Will wiping out device wipe out the content in /sdcard/ ??

Hi,
Sorry for being a noob but i came from android phones with sdcards and this is the first time i had one without a sdcard card slot..
the main question is, if i wipe the device, will the content in the /sdcard folder that i transferred via MTP (photos, music, Nandroid backups, etc) be wipe out as well?
I am asking because I swear the i did a wipe yesterday and ALL the content in the phone is gone, including the things i put in the /sdcard folder...
just need to clarify or maybe i am crazy? Please help..

There is no SDcard. Its all one big partition. Doing a factory reset wipes the entire device. Yes your pictures and videos, too.

Yes, the /sdcard folder actually points to /data/media. Doing a factory restore resets the /data partition, including the contents of /data/media. This means everything put in /sdcard will be erased.

That's stupid. Really stupid. I factory reset my phone all the time... Am I supposed to copy everything back over every time... Eh that would suck.
My transformer and G2x had internal memory and a factory reset from clockworkmod didn't touch the internal storage.
Nvbackups would copy everything though.

Instead of doing a factory reset, you could just delete everything in /data except for /data/media. That will achieve the same thing and leave your media data alone.

Wiping data and cache in CWM do NOT wipe my whole phone what are you guys talking about? The /sdcard is treated and mounted as if it were a physical SD card.

Yeah if you just wipe your data/cache via CWM it DOES NOT touch anything in your /sd card. However doing a factory reset via the settings menu while booted does!

ok just to be clear, because people (me lol) get confused when people talk about the SD card when talking about the nexus. obviously there isnt one...so im assuming the partition that handles the media is what u refer to as the Sd card...virtual sd card. correct? and if i wipe data/cache via CWM it does NOT wipe my pictures, videos, etc...but if i factory reset under settings while booted...it WILL wipe EVERYTHING...i think i got it now if what i just said was correct...

+1.. all these people are thinking the phone doesn't have a "sdcard." There is a "sdcard" but its more like internal storage. Think of it as a computer,
- Older phones like the G1 rely on the SDCard fully... so this is like running a OS off a USB drive without internal storage (G1 has a little internal storage.. not enough to say that there is one)
- Phones such as Galaxy S1/S2 have a sdcard AND internal storage. What does this mean? It's like a internal hard drive with the ability for external storage (flash drive, sd cards).
Example: Galaxy S2 has 16GB internal storage and expandable storage.
Phones like the Galaxy Nexus, Nexus S, Galaxy Tab is like.... internal hard drives without the ability for expanded storage (unless you USB OTG a flash drive!). This is just a beyond misconception on the scene and this is what they meant by not having a sdcard.
When you do a factory reset, wipe cache, wipe dalvik... your /sdcard/ IS NOT TOUCHED unless you run a script that says otherwise!
/sdcard/ and all the other folders are treated as two separate partitions!

When you unlock your bootloader and it wipes, that deletes everything, including the sdcard folder.

yea i was about to say this is incorrect information, if you want to wipe everything i believe in the ARHD thread there is a wipe script to wipe everything, even data/media

Super wipe lite from the ARHD thread does not wipe the virtual SD card.
--- This script will erase and format your system and cache partition using EXT4 file-system ---
--- It will also wipe /data partition, but /data/media (virtual SD card) will be untouched ---

All your personal files that would be stored in SD Card in other devices which has one, are stored under /data partition, at /data/media/.
The /sdcard/ is just a link to /data/media.
There seems to be special handling in CWM recovery image for Galaxy Nexus when formatting /data partition as it will not touch /data/media. It's nice feature indeed, but you cannot now empty your /data/media content without manual work. But normally you don't even want to do that so it's fine.
It would be much more simple to just forget about the "virtual sd card" or /sdcard, since those are just, well, virtual and makes unnecessary confusion.
So our files are now stored like they would be under C:\Users\media. If you format C-drive, you'll lose your 'personal' files as well from media folder. The "virtual sdcard" /sdcard would be just a similar as Windows has as "Favorite" feature, just a shortcut to a certain folder location.

