New sdcard on JB

Anyone noticed that we now have a /sdcard and a new /storage/sdcard0/
What's up with that

We heard you like Memory.
so we put your SD-Card into your Internal Storage.

/sdcard is a symbolic link to /storage/sdcard0
Essentially, they're the same thing (your internal storage) referenced in two different places. This is likely for backward compatibility to anything looking for "/sdcard".

is the data taking space multiple times? i have the same files in 3 different places
/sdcard
/storage/sdcard0
/mnt/sdcard
others have said they have the same files in /data - but i have nothing at all in that folder
how do i know which is the real one? i'm so confused i only saw mention of it today around the forums and have searched and read, but nothing is making sense to me (and you seemed like a nice fella to ask)

No it's not taking multiple space. The partition was changed in jb so this is essentially guiding apps which have not been updated to jb source a path way to typical information found on the sd card to essentially work or be backwards compatible

As stated here, /sdcard and /mnt/sdcard are essentially just pointers to /storage/sdcard0. An app tells the phone "hey, I'm looking for /sdcard!", and the phone lets the app use /sdcard, while writing the data to /storage/sdcard0.
I believe that some people are having a problem with the change from ICS to JB. From what I understand (I'm a new Nexus user, so I went straight to JB), ICS stored sdcard data at /data/media and had /sdcard point to it. So apparently some people are having problems with JB not looking for any data there, and instead looking in the new location, /storage/sdcard0. The data likely still exists in the old location, but since the pointer changed it isn't being referenced.

I noticed this, but my Play Music app hasn't, it cant find half my music. I have been using DoubleTwist and it has all my music. You would think that the Google apps would be the first apps updated to work.

I had this sdcard too and I though sdcard0 was the symlink. This thread cleared it up for me, thanks!

Removing SDcard/0

Hi, anyone know if theres an easy way to have the partition back to just Sdcard. Went from cm 10.1 back to touchwiz and of course all my directories are off now. Should I manually do move everything to SDcard? What have you guys done if you've run into this problem? I'm sure I'm going to switch to android 4.2 again sometime in the future so I don't want to continually be moving files. Anyone switch back and forth from 4.2 to 4.1 and can you tell me what you guys do to address the issue? Thanks.

Will wiping internal storage fix it?

No it's set up that way for the different profiles 4.2 allows. Each profile will get a different number.
It's always going to be that way unless they remove user profiles

Yeah I know theyre for 4.2 but I'm back on 4.1 stock touchwiz and want the folder structure to revert back. Do you know how to make that happen?

I am not familiar with the 4.2 partitions, so forgive me if this known, but when you say SD card, do you mean internal, or external? If it's your external, you could just back up all the files you want to your computer, format the SD card, and put the files back on. I think you can do this with the internal storage as well from a custom recovery. That should remove any partitions created by 4.2. It will obviously wipe all your data, so make sure back it up before doing this.

Ah just skimmed your post sorry.. and as far Sam I'm aware, they are just sym links
Meaning, just select everything from the 0 folder and past in the sdcard folder then ensure everything is gone from 0 and delete it

Yeah I just wiped everything including internal. Backed up everything first onto a PC of course. It fixed the issue, now there is only SDCARD. no
"0" :good:

I have this problem and my phone (cm10.1) won't connect to my laptop now. Do I have to revert back to cm 10? Because other than this issue everything else seems to be fine. And how do I fix both problems?

if you have TWRP as your recovery then you won't have to deal with /0/0/0 crap, /0 is only present in cwm for 4.2

How would I go from cwm to twrp

You can flash the twrp zip from inside cwm i believe but gotta put the twrp zip file for your device inside ur sd card and then flash or you can use rom manager to flash the twrp for your device but be careful and read up.

TWRP Wiping & Another Question on Safe to Delete???

I'm wondering if within it I wiped cache (All by itself, not dalvik) if it would delete all my installed app's or just set them back to default freshly installed as if I'd never opened and set them up yet?
Also I applied this mod http://forum.xda-developers.com/showthread.php?t=2036796 on another rom and later on decided not to use it anymore, but ever since removing it I am always getting on the very root base of the phone
extSdCard (Same as storage/sdcard1 )
sdcard (Same as storage/sdcard0 )
storage / emulated / sdcard0 and sdcard1
Which of those "sdcard0 and sdcard1" is safe to delete? I suspect this is from the mod I had before...
But I wiped my internal storage before flashing PAC-man 4.2.2, but now I keep getting a insufficient storage available on certain apps.and I have 7.19Gb's of space left on the internal sd. So I believe one of those questionable sdcard directories is making stuff go there then thinking I'm out of space of stuff.

