[Q] Upgrade to CM11 and can't access extSdCard - Galaxy S III Q&A, Help & Troubleshooting

i9300
I've upgraded to CM11 (full wipe and format) and I am unable to access my extSdCard from the phone. I have no problems access the SD Card from an adaptor in the PC.
Es Explorer can read, but cannot write.
in CM11 storage menu, I click on erase SD card, but it still don't have full permission to it. However I am able to create folder in root browser.
I've tried chkdsk and sd card has no errors.

I tried to follow this, but it says invalid mount argument
su
mount -o bind /mnt/extSdCard /sdcard/external_sd
I've created this folder (/sdcard/external_sd )

I had similar problem after I rooted and installed TWRP and when I used Link2SD app it kept complaining that it could not mount the 2nd partition of the SD card I tried formating a few times using
Minitool on my PC and a card reader to attach the micro SD card.
I ended up creating partitions then running option wipe in Minitool using 1's then fomating 1st partition to FAT32 primary and 2nd partition to ext4 primary (I had already tried formating to ext2 & ext3 with no fix) I did not enter a lable name for either of the partitions, both partitions set to primary.
Note also that I ran Minitool surface scan on both partitions and reported no errors, thought I would do this before I installed SD back in to my phone.
On completion of the above I installed the SD card in to my phone ran Link2SD and it recognised the second partition and mounted with no errors and when I look at storage in Link2SD both partitions
are seen and I am now able to link apps to second partition with no errors.
Hope the above helps in some way, I am learning all the time thanks to XDA members.

As an idea: Check your "platform.xml" if write permissions are given. See here.

I think the problem lies at recovery. I suggest flashing an older official cwm recovery from the official website. Since i did that ive had no mounting issues at all.
When i first rooted my s3 i flashed twrp and had issues with preload, same with a later cwm.

accidentally formatted sd card

help, I accidentally formatted my sd card. After rebooting, I always get the message that the sd card is blank or has an unsupported file system. I have tried different ways of formatting (ext4, ext3, fat32, fat32+ ext3) but no success so far.
Anyone has a solution? I am using modaco 2.8
D
With Astro or similar first back up your applications,secondly go back to recovery and go to bottom to mount sd card so that you can copy backups folder to your pc.
Now reformatt and make partitions and remount sd card to copy modaco's rom and choose zip to update. I dont think there is easy way round.
So you are saying the only way to fix this is by reflashing?
BTW, if I have to flash anyways, do I need to setup a fat32 partition or can I format the entire card as ext4 (i don't use windows on my pc)
Without flash your applications may not work correctly but you can try.
I think just ext4 will not be enough because how are you going to transfer files and folder which needs fat32?
Your current ROM will have automatically put files in your sd card which got destroyed by accidental format.

[Question/problem] Can't mount sd card

Hi. Noob Android user here
So. I turned on usb storage and formatted the sd card from windows. I copied some files onto it and after i turned off usb storage it said "SD card is safe to remove" and i don't seem to be able to mount it back.
Thank you.

try to format it thru phone
Tried that a couple of time and it didn't work. After a couple of reboots it worked now. Thanks.
Still got a question though.
What are the correct settings for formatting the sd card from windows?
Is it necessary to partition it from CWM? What are the correct setting for this?
LE: Ok. I got myself deeper in trouble. I managed to format the sd card from CWM. I mounted the sd card and copied update-cm-7.2.0-RC1-p500-signed.zip over. I wiped the phone's memory and tried to install CM7 and got the following error: "E: Can't open /sdcard/update-cm-7.2.0-RC1-p500-signed.zip (bad)". I also tried with update-oxygen-2.3.2-LGP500-KANG-signed_v2.6.zip but doesn't work either.
I was thinking of trying to partition the sd card from CWM but i'm afraid i will make it unable to mount back again and this time i got no android to format it from.
Also it seems that formatting the sd card from cwm doesn't really work. The files are still there though it says that it completed.
LE2: I managed to mount sd card from cwm and copied over a cwm backup folder i had in my computer. Takes a while to copy it like it really does something. But after i try to restore or remount usb storage the files aren't there anymore.
can you tell me why do you want to patition your sd card? do you want to create second partition (sd-ext) or what?

Just format your SDCARD from SETTINGS - STORAGE, after that proceed with the instalation of CM7 or whatever you want. Don't partition your SDCARD if you don't know how to do that and if you don't need partitioned SDCARD. It is not necessary to do that if you don't use an APPS2SD app, so don't waste your time with that.

