formatting is not working!!
Any suggestions guys??

BTW, I remind you that I am using the vold.fstab mod, gingerbread version. I tried to install another SD from my friend's phone that is working fine in his AT&T Galaxy S i9000, but once done, it gives me "USB Storage damaged" !!!!!!!

Seems like I lost my SD card
It opens normally in Windows, and I could back it up. When I delete all files, it gives that they were deleted. But when I eject it and reinsert it, the files are not removed
Neither formatting nor chkdsk in Windows work
GParted gives "Unable to open /dev/... as read-write (file system read-only)"
Any suggestions??

do you mind to post a screen short by command mount in adb shell?
Actually, I took the memory card back to the reseller, and they changed it for another working one. I just dont know why would all of this happen! The card is new, but there were problems preceding its damage, like the aforementioned problem of read-only!!

It seems that I forgot to mention regarding a bad sdcard.. Some issues are appearing because your card is either damaged or is badly made... Glad to hear your problem solved...

Actually, during searching for a solution for my problem, some websites suggested the following:
1- if your card gives you that it is read only, try to use micro SD adapter, and put the lock half way between the locking position and the unlocking one, th en try to perform chkdsk, followed by formatting attempt.
2- if formatting has failed, try to use GParted (bootable live disk is available online and can be downloaded).
Your internal SD will subsequently be recovered once the external is recovered, or simply, put a new external SD of whatever size, and you will regain access to your internal SD, and thats supposing you are using vold.fstab mod
Please let us know of the results , hopefully it works with you

I was going to post this in the AOKP rom page but i figured it'd get seen more here and maybe its not even a problem related to the rom. I recently installed the AOKP rom located here http://forum.xda-developers.com/showthread.php?t=1831858. everything was great the first day then i started getting random reboots and losing my data. So I flashed a back up and still got the same problems. I lost my data yesterday, fixed that by manually changing the APN settings and everything was fine other than still getting random reboots. today I went to take a picture and it says "no external storage". I opened root explorer and I can access my EXTERNAL SD card but not the INTERNAL. I tried to mount in via the setting, storage menu and it wont mount. Also tried mounting in CWM recovery, no dice.
Is this a hardware problem or something software related? Anyway to get my stuff back or is it gone? I thought about trying to format it through recovery but how can I do that if it wont mount? Any help would be greatly appreciated.
I'm about to go through and install a "clean" copy of this ROM hopefully. Or I might try another ROM I know works like it should.
Installed a new Rom. Everything works perfect so far but still can't access my internal sd card. Any tricks how to get this back or do I need to just turn it in for warranty?

Warranty may be your best solution, you'll have to revert to stock using kies/odin which may on it's own fix your issue.
Are you also receiving the "Blank USB storage or has unsupported file system" error?
I have been battling this issue for a friend of mine (I own only the I9300) and I believe I have somewhat of a fix. It will allow you to use an external SD card.
If you can use / access the external SD card on your phone then disregard this message.
If you can't access any of the storage, including the external SD card try following this short tutorial I made:

Im still able to use my external sd card. I can read and write to it from both phone and pc.
Sent from my SGH-I727 using xda app-developers app
The internal SD card is essentially part of the motherboard. If it's corrupted, you have no choice but to warranty the phone out. Kishke's right in that restoring to stock might be your last, best chance.
It seems that my SD card is not writable when inserted. Is this true? I tried to create a new folder on it with root explorer (I am not rooted though) and it said that my device needs to be rooted in order to accomplish that task.
Any ideas?

Did you try something like es file explorer? I would try that.
That didn't work either. It says "operation failed".
I actually noticed that it wasn't working playing act raiser and it wasn't saving my position. Moving the ROM to internal storage worked. I then tried to create a folder.

Huh. Just tried a different SD card and that one worked. Weird.

I spoke too soon. After removing the sdcard that worked and putting it back in, it no longer is writeable.
Sent from my Nexus 7 using Tapatalk 2
It works again if I pull the card out, restart the shield and put the card back in. Perhaps something up with the mounting process?
It appears that once a card is mounted, if it is removed and re-inserted, it remounts as read only.

