I got some problems with the write permissions on my sd card. From time to time my permisiions switches to R/O, although Root explorer doesnt show it. I need to switch to R/O and then back to regain write permissions. If i dont do that i cannot write or delete any file from sd card and i get the "Error deleting file" message. This recently happened afther playing Assassins Creed and the game could not save data. But the situation occured a few weeks ago when the game was not installed and did not know the R/O switch trick, so i had to format the card and do a clean flash.
I dont have long named files on the card (the kind that cannot be deleted by windows OS). All the files that innitialy could be deleted and/or moved become read only, like the sd card gets locked or something, and the only way to unlock it is the way described above.
Writing permissions on sd card are also not modified in Root explorer.
Any idea why this happens? I looked around and find others with the same problem but no solutions.
My card is a 16 Gb class 4 Kingston.
Also, it seems that the error occurs while connected to usb, and removing write potect using Root explorer doesnt work until disconnected.

Ok, I have a very peculiar problem which I cant figure out. Here is what happened:
1. Update to 2.1 with Bin4ry flash tool
2. Root with Z4 root tool.
3. Install Apps2SD using following method : http://forum.xda-developers.com/showthread.php?t=804574
4. Install Black HTC theme: http://forum.xda-developers.com/showthread.php?t=821790
I then noticed that my Market app wouldnt work properly, I could browse and begin downloading apps but it would Force Close evry time just before installing them. Not knowing which step broke it I decide to start over as follows:
1. Restore to 2.1 with SEUS
2. Check Market, all appears fine.
3. Root with Z4 root tool.
4. Check Market, all appears fine.
5. Install Apps2SD as above.
6. Check Market, all appears fine.
7. Install Black HTC theme as above.
8. Check Market, FC issue rears its ugly head again.
I checked through all of the stages in the theme and I cant see one where I could have broken the Market app, very peculiar. I was playing around on my phone and installed a couple of apps from .apk files on my SD card, I then tried to back these up using Appmonster. It told me it couldnt write to the SD card, very odd. I then tried a simple copy and paste with Root Explorer, same problem saying it cant write to SD.
I rebooted and got all sorts of Force Closes so I am pretty sure the SD has got corrupted or mounted Read Only some how, but I cant figure out how.
I dont know if it is related but when I plug my phone in to the computer it cant read it as storage, I have to turn the phone off, remove the card and use a card reader to transfer data. It seems to me something is wrong with how the phone is mounting the card, but i cant see where it was changed. I am pulling what little hair I have left out with frustration at this, any and all help is greatfully welcomed.
Quick update, I put the SD into my Linux computer and tried to change the permissions to 777, no joy. Is this likely to prevent me writing to SD, and hence the problems? I understand that FAT32 filesystem doesnt support permissions, how can I make it work with a FAT32 partition?

Your app2sd partition is ext2 right?
Somehow SD card is read only. I can't take pictures, delete files etc. Astro file manager says "Error deleting file" if I try to delete. Phone reads files but can't modify or delete. Can I remount SD card read-write mode using Terimnal Emulator? It seems that phone can't index files. Usually it took few minutes after reboot, now the phone shows indexin message for a moment and then dissapears.

can the pc read it when mounted on the phone?
is this a brand new sdcard?
try reformatting thru the pc...make sure it's fat32 and not ntfs.
Connected phone to computer and found corrupted folder LazyList on the SD. It was not possible to delete files from this folder. Fixed it with windows command line program chkdsk and removed corrupted files. Now it works fine.
Today i was transferring files from my sd card when suddenly the connection was lost. Now i cant delete things from my phone using a file manager. it always says error deleting. what do i do, format it?

That happened to me before. Try to back up all of your SD card contents onto your computer, then wipe the SD card from the settings menu and copy your stuff back. That worked for me, and fixed a couple of FCs I was getting.
another problem with my sd card. every time i connect to a computer it says do you want to scan and fix. i said no and now it takes my computer forever just to read the thing what should i do.
So i have been having this problem for a few months now, and its driving me crazy.. I've read every thread on XDA about sdcards, but nothing seems to apply here
When I reboot, my phone launches External2Internal so my 32GB SD can be used as my internal drive, and I've used it fine for a very long time.. but recently the sd card just disappears after some period of time. it seems to happen whenever my phone goes to sleep or the screen goes off and is locked, i suppose
after I reboot the phone it works fine again..
I quite think its from a malicious program.. but I cant be sure
recently, I installed a bunch of sd card tools to rescan, remount, test etc.. and I also installed an External2Internal update... and after all that, the sdcard contents appear to have been deleted, even after multiple reboots, when viewed with ES File Explorer.. However all the contents appear in good condition when viewed with Total Commander.. .
and since all that tinkering, because the sd card seems on some level to be deleted, programs like avast are getting corrupted errors on their virus scans, such as "invalid context during scan".. an error it doesnt get when the sdcard is unmounted completely, but only now that it mounts as appearing mostly empty to es file explorer and probably most other programs.
so it seems like one of the USB tools or the External2Internal update has done something malicious to my card... or maybe it was a last ditch effort by some dorks malicious code from a program i deleted in trying to get this all sorted out
anyone else having this problem or know how it can be fixed?
and I prefer to try and find out what is causing the problem and fix that problem, rather than just reformatting the card or buying a new card, since i'm sure it will just happen again someday
thanks

This happens to me as well, the only difference is that I don't use External2Internal but the jellybean option "default write disk: SD card"
Hi guys,
My external memory card has all of a sudden become undetectable. Inside root explorer it appears as a file and not a folder. When i try to see its permissions it is set to read only. I changed it to read write but still its not detectable. Moreover it changes to read only on every reboot.
I was on Resurrection Rom v 5.10 so i updated to v5.14 with full wipe. Still the issue remains.
I have searched on google and it appears to be something related to kitkat. I tried a few solutions like running 3rd party media scanners or editing the permission.xml but all in vain
I tried installing other kitkat roms like Neat Rom v5.8 ..now i can see the extSdCard as folder but when i open it its blank...Moreover i can see the permissions set as rwxrwxrwx in root explorer,but if i manually go to set permission for the folder it gives a popup saying "extSdCard permission cannot be set because the file system is read only"
I tried installing stock JB rom via odin but still it didnt help ..
If i try to mount external Sd card from cwm it gives error saying"Can't Mount "
Note: I tried 3 different SD cards and all went undetected where as they were detectable on other phones.
Need help guys.
Attaching few screenshots for better understanding
If you are unable to read the card's data then consider it lost. Connect it to your PC in USB mass storage mode, it should appear as a drive. If you can read the data, take a backup else leave it. Now format your external card using windows.
It should fix the issue for you.
