sd read only problem

Hi Im currently running wildpuzzle 0.7 and have an issue where the sd card becomes read only. un mount mount do not help, app can not have write access like camera for instance. Under windows file permissions appear ok.
Any clues?
Regards.
Problem resolved by connecting USB, using windows to check drive errors on card.
Thanks.
I would still love to know what may have caused it..........

dont think so pal, happened to me with stock card from phone :/

True, happened to me as well, and, only formatting the SD solved it. This happened to me using the stock card.
This happened when I was playing around with A2SD, and had created an EXT partition using ROM Manager. It worked well for a fe whours, then these errors started creeping up and I had to format it. Could be something wrong there....

SD card won't format

Sup guys. I don't know if this is the right place to post this. But here I go. My 32gb San Disk micro SD card was working fine on my gs3 until I got my s4 and now it seems to be write protected. I can't delete or add anything onto the card. It worked fine on the s3 though. So I Googled a little about this and came across a piece of software, which I downloaded and made use of. But the tool I used to supposedly fix the card actually made it worse. Now the phone can't read it, nor can the PC explore its files (but can detect the device), its like a non allocated partition that just needs formatting. But I have tried windows format utility, SD card formatter, HD low level formatter, and HP USB disk utility software and all of them without success. Please help me as I don't know what else to do.

use cwm recovery to format sdcard. u may need to root ur ph for dat

Yes the galaxy s4 does seam to have issues with sdcards, I myself had corrupt sdcard twice for no apparent reason. Your sdcard will now be in RAW file system and from experience very hard to recover, I've tried dozens of recovery windows apps to fix the partition without success (maybe just didn't try the right app) you can however recover SOME datas on the sdcard but there is no guarrentee how much or what you can successfully recover.
The moral of this story is to ALWAYS backup your data.

Hi, pop it in a camera, if it detects it you are lucky, format it there and you're all set. Unfortunately you will lose all the data

My camera uses SD cards I think, not micro. But I'll check
Sent from my Nexus 7 using xda app-developers app

just find an adapter from somewhere, usually one is supplied with the card

I tried clockwork mod recovery with no avail. I have little faith that a camera format tool would work, so I'm not even gonna bother to find a microsd adapter. Sigh. Any other suggestions please? I'm almost giving up

new card?

Yes, that's unfortunately my last resort. I was hoping it didn't have to get to that point though, cause where I live, a 32gb micro SD card is expensive as ****. But oh well. Thank you guys for trying.
Sent from my Nexus 7 using xda app-developers app

Why not just get a card reader and use a PC and partition minitools?
To get your SD card back You may even need to do a LOW LEVEL format. This is very different from a standard format.
Use Google and get a freeware version of a low level format software then repartition USB/flash drive then normal fat32 format.

[Q] Move Apps to EXT SD Card

Guys, I'm trying to move my games to my External SD card since I've got only 1gb left of my internal, but when I try to do it just from the Application Manager inside Settings, it only moves a few megabytes (X-Com Enemy Unknown has 3.7gb and moved to SD 60mb of it, awesome...)
I'm rooted, using X-Note 13, knox tripped 2 minutes after getting inside the house with the phone, I don't care about warranty or stuff, just... Could someone provide a fix, please? Tried App2SD, Link2SD and other apps like this, but it seems all they do is just move provide me with a shortcut to the same Application Manager from Settings that does the same useless thing. I didn't get a 64gb sd card to move 60mb out of 3.7gb from a game, seriously...

I think it depends on the programing of the game what can be moved and what not. Some programs can't be moved at all, but most of the big games I have, large portions of the data was moved to SD card during the install all by itself. If you just purchased the card, maybe reinstalling the game from start would give you better results, if that was an option? Also it seems to me you're using close to 25 GB of internal storage but you only mention one game, surely you must have many other large programs installed, what about them? There are some programs that can fool the system into "thinking" your external SD card is internal memory and your internal memory becomes external, but I don't have details ATM, also this could create problems if your SD card went bad.
And maybe you should take a hard look and see if you really need all those programs? If I didn't keep the tabs and clean all the junk, delete less frequently used programs etc. on regular basis, 96GB of memory wouldn't be enough either LOL.