It looks like sdcard mounting is messed up. I can't get any of the sdcards i have tried to mount.
Did you go into settings and actually click unmount before removing the SD Card? Many linux systems (android is linux) will mount devices which werent safely removed in read only mode for some bizarre reason.
I tried that as well. It still doesn't work.

when you go to storage under settings, under sd card does it show total space for card. if not maybe you have to format it to NTFS first. thats what I had to do with my new card. also said to do so on shield guide

I did not read the destructions. The destructions have useful information? Where may i find these destructions? I assumed fat32 so that is what my sd is formatted to.

sorry i cant post link yet cause im new to forum. but go there, (shield.nvidia.com/user-guide/sd-card) user guide said to format it to NTFS

Still wont mount, but now i at least get the option to mount.

Yes, I formatted it to NTFS before I inserted it. It shows the total space and space available, it just doesn't allow anything to be written to it. I can take it out and put it in a PC and it works correctly. I also have another SD card that I tried and it worked for a few minutes, but I haven't been able to get it to keep working.

sorry I dont know what else to tell you, i first had the same problem like yall when I stuck in a brand new card. nothing I downloaded would go on to card. and it didnt show the amount of space left under the storage menu. Then i found out it need to be formated to NTFS. Once i did that everything started downloaded and showing up on card.

The only memory card I have gotten working (about 1 minute ago) is 512MB and formatted fat32
The card i want to us is a 16gb microsdhc formatted fat32 when this memory card is in my shield it knows it has a memory card but says it has no partitions on it.
I am running testdisk on the sd card and it found 9 partitoins. I will try and clean that up.
To be honest, I've never tried SD card support on the device. So I can't say one way or another. But I'll be looking at it soon enough since I got my first build of CWM for SHIELD waiting for me to debug in the other room once the kids go to bed.
I just tried two different 8GB class 10 transcend cards, an 8GB class 2 generic card and a 256mb sandisk card. I put each card in and copied a file from internal storage to it. Then I removed each of the cards without unmounting and put them back in and proceeded to copy a file to the card again. Every time it worked successfully. I do not even know what format they are in and didn't format them before testing. And, maybe the issue didn't show up because I didn't give it enough time. I am not sure.
Also, I know this is probably a really dumb question but the micro sd slot is spring loaded. You are pushing it in until you hear a good solid click right?
issues
Having issues of my own.
Bought a 64gb sandisk SDXC card for shield. It worked 100% fine in my SGS3 formated for exFat. But not in the shield...
It seems to work somewhat when formated for NTFS. But the file path is really messed up and 1/2 my apps cant see the SD card because of this. It something like (root/storage/sdcard1/....)
2 apps that are basically usless right now due to this are Power amp & FPse.
Android doesn't normally support either exFat or NTFS. The shield may include support for them but if I had a shield I would steer clear anyway and go with what android definitely trusts in FAT32.
Hopefully NVidia will do a firmware update to sort these problems though
I received my Note Pro (WiFi) on Wednesday.
It really is superb and I am loving it, however I have a really irritating problem.
When connecting to my PC and attempting to transfer content to the Micro SDCard (SanDisk 64gb - mainly video files) the connection frequently drops causing the transfer to fail. Sometimes it is fine for a file or two, sometimes it fails on the first file. The PC then cannot see any content on the card untl I reboot the Note Pro.
Any ideas?
Please note:
1) I have tried two other cards, another 64gb SanDisk and a 32gb Samsung but this happens with all transfers (suggesting its not the card)
2) All cards work fine in my Note 3 and Note 10.1 2014
3) Transfers to the internal memory are fast (on USB 3.0) and work fine (suggesting it is the Note Pro)
4) Transfers from my PC to my Note 3 and Note 10.1 2014 work fine (suggesting it is not the PC)
5) The problem occurs with both USB 2.0 and USB 3.0 transfers, and with various cables to any PC port
6) My MX Player Pro app cannot delete files from the SDCard but can see them
7) Some apps (e.g. My Drives) cannot see the SD Card but the stock apps can all see the content and delete/modify files
8) I have tried reformatting the cards both in the Note Pro and the PC but that makes no difference
9) I have used Kies 3 to re-install the USB drivers but this didn't cure the problem
As my primary use for the tablet is watching pre-downloaded video on my commute to work this is very frustrating.
It might be that this is a firmware problem that gets sorted as the device becomes more available and I am working round it atm.
Any help would be appreciated.