hey guys,
found this thread searching for an answer, i'll go ahead and ask it right here as it fits the the topic:
what i want to do when installing another rom is to wipe (system) data, cache and Dalvik cache (and i do not want my private files on the sd card to be touched). it is clear to me that CWM does not touch the sdcard partition. BUT: since all the apps are installed onto the sdcard partition they won't be deleted, right?
i want all my apps to be gone and to have a completely fresh new system installed without ANY leftovers from apps or apps/data or anything else that got stored on the sdcard partition while using the previous rom. of course these apps would not be installed anymore when you boot up the new rom, but all their files and folders would still remain on the sdcard partition, right? i'm talking about all those files that the rom generates itself and stores on the sdcard partition. of course i want to keep all my music, downloads, pictures, etc. but i want everything else to be gone.
to my understanding cwm does not touch the sdcard partition which leaves all the app folders and other android-created-files and folders (that were automatically created when using the previous rom) untouched and i would have to manually look for all these files and delete all these remnants which is kind of annoying.
do you know what i mean?
thx and greetz,

When you clear all your data/cache when installing a new rom it will also wipe apps that have been installed on your sdcard. This does not include removing folders that apps may store additional data on the sdcard. If you want to remove these folders unfortunately you will need to do it manually.
Sent from my Galaxy Nexus

Installed apps do not go in /data/media, but /data/app and /data/data. I dont think /data/cache exists, /data/dalvik-cache does.
Those are only erased if you do a wipe data/factory reset in cwm/twrp, and for the latter wipe dalvik cache.

Quick question on wiping data & "SD"

Will wiping the phone in CWM delete files on the "SD" space of the phone? I've read it is all apart of the same partition, so I wanted to make sure before awkwardly deleting the ROM I am about to install..

I have wiped tons of times in CWR and it hasn't touched the /sd yet. All my files are safe and sound.

Yes, it clears *all* internal storage.

So...which is it?

Maybe I misunderstood but are you talking about wiping /data and /cache? Because when I do this it does NOT wipe the /sd but does wipe all other user data, just like on every other android phone I have had.

Wipe data/factory reset on CWM wipes your WHOLE phone, including "SD" card. I advise you to use the Super Wipe Lite script from the Android Revolution ROM, get it here. This will do a complete wipe, except SD card.
A bit of more info, in case you're interested: the SD card is the folder /data/media mounted as /sdcard. When you wipe in CWM, the data folder is emptied as well.
EDIT: i havent actually tried to do a normal full wipe from CWM, im stating the above just from reading other reports here. Maybe the last version from CWM has fixed this, i dont know
EDIT2: You can wipe cache and dalvik as usual from CWM without any problems.

I figured that was how it was setup, but didn't know if CWM had any logic built into it to filter out the folder. I'll take a look at the script, thanks.

The built-in factory reset in Android will also wipe everything.

I did data,cache,dalvik wipe and formatted system going from 4.0.2 to 4.0.3.
I did NOT lose my SD card

The default wipe in ICS clears *all* internal memory. The default Factory Reset feature of CWM does the exact same thing. I've done it twice and it wiped fully both times.

Very interesting direct contradictions going on in here..

Wiping data in CWM DOES NOT WIPE THE VIRTUAL SDCARD. People need to stop saying it does.. it is all one partition but the virtual SD card is not wiped when you wipe data in cwm.. Factory resets in settings will wipe your virtual SD card but cwm WILL NOT.
Edit: sorry I had a long night, but I will leave the caps so people actually read it.

It is quite troubling to read how many people are saying that wiping in CWM will erase the SD card.
It 100% DOES NOT. I have wiped in CWM dozens of times already. I can not say the same for Factory Reset in Android...but in CWM wiping data DOES NOT wipe your SD.