I mentioned just one game as an example. I have quite a lot of space-hungry games, such as Bard's Tale, Modern Combat 4, Gangstar 4, Amazing SpiderMan2, etc...a total of around 40 games, mostly large games, and I have basically moved everything I could from Application Manager, yet it moved very very very little out of them. I tried deleting and reinstalling them, formatting my sd card, reflashing the rom from scratch with fresh sd, basically same thing every time. I got this phone to be able to have a mobile console with me that can also receive calls (boring job, games on phone help a lot), and now my sd seems so pointless
Internal Memory 26.3gb - 1.2gb free
Ext SD Card 59.0gb - 42.6gb free

bump, please?

The only app that worked for me is FolderMount [ROOT].

RinaldiMe, thanks a lot man, I just bought that app, testing it now, but from it's description, it should do exactly what I hope . It requires individual move of each app and folder, but it does the trick, thank you so very much
Will come back with replies as soon as I move 5-10 apps and test it out more
L.E.: Nope, bought the app, not just the free version, moved some files, still didn't work, apps just thought they didn't have their files and wanted to redownload...
Back to square one

I'm assuming your on kk bootloader and dunno if Mattiadjs int2extsd mod will work on 4.4, but I've been using his script meant for JB 4.3 that switches where the huge data and obb files are stored to your extsd instead of internal storage.
Try checking the galaxy s4 thread for the kk mod, I'll try looking too and post a link for ya. I know what your going thru as I have over 500+ apps/games and needed the 128gb SanDisk to store all my obb/data files along with pics and mp3 media.
Here's the link to the kk int2extsd mod

Any luck with that link I sent you, it's really easy to use as you just flash it in recovery. Your rom and kernel need to support init.d and it only works on TouchWiz roms.

Restoring a backup now, hoping it'll work. Basically it still saw my internal sd as internal sd, but it didn't see my card properly anymore (and yes i did check the exfat or fat32 version to use)

Are you tried App2sd?

Read op instructions. You have to put the same name folder both internal and external. Example: titanium backup. Both of internal and external must have the same name and caption.
Put all the titanium backup data in external titanium backup folder.
Leave titanium backup folder in internal empty.
Run the app, and select the correct path.

Any luck? this seems to be a generic android problem. can't believe no one figured out a solution yet. tried link2SD but it doesn't seem to see the full game size... detects something like 50 mb offf a 3 gb game...

assume u r note r rooted...install Xposed installer, then download a module obb on sd , enable it at the modules after downloading and installing, reboot and them move any game obb data from the note internal memory to the SD after creating folder Andriod/obb at sd

[Q] Phone Write Protecting External SD Card

Let me start off I'm running NAE Stock Rooted with SD Card Fix and HotSpot Mod. Recently my phone has been write protecting all my sd cards, (Sandisk Ultra 64gb, Samsung 32gb, and Sandisk Ultra 32gb) I put into my phone. It's getting a bit annoying now that I can't transfer any files to my external card. I try to formatting all the cards on the computer its saying its write protected. Does anyone know what causing the phone to write protect the sd cards and is there way to fix this problem?

Try folder mount from.the play store.

Thanks I'll see if this works and sticks. So far it let's me delete files and hope they don't come back . Before it would let me delete them then 10 minutes later they back.

It went back to write protection, it work for a few minutes the files come back after I delete them. Then files I did add would write then disappear a few minutes later. Anything else I can try?

Sounds like your SD card is no good. I had the same thing happen to me this weekend. I contacted Sandisk and mailed my card back to them yesterday for a replacement. I have only had mine since March. If you will go to their website their is a forum that discusses it and a place you can report it. Let me know if you have any problems.
Just curious what recovery were you running? I think you said you were stock rooted but no custom rom.

Its not just one SD card it's 3 sd cards that are getting write protected when I put them into my phone. My Sandisk ones I'll contact them about that and let them know the situation I'm having. For my Samsung one I don't know what to on that one. I'm running Philz Recovery on my phone.

Gallery photos broken, apps not found - SD failing?