Wiping cache would not do any of that to your apps. I'm not sure about your second question. On 4.2.2 roms, sdcard0 is internal and sdcard1 is external

Ok concerning the sdcard0 folder! If you went back to a TW Rom, and you now have that folder still there! Sdcard0 you can move everything (pictures, etc) from there over to the original sdcard folder. And then you can delete that other folder. And your apps shouldn't say anything about insufficient storage!
Same thing happen to my friend on here. And he had to do the same thing.
Because those 4.2.2.Rom's create, that folder?? and you know that already!!
Hope that helps you...

TWRP Format Data
Ooopsy crapola!!! Accidentally deleted my whole external sd card somehow. When I didn't even touch Wipe - External SD in TWRP...
Trying to hopefully recover all my files on my external sd card with MiniTool Power Data Recovery. -fingers crossed!-
Well now that the external sd card is gone what does Format Data do? Does it just format the internal sd or both external and internal?

Need help understanding SDCard

So when I was on stock my sdcard was located in /sdcard.
I then moved to CM and somehow my sdcard moved to /sdcard/0
I returned to stock because I was in need of taking 13MP picture, so my sdcard was then moved to /sdcard
Now, I moved to Unofficial geehrc4g_spr_us Vanilla RootBox [4.27.13] and all of my previous sdcard was missing (not lost, just replaced to a different folder /data/media) and my new sdcard is now /sdcard
Is /sdcard the same as /data/media ?? if it isn't, would it be safe to delete all the contents of /data/media? Or would that be wiping my sdcard?

I am pretty new to this device so my word is not law by any means; I think that the files in data/media are nothing more than a mirror of /sdcard. Otherwise, you would have blown through all available memory trying to store doubles of all data(at least it would for me, I has this badboy 25 gigs full the first day.......)

Actually my /data/media and my /sdcard have totally different files.
Here is an example : my /data/media has all my downloaded roms and mods and my /sdcard has no downloaded roms

If you go back to a stock rom and take everything in /sdcard and put it in /sdcard/0 then go to an AOSP rom, it'll all be where you expect

does anybody know a quick way to format the sdcard (without wiping the rom)?
I just want to start fresh with the sdcard, I believe that my sdcard has duplicated many times since flashing stock, CM10, and rootbox.
It has been replicated on "/data/media", "/storage", and "/sdcard" and in those folders a "/0" folder has been created as well. I now only have 6GB of space.
Whereas, before the multiple sdcards I had 16-18GB available.

OKayy so will doing this stop the duplicating and mirrored folders and enable stock and aosp to share and get along (as fas as this situation goes) using the same directory?

[Q] Scared to go to 4.2

Im on 4.1.2 right now and i went to a 4.2 rom, had everything moved to storage 0 and somewhere along the line, i basically lost everything because my storage card wouldnt work on the 4.2 rom anymore. i know, its still in storage 0 but for some reason it was corrupted. even after I formated it 3 times. so i switched back and the sd card worked again.
Do i still have anything to worry about? because i want to flash a new rom. 4.2...

It will still do it, nothing has changed. I always back everything up onto my computer then flash then format again to fat32 then move stuff over.

It is not recommended to go back and forth between 4.1.x and 4.2.x ROMs. 4.2 handles storage differently. What 4.2 ROM did you flash? Here's a link explaining the storage structure in 4.2.
http://teamw.in/androidmultiuser
I had one occasion (and that wa the only time it happened) where AOKP 4.2 reported my external sdcard was corrupted. I took the sdcard out, tried it on my tablet and laptop, both worked fine. I cleared cache/dalvik cache, reinserted the sdcard, rebooted AOKP and it worked fine again since.

Going between 4.1.x and 4.2.x can result in some pretty weird stuff, but as long as you backup your files, wipe /data and /system or format them it should be fine

Pretty sure its only 4.2.2 also.

I too had the 4.1.x > 4.2.x freak out with my files. Nothing has ever been deleted though. Just transferred to data/media/0 for AOSP (4.2.2) you should back up the entire SDcard as everyone before me said. Its nice to have a back up all the time cause weird things do happen.

Just for your information, the storage "0" folder only contains the LINKS(shortcuts) to your files and folders.
The actual files and folders are not located there at all so unless you really formatted the internel /sdcard all
your files and folders are intact and still on your internal sdcard.
The 4.2.x roms work the same way as the 4.1.2 after flashing the 4.2.2 rom you will again have a folder called
"0" and it will contain shortcuts to all you files and folders which are on your internal scdard /sdcard
It is safe to delete the "0" folder if you want to flash and use a stock or stock rooted Samsung v4.1.1 Touchwiz based rom.
