error mounting sdcard after moving apps to sdcard

on GDXv25 abd alfv8a have all the extra goodies for vold and all that. I change my SDCARD to a bigger one. format a partition for ext4 and leave the rest as default. On moving old stuffs back to it it seems to behave very well. Then I decide to move some of the apps to offload internal storage. The moving seems totally ok but after reboot my sdcard seems not be able to mount anymore. Go into CWM recovery and try to mount my sdcard. It says error mounting /sdcard yet I could succesfully mount my ext4 partition. At this point should I go ahead and re-format the sdcard again? What happens to those apps that I offload to the sdcard? are they toasted?
I'd to get some opinion before I re-format it since it will bring me over the point of no return. I still have no clue why all of a sudden after the moving of my apps that the partition won't mount anymore

On my linux I try to mount it via USB... it gives an error saying can't mount coz it can't read superblock. I gather some operations must have wiped into superblock. Sh*t hits the fan so to speak

by the way it is a new sdcard ... I dun think i damage it. But from CWM I can't even go ahead and format it because it says error mounting the partition.
I am amazed - I thought you don't need to mount before you can format. what's the deal here? I can't mount and I can't format?

That error message simply means that the ext filesystem in the sd-ext partition is kaputt and needs to be repaired (for example, manually restore a copy of the superblock) or formatted.
And that's your reason why you ran into problems ... something went wrong as you moved your old stuff onto the new card, and the next app you put onto the sd-ext finally triggered the problem.
Of course there's also the slight chance that the phone doesn't like the SD card.

finally I am able to format that sdcard by inserting into my kodak video playsport camera and format that from there! It's ridiculous that under CWM I am not able to do something as simple as formatting. That should not be a "feature" at all! Error mounting the card I could accept that but not able to format a card with screwed up superblock that's not acceptable.
With this exercise, I realize how valuable a backup it is. With all those apps xferred to the sdcard, I practically cross a bridge. Even with old usable card re-insert into phone those apps are gone and are no longer available. Only a backup (of course on a usable putaway MMC card) could have saved me all the trouble.
I still dunno what have gone wrong in the first place. Perhaps there's something I dun quite understand about moving apps to xternal storage.

[Q] Unable to mount /data or /emmc

My i9305 is routed, and has clockwork mod installed on it, still running the new EE 4.1.2 official rom thought.
Im unable to mount the data partition in clockwork mod which means i cant create any backups of my phone as it fails.
The internal sd card partition wont mount either when i try and intsall a zip from internal sdcard i get cannot mount /emmc.
I think my partitions are messed up and i probably need to reflash a PIT file to get them back in the right place.
Can anyone confirm that this is right?? And if http://forum.xda-developers.com/showthread.php?t=1950591 is the corrrect PIT file to use for me?
Thanks

Hey,
which version of cwm do you use?
I only know the emmc error from the 6.0.1.5 touch version in the dev thread.

Dont play with .pit files restore to stock factory reset then use cmw

Thanks for your suggestions; I’ve actually managed to fix it now.
I actually forgot to mention a fact which as it turns out was the reason for my problems.
The device was encrypted and CWM can’t deal with encryption or the encryption would be useless!!
I unencrypted the device and I’m now able to mount both partitions.
Can’t believe I didn’t think of this in the first place and nearly flashed a pit file!!!

help, problem with internal storage

Hi at all, I've a problem with my samsung galaxy note n7000, I have the latest 4.1.2 original samsung touchwiz , I've only rooted it,
the problem is that the android os doesn't mount the internal sd card, and get me a notification that say "blank usb memory or not supported file system", I tried to reboot custom recovery(philz recovery) and wipe data and cache, format sd card but nothing works, can anyone help me????

Did you format it to fat32? In recovery did you try formating the external storage?

*bump
I'm facing the same problem right now. It occurred after I did a hard reset. In the best case scenario, this is just a partition table corruption, but in the worst, a physically damaged card.
On Linux, I have fixed partition tables with a nifty tool called gpart (not gparted). There is a similar utility available for Linux, Windows, Mac etc. called TestDisk. Unfortunately, these tools are not available on Android. However, there is something called aparted available on Play Store that supposedly fixes filesystems.
I have installed it, but it wants to install some browser addons too. I've tried to repair the filesystem that it shows as empty, but no luck so far. I will shortly check its online manual, but I hope we can get something like gpart on Android.

Hi, I have been able to get the Internal SDCard (/storage/sdcard0) mounted again, albeit with loss of data. Look at my recent post http://forum.xda-developers.com/showpost.php?p=48595569&postcount=24
and the one from which I got the hint
http://forum.xda-developers.com/showpost.php?p=35726016&postcount=6
The step by step procedure is here: http://forum.xda-developers.com/showpost.php?p=26285877&postcount=12
but if you have only one partition damaged, you could just check it with e2fsck and then, if necessary, recreate it with mkfs.exfat or the other method in the referred post.

I don't know if you can recover your original data - I had tried formatting the partition, by mistake, to ext4 with mke2fs. You could avoid this, and see if you can back up your partition with dd before re-formatting it to fat32.

solved, I download latest frimware, and flash it throught odin and all are fixed

[Q] CyanogenMod 10 - lost my sdcard

Hi,
Long story short I was messing about and have destroyed my sdcard partition.
Android still works but, it can't see the sdcard. If I plug the touchpad into windows it offers me to format it...
I have a nandroid backup but, if I format in windows to fat32 and copy the backup over to the sdcard and then choose to install from zip I get no files found.
Should the partition be fat32 or should it be something else? I am on cyanogenmod 10.1
Cheers

ok i think I need to partition it via CWM.
However, it asks for EXT Size and SWP size.
ANy suggestions? I am on hp touchpad 32gb and cyanogenmod 10.2##
Edit: tried that but, while I can now see a lost and found folder so the sdcard partition seems to be correct. When i go into windows it still asks me to format the drive. I still can't copy across my nandroid backup. Help how do I fix my sdcard partition?

unable to mount internal storage due to encryption

Long story short, I've been trying to get into my internal storage via TWRP but its saying that there are 0MB in the internal storage and that there is nothing in the sdcard folder
I've tried formatting it, hasn't worked
I've tried changing the format to FAT and then back to EXT4
then after that didn't work i tried the same but with EXT2 , it showed the amount of storage but still didn't let me see what was inside of the sdcard folder, whenever i'd go in there its just completely empty
Can I please have some help with this, I've been stuck on this for a couple hours now

Ouch! Please don't say that you just formatted userdata (/data).
You've just killed all your data on your phone.
No, I'm not that experienced with TWRP and I don't know which versions under which circumstances it can mount userdata.
I use custom recoveries and just presume that I can't mount userdata in them.
In the normal system (which mounts and decrypts) I use normal tools to sync or backup.

I didn't format data it self i meant that i factory reset it, sorry i should of been a lot more clear on that

Oh, ok.
Well, in any case, if it's encrypted you need to mount it not with a simple "mount" command but something fancier using dm.
They don't try to make it easy to do.
Unless you're destroyed your system and you're trying to recover your data, whatever you're trying to do is best done in the normal system.

never mind i found a fix for it
well not really a fix just a way around it
thanks for the help ^^

I had the same issue so I flashed a raw firmware after taking full system backup. Now TWRP is working fine.