[Q] how to save to external sd

is there a way to change where the pictures and app data are stored on my external sd instead of the internal sd cause being a rom flasher i dont want to back up my photo every time its just a pain

well not sure about apps. but if you go into your camera settings you can select sd instead of phone. btw switching roms shouldn't delete pics. I know mine doesnt delete it.

ok cool thanks ill try that.
it does when u have to wipe all data

huh really? you mean wipe all like wiping your internal? ill definately have to check that out. I thought everything in your internal sd card was still intact when you use calkulins format all or when you do it manually like wipe cache dalvik and wiping your data/factory reset. just did it and my pics sitting on my internal sd were untouched. weird its happening to you tho.

maybe it was the format system in mounts and storage cause i was following qbkings video on how to install the tnz blend rom and maybe thats what did it

oh ok gotcha. lol I didn't know how you were doing it. good to know tho thanks man.

completely wipe the phone?

Just wondering, as i'm probably selling my Galaxy S3 soon... what's the easiest way to completely wipe everything off the phone? Pictures, apps, documents.... everything? Will re-install a custom ROM after wiping.... just want to make sure all personal data is off the phone.

I imagine using twrp would be the best way. Not sure if there is another alternative. Maybe odin.
First before wiping system you may want to wipe internal storage (after backing up your internal storage to your computer or something first of course). Then boot up your current system and transfer a rom you want to install to your internal storage. Then reboot to twrp and wipe system, factory reset, cache and dalvik. Then install a rom fresh and then it should be ready to go. This is what I do after selling a device, before shipping to a customer.

.... wouldn't copying a custom ROM to the internal storage BEFORE wiping System and everything also erase the custom ROM i just transferred to the device?
And i mean wiping EVERYTHING. basically as if the phone was just taken out of the box, and unlocked, rooted, and custom ROM installed. No left over files whatsoever. Don't think wiping just System does that, does it? Wouldn't i do the "Wipe Internal Storage" or something like that? Think that's about what i did on my Motorola Atrix when i sold that.

* edit looking into the wiping system part to see exactly what it erases.
Wiping system, factory reset, cache and dalvik should erase everything except storage. You could wipe internal storage after you freshly install a ROM. But hopefully there are no errors, because you will have no files on storage if something had went wrong during installation. I would also have a ROM file on an external sdcard that you could plug in if you needed to.
You will probably want to leave one ROM file on the device for the person you are selling it to, just incase.

Well, I am selling it with the 8GB Micro-SD card anyway, since i've got no use for it with the Nexus 5. And i believe that's what i did with the Atrix. Wiped storage/system/factory reset/cache. Pretty much everything that made sense to wipe.... and just kept the ROM on the SD card out of the phone, just to make sure i didn't accidentally wipe that somehow.
And i'll probably just do what i usually end up doing for stuff like this. Wipe everything, install the ROM and make sure it boots, and just shut it off when it comes to the initial setup screen.

phone memory still almost full after wipe

I recently switched roms from Carbon to CM11 trying to find a rom where the bluetooth works. I did the factory reset and wiped everything but even before putting apps back on phone I only had about 2gb of space left. I thought factory reset would format and clean out the phone.

i believe you have to select option 'format sd card' to clean it out. make sure you have a backup of important stuff, i.e. pics, music, etc. or else move to external sdcard. make sure you have a ROM to flash afterwards also.!
err on the side of kindness

Even when I dona full clean install with a wipe of everything, my back up folders remain with a lot of space used in them, especially if you have a large titanium back up folder

Format sd option I assumed was for the external sd card. I can try re-flashing the rom doing that. As long as it doesn't wipe the external I'm good!
Is there a fix for bluetooth on 4.4.4?

think is option to format either. i dont use bluetooth but you could check your ROMs thread to see if others are having it and if theres a fix.

Thanks for the info. I'll check the cm thread. I know nobody seems to respond in the carbon thread when I asked about it. I really like the carbon better than the cm11. I work outside and live with the bluetooth headset all day long. It socks that I cannot seem to get it working.

When you wipe data its formating the /data partition if you want to wipe internal you have to choose to wipe internal SD card

Got it, on my next flash it is!

Just to clarify because some of the posts seem a little confusing. ..
If you factory reset from custom recovery it will preserve the internal sdcard. To wipe that you have to choose the format /data option. Wiping sd card I believe is for the external sd only. Ive never used that option though so I suppose I could be a bit off on that point.
Factory resetting from stock recovery formats the entire /data partition. There is no way to preserve the internal sdcard in this case.