Are you able to check out logcat to see if it is spitting out any errors?
Logcat
I have repeated the process a few times but cannot see anything obvious in logcat. There are certainly no errors in the log immediately after the event.

I'm having a similar issue when transferring a 1.3g video file from my notepro storage to the micro sd card.... It starts to transfer the data and then fails.
It's like the sd card had been removed as when I look at the sd card using a file Explorer it is accessible but all info on the card isn't present. If I unmount the sd card I can't remount it, I have to manually remove the card and put it back in to see any info on the card!!!!
Definitely a faulty sd card reader or a bug in the firmware!!!

Just got off the phone to samsung support..... its definitely a problem with how 4.4 is implemented on the NotePro, even though the Samsung Support Guy did everything he could to blame my SD Card.
Hopefully a firmware update will fix it a little down the line.... so for the time being my micro sd card adapter is going to get a lot of use!!!!

Looking around the net and looking at Note 3 and Note 10.1 (2014) forums there have been lots of problems when people upgrade to 4.4 and aren't rooted.
It looks like the permissions are set to disable write access to the ext micro card, if your rooted it's is easy to change these, if your not it can't be changed.
Samsung will need to change these permissions if they see fit and release an update. I have sent an email to Samsung support advising them of the issue and also advising them how to fix it..... Just have to wait and see!!!

As a temporary workaround you should be able to transfer files to the sdcard using an external reader. I should be getting mine soon so I can test this out.
Is this an issue with all note pro 12.2s? just returned one and ordered another for this issue... Was able to transfer to main memory over WiFi then copy to SD card but transferring to the SD card over WiFi was a 50/50 chance if even that...
I was expecting a lot more reports once the tablet launched in the US but haven't seen too many so far.
It's a real pain but I can live with it. I'm waiting it out for firmware fix for now, but if that doesn't come then it's going back. There is time yet and I love the screen size too much to let it go...
Let us know how you get on with the replacement.

Same issue with replacement and replacement card... Can not transfer files using WiFi to SD card... Can transfer to device then copy to SD card, hook up usb cable and transfer to SD card or transfer through a card reader... hopefully Samsung will get on this quick like... lol ya that made me laugh too
Exactly the same problem here with mine (UK). Hopefully Samsung will hop on it asap. Glad I don't just have a duff Note. Thanks! :good:
Is this just a problem with the UK version? I think I read somewhere the US version was coming shipped with an update that the UK version would soon be getting?.. If it makes anyone feel better, my US model has no problems at all syncing to the external over wifi..
The only problem I did run into was the changes of writing to the external sd with 4.4 Normally I would just make a folder anywhere on the external and sync my comics to it in the past.. but now, I had to copy my reader app to the external and then make the folder within that one in order to copy my books to it..
It looks like this is a widespread issue caused by Android 4.4. Since Samsung is running KitKat on these out of the gate, it seems to be a pretty widespread issue. From https://plus.google.com/+TodLiebeck/posts/gjnmuaDM8sn:
KitKat will make your SD Card completely useless: per the Android API specification, apps can no longer write files to your SD card. And Samsung is following it.
This only applies to dual-storage devices, i.e., devices with a user-writable internal flash storage AND a removable SD card.
From http://source.android.com/devices/tech/storage/index.html:
"The WRITE_EXTERNAL_STORAGE permission must only grant write access to the primary external storage on a device. Apps must not be allowed to write to secondary external storage devices, except in their package-specific directories as allowed by synthesized permissions."
If your device has user-accessible internal flash storage, your SD Card is a "secondary external storage device".
What this means is that with KitKat, applications will no longer be able create, modify, or remove files and folders on your external SD card. As a for-instance, you can no longer use a file manager to copy files from your computer to the SD card over a network. This ability, which has existed since the beginning of Android, has been taken away.
The only stated reason for this removal of functionality is that, "Restricting writes in this way ensures the system can clean up files when applications are uninstalled." I do not pretend to understand this logic. Apps are still allowed to write in arbitrary directories on the primary storage (with the appropriate permission), but are denied the same access to external storage.
Samsung has implemented this feature with their KitKat OTA updates. Note3 users are now complaining that FX File Explorer can no longer write to their external SD cards. There are solutions to this problem for users with root access. Users without root access appear to be screwed.
I'm not quite certain how Google intends for you to place files on your SD card. Perhaps you have to use proprietary Google apps that contain permissions unavailable to the rest of the developer world. Perhaps you're supposed to put everything on the cloud and pay carrier data fees to get it there. Perhaps you're supposed to use some kind of WIRE to attach your WIRELESS device to your computer and have the computer do that work for you.
In my opinion this is a horrible misstep by Google and the Android Open Source Project. Functionality has been removed without reason, to the severe detriment of users and developers alike.
I apologize for not bringing this to everyone's attention when KitKat 4.4 was released, but it was not mentioned in the Android 4.4 changes document: http://developer.android.com/about/versions/android-4.4.html. It's only mentioned in the article on source.android.com. I was only made aware of its existence from user reports as a result of Samsung implementing this change in its KitKat OTA updates.

