(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?

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...

It says the permissions cannot be changed because the file system is read only

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.

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.

Need help ASAP

A little while back I posted a thread asking the following.
"Just recently rooted my friend's GN2, I transfered the files to the SD card and went into CWM recovery. I'm having 2 issues.
1: The phone says there's not enough room to make a backup when there clearly is. I have about 2 gigs on the internal, but but it either says I have 3mb of free space or 0.
2: I click 'install from SD' and the only file it sees is "-clockworkmod/ ".
What am I doing wrong? I personally have an S2 and it's very similar but these two things are preventing me from flashing any rom"
The only person to respond recommended I format the sd card so I did so. However the phone still did not recognize any files in the sd card so I couldn't flash any rom. Upon startup it began boot looping and the phone is no longer activated? It can't make calls or send texts and reboots every minute upon ' failed activation'. The phone currently is useless. I'm not new to flashing roms I've been doing it for years but this is the first time I'm stumped thanks to some bad advice (not blaming that person) and it's not even my phone. Luckily I just got an htc one and I could give my friend the my s2 until the problem is fixed...any ideas how to fix it? Or unroot at least to bring in for repair?

Try using twrp instead. Sorry I couldny be more help. But I have never used cwm on this phone since I got it. Only twrp. You can find it in original dev section.

Yes use twrp. Find the latest version and flash it in clockwork. I havent used cwm since my og evo lol.

Maybe I'm old school but I'm a long time flasher and I've always just been more comfortable with cwm. But I'm not so sure it's a kernel issue?
Edit: and the issue is that I can't flash anything because I can't store anything on the sd card. I'm thinking of odining to a stock build?
Sent from my HTCONE using xda app-developers app

The only thing I can suggest is doing a quick format on the SD card to FAT32, especially if the card is a 64 GB card. Also, some Sandisk 64 GB cards were bad from the factory, so check that too. Finally, if all else fails, try breaking the phone even more to the point it won't even boot and get a replacement.

Don't come up with one. Just take it in and show them. Before you take it in, if you can, try to reset the flash counter. If they can check that and see it isn't correct, you're in trouble. If it's reset or it can't be checked, then take it in.

seriously, ODIN something. stock it.
if you're not really familiar with samsung stuff, do a bit of reading. perhaps a pit file might be needed. garwynn and sextape have some good threads on this.

Thanks guys. I'll try some things today and check back

Ok...what files did you transfer to the sd card? Was it the internal or external? Even 2 gigs on the internal for a backup may not be enough. I have a backup that is just over 3 gigs. As far as formatting your external sd what did you do ? Fat32? Personally TWRP is the way to go. Try to format fat 32, download a stock rooted TW rom and put on external sd, also dl TWRP recovery to external sd. Boot into cwm recovery and try to flash twrp. If that works out pull battery put back in volume up+home+power. Hopefully that gets you to twrp, if so go to wipe then factory reset. If you click on advanced it will let you wipe system which couldn't hurt. After that, back arrow on bottom of screen to twrp home screen. Click install...choose external then locate where rom is...hopefully on root of external and see if that helps.
Oh and was the phone activated prior to flashing?

Please do the following:
01). Format the SD card to FAT32 (NOT EXFAT OR NTFS) on ANOTHER computer and do NOT use the built in windows format options. Use a third party tool like guiformat.exe and do NOT USE QUICK FORMAT. (With my current sd card, windows format failed, guiformat.exe partially failed(and by failed I mean formatted fine but caused problems being seen) but I installed and used eausus partition master to regular format it to fat32 and followed the next few steps and its been working fine ever since.
02). Immediately after formatting the SD card slow format to fat32 in easus partition master create a text file on the sd card in its root directory (I've had an issue before where my SD card would not be seen or writable by certain devices if the root directory was 100% empty), before you copy any further files insert the SD card into the phone and use your recovery kernel(CWM/TWRP) to navigate to the root directory of the sd card and insure that you can in fact see the text file you created, POWER OFF THE PHONE(or alternatively unmount it in android terminal if possible) before removing or inserting the SD card(also always eject from the PC before removing, do not just rip it out off the usb slot/card reader), insert the SD card back into your PC/card reader and copy TWRP to the sd card.
03). Boot back into your current recovery and Install TWRP(if it's not already) you may prefer CWM but TWRP just causes people a lot less bugs in general.
04). Verify in the backup section of TRWP that you have explicitly selected external storage as the backup location and given the backup a name, as internal storage is selected by default, and you very well may not have enough free internal storage for the backup, regardless of whatever reasons you think you should.
05). Its probably a good idea to turn off md5 verification of the backup, I do this every time, the one time I did try to verify a backup with an md5 checksum it failed, I unchecked this option backed up restored to it and all was fine(and still is), also a good idea to uncheck md5 when installing roms/kernels/apk's as most don't have md5.
05). If the above does not work you probably have a bad SD card, try another and post back here.

