Read-only sd card

Hi guys ,
I've been experiencing a quite frustrating problem for a while and I can't find any way out of it...
After some time my Magic 32B is turned on the sd card (4gb class 6) becomes read-only and none of my apps can access and write on it :
- Google listen return a I/0 error and stops streaming or downloading
- Camera won't work as it asks for an sd to be inserted
- Astro can access the sd but I cannot delete/move/rename any files...
If I reboot everything goes back to a normal status...but it's just for a while..
I tried fixing permissions..but it didn't help...
Any suggestion other than wipe/reformat...? I would like to avoid that...

[Q] Media not discoverd on SD card

So ive been I having the problem for a few days. It was all good just a week ago. Then suddenly my music player and the gallery containg my photos were unable to find the media on the sd card. But I can play or view the media by manually looking thru file explorer. When it first started to happen i could power cycle my phone and it would go back normal. Does anyone know how to solve this problem with out either getting a new sd card or reformating. Its been sometime since i installed the android nand and dont have the patients to install it again....

I suspect the SD card, if you have a card reader, remove the sd card (remove the battery first of course) and then copy/past all your stuff from each partition to the computer.
Download EASEUS free version and note the partition types and sizes then delet all partitions format and readd the partitions and their contents
If it was me I would just delete all partitions after saving my important photos/music then reformat.
Task 29 and reinstall the rom, only takes a few minutes, if you have done it once or twice already
Then copy the stuff back

Thanks bruh! I thank ima do that. Or I just found my wife's old memory card. Ill just swap it out she wouldn't know the difference... but definitely going try your way first...

Weird suggestion you don't have a 64 gb card in the phone do you ?
On the s3 forum some users were getting the custom warning when they had a 64gb card in. They v removed it and rebooted Ashes the warning went back to normal

Same problem
I had the same exact problem. When I rebooted my phone it showed an unlocked symbol under Samsung so I checked the status and it said custom. I have a 64gb card in it so after I read this thread I opened the back pulled the card, and then the battery. I then put the battery back in and rebooted the phone without the sd card in it. The phone showed the unlocked symbol again but when I checked the status it showed official. So I re installed the sd card and rebooted the phone. This time there was no unlocked symbol and when I checked the status it showed offical. Thanks for you help guys.

is there any more permanent solution to this problem?
I have stock rom, never made any mods, even the memory card itself is samsung branded, so it seems a bit crazy that i have to keep removing the card and battery (which is probably not good for the health of either, or the phone itself) just to get the official samsung firmware to recognise that it's never been modified in any way. i've not even so much as rooted it.

Thanx. Been bugging me for months, sometimes ok, sometimes not, Samsung tech support were useless. Because of continual media checking, with phone actually heating up! (150,000+ files, card almost full), I always unmount the card at boot time, only mounting if I need it. Custom b4 unmount, (upon remount I often get "settings isn't responding"), then rarely back to official after unmount, but usually stays custom! If I take card out then boot, obviously it's fine!

Wouldn't let me edit previous reply, this is more complete:
Thanx very, very much. Been bugging me for months, sometimes ok, sometimes not, couldn't see the pattern, Samsung tech support were useless. Because of continual media checking, with phone actually heating up! (150,000+ files, card almost full), I was always unmounting the card after boot, only mounting if I needed it. Device status was custom b4 unmount, (upon remount I often get "settings isn't responding" and/or "unfortunately, settings has stopped"), and stays custom!
Solution after your info above and my experimentation: Boot with card out, after completely booted insert the card, stays official, and then unmounting/mounting/unmounting still stays official! Rebooting with card in causes custom, so I'll just be going into flight mode at night from now on!
BTW, I regularly get this when I remove and check card, clean when I run it a 2nd time:

[Q] Unable to move apps to external SD on rooted phone

Hi!
So yeah i have a rooted i9505
When i select the option move to SD card it loads about a minute and says its on the SD card
But its still on the internal phone memory (well sometimes a few mbs of huge GBs games.
I also tried Link2SD and created a second EXT2 partition on my sd card and it said everything was correct
But even after "linking" the apps and it says they are linked correctly its still on the internal memory
How can i solve this?
I also already formated the card in the phone itself
Thanks

As for your first paragraph, it is working exactly as it is supposed to. In that regard there is nothing to solve.
As for the second, are you entirely sure that you're not merely viewing the symlinks that point to your sd card?

Well when i "Link" them to the ext sd partition and i look at downloaded apps or all apps it says 1 gb free
But when i look at "storage" it still says 1 gb free but the bar above shows almost about 1/4 free from 9.23 gb
So i think it maybe works but storage and apps still says its on internal?

storagemount also says 8.2 from 9.2 gb used internal
and ext2 sd 213 MB used but they were already used for formatting to ext2
and one game just dissapeared with Link2sd
i think thats why the bar shows less i cant find the game anywhere
Very strange
Edit
I rebooted the device after relinking in link2sd and now the dissapeared game is back in the list but now also the bar shows almost full so it was indeed because of the game
but i still cant get them on the partition while it says its there

How to fix 64gb files being corrupted and unsupported?

Hello, I just bought a 64gb sd card from sandisk. I formatted it a lot times, did the chkdsk thing. Formatted to exfat, to fat32. Still the same. Tried copying a lot of videos. But they always become unsupported. How to fix this? Need help badly

Format it as fat32.

You'll always get the Unsupported error when copying files to the device that a generic media device doesn't natively recognize, including MKV and PNG. You can ignore that error, hit "Copy anyway" and keep copying it. They'll work fine.
Has nothing to do with the partition format, it's due to MTP causing the PC to recognize the device as a Media Device. ExFAT is still the best option.
As for media files on the MicroSD becoming corrupted over time, that's an issue that has been around since the first MicroSD's in Android.

Well, it won't give the error, that's true. Mostly because you can't anything over 3.9GB to it.
The average 1080p film is 7GB. Slight problem.

I keep doing that, copying videos and musics. Thr first one or first 2 songs/vids will work fine. Then the next ones will become unsupported. Same goes when I record a video or music on my cellphone while the default location is on my sd card. They record fine but they become unsupported when I open them :/

That's weird. Is it only with the stock players or does it also happen with VLC and Quickpic?
(I thought you meant the annoying 'this file is unsupported' error Windows likes to throw out whenever you copy a png or mkv to the phone.)

Could be a fake/clone sdcard you've got there..

As above use to test.