[Q] error mounting emmc and cannot detect external sd card

Good day,
I am using SGS2 i9100g.
I have flashed from CM10.0, JB4.1.2 to pacman 3.00, JB4.2.2
ISSUES:
1. error mounting emmc and cannot detect external sd card
2. When i want to use camera or gallery, there is an error saying "No external storage available"
Attempted solutions:
I have tried the following but it does not solve my problem
1. re-flash the custom rom and gapps. (full wipe with wipe cache and dalvik cache)
2. reformatted my sd card to fat32.
3. went to recovery to unmount and remount my external sd card
4. tried to mount emmc in recovery but returns an error "error mounting emmc"
5. off and on and also rebooted my smartphone
6. tried these codes shown at the bottom(to manual remount)
$ su <enter>
# mount -o remount rw /mnt/sdcard<enter>
Side notes:
- I am not sure whether is both related in terms of cannot mount emmc and not detecting my sd card.
- My sd card can be seen in storage with many free space(new sd card) can unmount and mount but the "Mount usb storage" is sealed, my internal storage also can be seen with a lot of free space.
- I am not sure about this but i have googled and saw that some people said that cyanogenMod has bugs regarding the folder of sd card and internal memory directory are swapped(or something like that)
- By using ES file explorer i can see mnt/extSdCard(which is my external sd card) with my files inside but in my mnt/sdcard(i am not sure if this is for internal memory) there is nothing but i cannot find emmc folder inside /mnt.
- I have a storage folder which has sdcard0 which contains nothing, sdcard1 which contains my file in my external sd card and a usbdisk0 contains nothing also.
- Now i am not sure which is the cause of the problem where i cannot use my camera phone and gallery
Please help and thanks in advance
Every help and suggestion is appreciated
SOLUTION!!!

I have found a solution. Just reflash back to stock and then flash to custom rom.(repartition with an uncompatible .pit file can cause a traumatic event to a person i.e me )
ATTENTION!!!
DO NOT MESS WITH .PIT FILE!!! I've did a mistake earlier and i've paid the price of bricking my phone. Plus when you meddle with the wrong .pit file, it will corrupt the internal memory and as far as i have searched through the xda forum, nothing works and re-flashing back to stock rom can also cause problems.
Hope this information will inform all of you so that you will not make the same mistake as i have done.
Peace

Do you think it would work if I just redo repartition with a known correct PIT file?
Or going back to Stock is a must?
Thanks!

Can you connect your sd card to a pc. Maybe you can format it as ext4 for using Windows

External SD card always mounted as read only - no more ideas

4K android media box with AML812 chip. 2 USB ports, 1 USB OTG port and one SD card slot. Android 4.4.2 (KitKat?)
USB drive connected with FAT system is mounted as read/write device, all SD card I have tested were mounted as read only.
At first I wanted to make firefox to download files to SD card. But firefox had no rights to write to SD.
At second I thought that firefox can't write to SD because new privilages system in KitKat. So I found a solution on the web and have added media_rw entries in permission.xml file in WRITE_EXTERNAL_SD section. But it didn't help.
Then I have found out, that SD card is always mounted as read only by default (by terminal and mount command) - i tried 3 different SD cards, no success.
I have checked SD card with fsck_msdos and externally on my desktop PC - SD card had no errors.
I tried to remount SD as read/write with mount -o remount,rw device from terminal and it worked but apparently only apps with root privilages can write to SD. Firefox still can't write to SD.
And if I close terminal the SD returns to read only state.
Don't know what to do, where to find the solution.
In vold.fstab there is only one command with dev_mount, and this command doesn't have read/write or read only flags (checked dev_mount in the web).
There is no fstab.device files on the box, which are common? in KitKat (above android 4.3) so I am not so sure that this is KitKat device.
Please help to unlock SD card write rights.
EDIT: formatting to exFAT, NTFS or FAT32 with 32KB chunk size didn't resolve anything (advice from some android forum). My device doesn't recognize exFAT, and the rest give me read only mount point.
I installed Paragon exFat, NTFS app. It can't mount SD correctly at all. It unmounts mounted SD very good though. It can't check and fix SD because /dev/block/mmcblk0p1 is read-only file system.
The same goes for format - Error 0x1e from mkhfs.
When I try to mount SD with Paragon nothing happens (the mount button is still active, and unmount is inactive), and android memory settings show that SD card has been mounted as 803 MB card, not 16 GB card (14,84 GB exact capacity). Paragon can only unmount SD.
Now I see that I can't even format SD card from android memory settings. When I choose format, it unmounts SD card but then nothing happens. There is no format operation going on.
Really I don't have any more idea.
