I flashed the root66_ATT_I747UCDLK3 image the other night and performed a full factory reset in stock recovery. The 16GB external SD card I've been using for a couple weeks was working fine with TiBu Pro 5.7.2 on multiple ROMs (all JB-based, but on top of ICS firmware of course). Now, with the JB firmware underneath, TiBu appears to "lose" write access to /storage/extSdCard after a couple operations. I was able to restore a handful of APKs from my last backup (FrostyJB v10.1 TMO, with edited build.props), and then I had to force-stop the restore because it hung. When I went back to TiBu and checked the Backup Directory location in Prefs, it said it did not have write access to the directory. I have to unmount and remount the card in order to get the rest of the system to recognize it as writeable again after this (or reboot).
Other applications seem to work just fine with the extSdCard. I'm able to save photos to it, copy files via AFT (I have a Mac), and download via the browser to /storage/extSdCard/Download. Only TiBu seems to have problems. TiBu is able to read/write to the internal SD card with no problems, and I've been able to freeze/unfreeze applications and restore backups of call logs and messages (saved to Dropbox, not the external SD card) without issue, so I don't think it's a problem with TiBu's root permissions.
Anyone else seeing this?
Short of formatting the card with the JB image and testing again, does anyone have any suggestions?
Crap, looks like other apps are starting to have problems with the external SD card. I took it out and ran several copy/delete cycles via an SD card reader on my Mac without issue, so I don't think it's the card itself. I also had no issues with the card using the ICS firmware (even with JB ROMs on top of it).
I've edited the title of the thread. Is anyone have trouble with an external SD card in JB? I've tried formatting it, and that didn't appear to fix the issues.
Some more info. I found an old Class 4 2GB card laying around and TiBu and other apps seem to be able to read/write to it just fine (so far). The 16GB Class 10 card I was using, despite seeming to be fine according to my computer, doesn't work reliably with the phone since I updated to JB. Not sure if the speed of the card has anything to do with this, but is anyone else having trouble with Class 10 cards? If so, how big is your card?
One last update--I reformatted the 16GB Class 10 card using exFAT instead of FAT32. It seems to be happy with it so far. I was able to complete a couple of backups to it with TiBu. I will test it again periodically throughout the evening and report back.
Also, if it fails again later, I will remount the 2GB Class 4 card and do some periodic testing on that to see if it's a situation where things work immediately after mount, but then start failing later. If that's the case, does anyone have any ideas of how to start troubleshooting? Would logcat capture a filesystem being remounted read-only?
I had the same issue but I ended up flashing CWM then TWRP. Now TWRP can see my external and internal.

Thanks for the feedback, but I'm not talking about a recovery having problems with the external SD card. This is applications on the ROM itself.
So far tonight I've run several TiBu forced redo backups and taken several pictures, and they've all worked properly to the external SD card. The computer format to exFAT seems to have helped. I won't call the issue fixed until it works properly for a few days.

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?

Try downloading root explorer and mounting it as r/w

do you use an adapter to connect it to your pc?
also, i had a sandisk usb flash drive. 2 of my coworkers had a flash drive and micro sd go out in december and january. coincidence? perhaps...

How was this solved?
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.
I'm currently running a rooted GPE G pad with stock 4.4.2 installed and am having an issue writing to the external SD card in both titanium backup and folder mount. In Tibu it says I don't have write permissions when trying to change the backup location to /storage/sdcard1 and folder mount gives me an error as well when trying to write to the same location. Is there some option in 4.4.2 preventing me from writing here or am just doing something completely wrong? I used the same sd card in my rooted Galaxy S4 for both these apps and haven't had any problems.

I had a very similar issue on the stock 4.2.2 (non-gpe version). Some games were not updating, error 492 if I recall. I could not delete or remove the folder, and certain folders were not allowing me to write to them. I chalked it up to the LG OS just causing damage to the SD card - I formatted it, installed CM11, and haven't had the issue since. I was able to put the MicroSD in the PC and delete the folder/files, but the folder would still appear (reappear/get re-made) when put in the tablet, as it would then show up on the PC.
Not sure what caused it, but I was under the impression it was the stock firmware. Evidently not.
Posted this in another thread, but figured I'd also post here for reference...
I had the same problem; couldn't write, etc although from a PC or installing the same SDCARD in another device worked fine.... called Google Support; no help by the way and after searching/reading for a while determined the problem.
This link explains how to fix... basically Android is not accessing the proper "name" of the external card and you just need to add one line to fix permissions.

Worked perfectly, thanks! I would likely have looked into returning it if I couldn't figure out how to fix that.

Just tried this on Stock LG Rom (V500) and unfortunately it did not resolve my issue updating apps that I have moved to external SD card via Foldermount. I can successfully run apps and write to external SD via titanium backup just can't update apps via play store. Foldermount developer blames LG and is already working to correct in his next version. Was hoping this was the solution. Guess will have to wait for update from dev.

First time I had a SD card get fried on me. Sandisk 64GB SD fails with write protect. Cannot even format on PC.
Could it be the G Pad is frying cards?
Hmm, not sure it's the G Pad. I have also had issues with Sandisk 64GB cards but in Galaxy Tab. I do not think the Sandisk are as reliable as say the Samsung cards. I think this is one of the reasons you can find them so cheap vs. other brands. Picked up 2 more for $34 each on Black Friday. In any case, you may be able to resurrect by using the MiniTool Partition Wizard. I had a card that I was able to fix by deleting all the partitions and recreating. Give it a whirl you have nothing to lose. The desktop tool is free.

I also had issues with Sandisk Ultra 64GB card, works fine with smaller cards. Kept saying card dismounted unexpectedly and Titanium would fail many times during a backup because. I CAN do a nand backup no problem in recovery and works fine in PC so some firmware issue with either 64 GB cards in general or just Sandisk? Same issue only worse if use a custom rom. Was gonna return my pad but once tested other cards realised some 64GB/Sandisk compatibility issue.... I can also recommend mini tool partition wizard

When you say you can't edit the file even after mounting as r/w, what error do you get? Basically, until you edit the file I think you'll continue having the problem.

Check SuperSU to ensure the app you're using has been given root access. If you can't edit the file, sounds like you don't have proper permissions.

Give this app a try, I've encountered various problems with different versions of the apps you've mentioned and never had an issue with this one. After install, add the root add-on and you should be good to go.

Hi,
I've only had Nexus phones and tablets before and have never had external SD card support. I'm on the stock LG G Pad right now (i.e. not the GPE). I tried to move folders to the external SD card using ASTRO, thinking that this would move my synced rdio and google magazine files to the external SD, but the apps don't seem to read the files anymore.
Is there a guide on how to get files to recognize that there's an SD card and an external SD card? Is my best bet to root and use TiBu?
THANKS!
Noob to SD

There's an app called folder mount which will move folders to the external SD card and link them such that the app will think the folder is in the same location and still work just fine. I've used it on my galaxy s4 without problems, however you do need to be rooted to use it. My problem is I'm on a rooted g pad and can't seem to get it to work. If you do root and it works, please report back, I'm not sure if I have a defective device.

Hey Abinash, thanks for the fix! It did the trick for stock marshmallow 6.0 and got my Z5p to be able to use the micro sd for app storage (just to "see" the already installed apps though). It made the phone work again as before the upgrade all movable apps (90%) were on the micro sd. SONY should not drop support for a device that was sold (and bought) because of micro sd support. This is not a way to say thanks to valued customers.
It doesn't work!!!!
