Storage

I have a few general and a few specific questions regarding storage:
1. Why did Samsung create 2 directories for internal storage? It has regular internal storage and "SD" storage but both are really internal storage. Why not just make one big partition and SD storage is actually your removable SD card (this is how it was on the OG EV) Someone please explain this to me if you know the answer.
2. On CM9 rom how do you save apps and their data to a external SD card? I'm trying to install a Gameloft game but it's saying I don't have enough space available which I certainly do.
3. On TW based ICS roms how do you save apps w/ data on the actual external sd card? Possibly planning on trying out Rujelus' rom so I'd like to know before hand.

The OG evo didnt have an emmc partition. It had internal storage dedicated to things like app storage, same as any other phone. You cant mount internal storage to your PC so combining these would be a waste of space.
You might be able to push game data from emmc to the sd card and they might still locate it but I have never tried as I never fill up my emmc, I just keep everything else on the sdcard. But worth a shot.

I don't quite get your reply but to make things easier for myself what is the best way to format the SDcard. I am talking about the internal SDcard not my actual removable micro SD card. I know there is an option in storage but I don't know what SD card its referring to.

Just remove your external then hit the format option in storage. And if you move back to the fd16 kernel on cm9a3 you will be much happier with the way the storage is handled.

Can A Backup Be Made On The SD Card?

AT&T GS3
I have looked over and over. And I see articles mentioning how to backup your device before Flashing ROMs. They even show how to do it. One of the articles said it could be done and how to do it. I did it and just like the other ways I tried the backup is stored on the Internal Storage.
I have all this room on my SD card available. My internal storage is almost completely filled with me not being able to store games or any apps for that matter on my SD card. Right now I have about 4GB left for my Internal Storage. After the backup I had 1GB left (I deleted the backup on the Internal Storage).
Is everyone else just storing the backup(s) on your Internal Storage? Your computer? SD Card?

Well you can backup to the internal sd card a d once you made a nandroid you can move the folder "clockworkmod" to your external sd card. And once you need to backup just move it back like a storage kind of thing. Tbh I'm not sure if you can make a backup to your external but I would always save it on your computer if anything happened to your phone

Thanks. I think I am going to go ahead and do it the way you said. Have a good one.

I do it this way but would prefer to backup directly to the sd card.

TWRP can do nandroids on the external sd.

I had to look up what TWRP was. LOL
Anyway, I looked it over, decided to try it and it worked! I now have my device backed up on the SD card instead of my internal memory.
I want to thank you and the other person for the helpful info. Each of you helped point me in the direction I wanted to go. Have a good one.

My cwm automatically backs up to external sd card. I'm pretty sure most versions do this now but can't verify. Also when I flash zips it will look in external unless I choose install zip from internal sd card

Doesnt work with the newest version of cwm. It worked with the 5.5.0.4 one though.

Safe to delete?

So I came across this directory /storage/emulated/0, and it seems to be a copy of my system that I have under the internal sd directory...
thing is it takes up 2gb. what exactly is the emulated/0 directory and if i already have this all under internal sd is it safe to delete?
some more research and I found the answer... for anyone else wondering.

never seen this before as all my other phone were HTC and had a different folder structure.

It's en emulated mount of the SD Card.
You can't really delete it the mount, bu deleting the files in it will delete them from your SD Card.
It says 2GB of disk usage, but it's the same 2GB of disk space you are using on your Internal SD Card. It's not a different 2GB.
In other words, don't mess with it.

how to move twrp backups?

Right now, my twrp backups is stored in my internal storage. Can I move that to my SD card? And how? An easy way would be appreciated.

Just copy the TWRP folder from the internal to external card.

SD card and Internal memory

I just moved from the Sensation XE to the M8. The Sensation has a SD Card and the internal memory and no emulated SD Card.
So how do you control where the apps stored their data?
Is the SD card only for data (music, pictures and storage), and the emulated SD card in the internale memory for app data and such?
And finaly, where do you guys keep your nandroids - emulated SD Card og SD Card?

That's pretty much it. The internal memory is essentially an emulated SD card. App data, backups are going to be saved there by default. Nothing is going to be saved to the removable SD unless you take a specific action to do so.

I keep mine on the internal storage. Not even sure recovery will allow you to read/write a nandroid on the removable SD (although you can manually copy or move if you wanted).
But I normally just keep the latest known good nandroid on the phone, and move others to my computer "just in case".
Even with ROM zips, some folks have had issues with recovery (at least TWRP) not consistently recognizing the zip on the removable SD; even though you should be able to browse and find zips on either the internal memory or removable SD. It seems safest/easiest to have the ROM zip on the internal memory (or at least know how to adb push it there).

So when you flash a new custom rom, is the emulated SD Card left alone or is it also wiped?

Usually left alone, but there is a buggy TWRP, possibly official 2.8.0.2, that has wiped cards, if I have followed correctly.
TWRP can write backups to external card and read from there too. That's what I do.

Good to know, I was wondering exactly that.