Dear all,
I have a N9005 (eu) with 4.4.2 stock. Never rooted.
Since a couple of weeks, I notice a strange behavior. Quite often I find broken thumbnails in the stock Gallery app, sometimes the actual photos I have take are not visible.
At the same time, it happens that I download and install an app and it won't run, giving me an error in com.appnamewhatever. After a restart, I still see the link to the app on the home, but as I click it says app not installed. After I reinstall I can often run it np.
It gives me the feeling that the internal SD Card is dying. Is that possible? Can I run some tools/fixes to prevent or check it? (with no root required)
Thanks.

1. Take a look if your photos and pics are in SDCard.
2. Take a look if you have the apps installed in your SDCard too (Aplication manager -> SD Card -> App marked to move to SDCard)
3. You will have to take off the SDCard and try making photos and installing new apps (change your SDCard for other new if this go ok)
Tell me what result do you have in your tests :highfive:

Man, you are right. I had not moved any app intentionally to the external SD Card so I did not think that would be the case. But that's what happened, the failing apps were on the external SD and so are the photos. It's a SanDisk Class 10 64 Gb.
So no way out other than substituting it?

1. Take a look for what you can recover of your SDCard and copy it to your pc.
2. Format the card in the phone for last option.
3. Try again to put photos/apps there.
4. Good luck :highfive:

The corrupted photo's on the SDcard are a problem directly related to KitKat's increased security. It affects all KitKat devices. Any photo's on the SD randomly corrupt over time. The only solution is to put them on the internal memory.
The apps are a new one though. I've had apps suddenly become semi-uninstalled because I was dumb enough to mess with the Android_secure folder, but not with the errors after install.

Jeez that's crazy. I triedo to run a chkdsk on the card from windows (in a SD reader) and it got me a gazillion errors.
So now I proceeded to salvage what I can. I will try to format it (in the phone? in windows? still not sure about it) and see what happens.
Luckily I was able to salvage 99% of the photos.
I just remembered that I did something very unortodox, more or less at the same time problems started: I removed the SD Card with the phone still on. Yes, you can barely do it without removing the battery... I though "let's see if something bad happens". Maybe it started to corrupt the FAT or similar.
Anyway, please feel fee to point me to a thread or good article on this, I find information very scattered. Is there any advantage t oformat it in FAT32, NTFS or exFAT (assuming I can even choose)?
Thanks

I find it fairly easy to do. It's also perfectly fine, as long as you unmount it first in settings.

Fat32 is the common format IT doesn't allow for filesizes over 3.9GB, so if you intend to use t for films, use exFAT.
NTFS can't be read without root. Don't use it.
exFAT is practically the same as FAT32, except that it allows for larger filesizes.

Thanks for the infos. At that time I obviously did it without unmounting it first (no fun in life without some screw-ups). Regarding the formatting, I seem to be unable to do it from the phone at the moment.
It unmounts it, says checking it. But doesn't format it. Trying from windows now...

Here are some updates.
Formatting in either windows (stock function) and phone was a no-go.
However, I dowloaded and installed SD Association Formatter:
https://www.sdcard.org/downloads/formatter_4/
and that did the trick. Now the SD Card is finally empy.
Also I strongly suggest using this tool instead of windows proprietary, because it's simply much much faster.
I will try and load it back with the stuff I had before, including pics, and see if I get the corrupted data again.
A difference is now that the chkdsk tool from windows says that no errors are found, unlike before. Let's see how it goes.

Final update to close thread:
The SD Card, a SanDisk UHS Class 10 SDXC, 64 Gb, had been declared dead.
It was possible to write data on in with seemingly no errors (from chkdsk) but all the data turned out to be simply corrupted.
Will send for replacement.
I have seen many comments on this card failing, so I would not recommend it. However, I think that this case it was not KitKat's fault.
Thanks for the inputs.

Do not blame the card yet
I am having the same issue with the same card, but it is limited to Note 3(N900).
Every now and then it becomes inaccesible, the photos appear broken, music player stops etc. It is not related to use of any particular app. When it happens, the card is still visible in Settings/Storage, just no app including mounting has access to it. What helps, is the old reboot fix
Happened on official KK, as well on LP. Device is stock unrooted N900.
The card is working without any problems in Note 1,even in Galaxy duos, and there are no issues writing/reading in windows nor linux. Something tells me that hardware is to blame.