There is
no external sd card in the phone. Just a 16g internal, and I've wiped pretty much everything so there shouldn't be a problem with room. I'll go out and buy an external and attempt to flash something.

Can't thank you enough for the post, I appreciate it. Parts if it are a little over my head (most of it actually) but I'll try and manage aha. I'm a little confused on step 1 in particular, how do I format the sd card to a computer? Is there a separate program I need that manages the phones memory temporarily through an external hard drive or...

Il if you are treating the phone plugged into a computer via USB the same way you would treat an external microsd card you are making a huge mistske/misconcepyipn ..
I am at work right now so I can't help further but at this point you need to.find and follow the instructions to restore the phone back.to its stock state and start from.fresh.

Thanks. The problem is that the phone boot loops so fast that I can't stick anything on the internal. And the one time it was on long enough to, the phone still reads that there's no files there. It's why I'm in this mess in the first place, I don't know why it's not recognizing any files

If you wiped everything then you might have wiped the partitions by accident. Get an ext sd card put flashable rom on that then boot into your custom recovery and try flashing the ROM through that

That seems like the best thing...won't the phone still rely on the internal sd card though and keep bootlooping?

Odining back to stock is prooobably your best bet. No need to go through repair fees or restocking fees etc. When you can fix it in house.

It should not rely on the internal. Download mode is deep down in the bootloader. If you borked that then jtag or sending it to samsung/asurion is the only option.

Try a stock rooted rom and see if it works. Because it should at least give you the boot.img in the rom so you might be able to get past the boot screen. Hopefully it will re partition your phone. Im not for sure but its worth a shot.

External SD card write issue

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.
Sent from my AOKP GS4

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.

[Q] Running out of Space, Symlinks and Installing Apps to SDcard

Due to size limitations (GPads only coming in 16gb varieties) I am beginning to run low on space on my Gpad (v500 running cm11). However I have a 64gb microSD card and I would like to use this as much as I can to conserve space on the internal memory.
There are a few ways to solve this but I not fully know how to do this.
Firstly, is it possible install apps to microSD card? If so, how? I know some devices support this and some do not. My phone for example does not but I have heard that some people have had success with this.
Next, there are some rather large folders on my internal storage that I would like move to my sdcard however the apps that use those folder can only read them where they are currently located (cmupdates, ebooks, etc).
I read about symlinks and managed to make a few but the only place I was able to make a symlink was to /data/media/0. But the changes to that do not show up the apps which I believe read either /sdcard or /storage/emulated/0. And for my SDcard I can get to it either in /mnt/media/sdcard1 or through /storage/sdcard1.
I tried and succeeded in making a link between /mnt/media/sdcard1/eBooks and /data/media/0/eBooks however the link does not show up in /sdcard or /storage/emulated/0 and it does not show up in the apps, leading me to believe that is where the apps read the sdcard from.
If anyone can answer the above two questions or give any other suggestions for maximizing available space on my internal card please let me know.
Thank you!

I think most of your issues could be resolved with Link2SD (under 10 posts, can't post a link to Google Play).

You can also use an app called Foldermount. It's only $.99 ( if I recall correctly) for the unlocked version. This allows you to move any folder to SD card. I like it as it guides you thru the way and will move the data for you as well. Latest version has been updated to allow apps from play store to install properly. Well worth the $1 price.

Thanks guys! Looks like using these two combined I can get exactly what I wanted. I'll use link2SD to put apps on the SD card and Foldermount to move the other folders I want moved.
Thanks again!