Now, there is a fix for this, but you need a rooted device.
Can it be that this is the culprit:
KitKat will make your SD Card completely useless:

It looks like this is a widespread issue caused by Android 4.4. Since Samsung is running KitKat on these out of the gate, it seems to be a pretty widespread issue. From https://plus.google.com/+TodLiebeck/posts/gjnmuaDM8sn:

Tried this on my GalaxyNote Pro, and the fix for the N9005 as described is working . Titanium backups and Appmonster backups are now stored on the ExtSDcard.

Hello All,
Since kitkat 4.4.2 was released on the Galaxy Note 3, many users were unable to write files to the External SD Card. Below is a simple fix for rooted users on the Galaxy Note 3 N9005 ( International Snapdragon Variant).
**Please be advised that I have only tested this on my personal N9005. However, you are free to test it on your own devices at your own risk!! **
1. Using a root-enabled file manager, navigate to /system/etc/permissions
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission...
4. Save the changes to the file.
5. Restart.
Attached is a copy of my platform.xml.

I have tested and can confirm following these directions to the letter on a rooted device, does solve the problem on the Samsung Galaxy Note Pro 12.2 - SM-P900. I'm now able to write & save to my Sandisk 64gb HS SD card without any problems at all!

Is not working for me. Lost ability to see my sd card and all apps where failing. ALOT!! Not exactly sure what the issue was. I had to reflash using odin twice to fix the issue. Also before reflashing it seems I lost the ability to write to either sd card. Internal or external.
Got it to work o the second try. Make sure the format is exactly the same when you add the new line or things go crazy

Use 64GB sd card(Fat32)to store photos and video, but it crushed once i plugged into the device. Photos not preview and video showing FILE CAN'T BE PLAYED. Is anyone experience this? I understand the KitKat is not writable on the SD card, but i'm not sure is storage not available as well. PLEASE HELP!!!!!!!!!
Try to reformat the card via your PC, fat32 and try again. If that doesn't work, try to reformat in EXfat

I'm not say that this is going to, or still is an issue, however, in MY OWN PERSONAL EXPERIENCE and from what i have read 6-10 months ago or more (maybe they have solved this issue by now i don't know) every time i formated an SD card Via PC it was horrible and the format destroyed the MicroSD card for use with any android device and then even my computer and they where all BRAND NEW. I think it has something to do with the formatting process of the SD cards and the phone because my 32GB cant be recognized anymore by any device but i can format it all day long on my PC and my androids will not see it... I even tried to format it BACK to what android uses to format the cards on ADB and NOTHING ever worked again. MY SUGGESTION IF YOUR USING IT FOR YOUR PHONE DON'T FORMAT YOUR CARD VIA PC. Flash memory is also has a write life. UNLIKE A HDD that you can erase and move files around constantly the more you erase and move files on your SD card the quicker you are going to see the integrity of your card degrade because FLASH Memory can not handle the constant moving and erasing over and over again. so if you want to ave the life of your flash memory and don't want it tos burn out because i guarantee it will, just be mindful of how many times you move and erase. just a tip. if im wrong someone correct me. good luck!
Try to reformat it on the tablet, not the PC. (Settings --> Storage --> Format MicroSD)