Can you let me know if this works for you? I can't get mine to read or write my SD card at all! I can't even move a picture from my Box cloud account to the SD card. Are you experiencing this? Or did I get a bad unit?

These solutions did work for me, I am still tweaking to get it the way I like it especially since every time I update my Rom Link2SD has to generate new scripts. I can ready and write to the SD card just fine and I could before I started using this as well. I am not sure why you aren't able to write to your sd card. Could it be a bad SD card? Try plugging it into your computer.

I've tried 2 different SD cards both of which I can move files to and from on my computer. So I know it's not the card. I'm thinking maybe I should exchange it out for another day one...

Probably... That sounds like a device issue not card.

How are the cards formatted?
The ROM you are using may not support the format.

I'm not sure I just put the card in my computer and clicked format SD card. I'm not rooted or running any special ROM, it's completely stock out've the box.

Well, if you did it from your PC, it may be formatted NTFS, and you need them formatted FAT 32. Get it here; http://www.partitionwizard.com/free-partition-manager.html Not only allows formatting almost any format xFAT, Fat32, NTFS, etc.. and you can partition them also which is not supported by Windows, but IS supported by most Android ROMs. I doubt there is anything wrong with your device.

Thanks for the tip, this makes me feel a little better about my purchase, I'll give it a try. I'm also thinking of buying a 64gb San Disk card and hopefully it will just work with a brand new one.

I have been trying to fix the issue with Rom updates and link2sd. You have to provide the Rom (in my case cyanogenmod) a backup script so it can back up the files. I am planning on figuring it out at some point but if you get it before I do would you mind posting your script? Thanks!

So a follow up with this, I was able to get a script working. I don't know if this feature is unique to cyanogenmod or not but any script in /system/addon.d will execute itself during a rom install and be restored automatically if it was wiped. So using 50-cm.sh as an example I made a script called 11-link2sd.sh to perform the backup of the mount script for link2sd which is located in /system/etc/init.d/11link2sd.
I then had insert this script and my mount script into a cyanogenmod update and flash it in. But after that I tried flashing an update of cm11 to test it and it worked! Attached is my script which should also work for anyone who is able to flash it into their /system/addon.d folder.

SD Card Issues

Hello All,
Two weeks ago I bought a new Samsung MicroSDHC Pro 64GB Class 10. Kinda from the beginning it wasn't working how it should.. I formated it EXT4, exFat and FAT32 but all give the same problem.
For example; I copy a flashable zip on my external sd card, copies just find, but as soon as I try to flash from the external sd card I keep getting an error and the flash failed, almost instantly. If I copy and flash the same file to my internal sd card, it works just fine and no problems what so ever.
I tried formatting it through Sense, GPe and even a USB card reader.. all give me the same issues. I can even make a titanium backup and it seems to work. Tho, as soon as I try to restore from it, it won't find the files from the backup..but when I check the external sd card on my pc (phone connect to pc by htc usb cable) the files are there and it seems the correct size. But when I want to try a batch restore in titanium backup, and I look the phone for backup folders, it finds the foder.. but when I actualy wanna start the batch recovery, it only sees 1/2/3 apps to restore, even tho there are over 70 apps to restore.
I'm at a loss at the moment, I feel like I've tried everything and nothing seemed to work. This is what the error looks like when trying to flash from external sd card:
E:Unable to open zip file.
Error flashing zip '/external_sd/blablabla/blablabla.zip'
Updating partition details
Hope anyone could help me with the issue.
Thanks in advance<3

I've seen in the past that 64gb cards have issues with formatting unless formatted in windows as Fat32 - mine did
As soon as I did that it worked.

Have you checked it to make sure it's not fake? Where did you buy it from & what is the formatted capacity? Should be like 59gbs and change

Got it from a dutch website, through a person, not a company.. it had all legit packages etc, but how can I check to be 100% sure that it's real?
My computer shows it has 62,4GB total capacity.. reading it from card reader. Sounds wrong?

Deffo wrong. Sounds like a fake. Capacity is 64gb. Available is obviously lower after formatting. Legit packages mean nothing - take a look here

I would return it asap
