Made some progress with USB storage without the use of an app. Setup so far is really simple. Add a line to /system/etc/vold.fstab that looks like this:
dev_mount usbdrive /mnt/usbdrive auto /devices/platform/tegra-ehci.0
Still need work on getting the external storage managed by the system.
WARNING:
This is just a first step and with no way to unmount using Android's storage manager you may corrupt your external storage.

Does that mean I can back up and restore stuff via otg as if it were my external sd card?

Wow I JUST got my OTG yesterday. Fantastic timing.
what this means... hopefully
As it stands now, adding this line will cause your N7 to automount a usb drive to /usbdrive. You will see "preparing usb storage" in the notification bar and your file explorer of choice will see the data in /usbdrive. Unmounting is an issue at this point. I hope to fix that in a few days when I get the time.

I believe this works on the N7 I am waiting on my cable to test. I realize you want to do it without a app but the syntax should be close.

Correct me if I'm wrong but I believe that CM10 already has USB Storage OTG built into it with the last few nightlies.

a day late and a dollar...
Haven't been following the cm10 builds. Still gonna push forward for the exercise.
People who don't run CM10, can use this method. Would be cool if unmount is done.
Guys, quick question as I'm receiving my N7 tonight, the usb stick format can be ntfs? Or only fat32? Thanks
EDIT: saw from other thread, ntfs seems ok as well. i already got the tab and will start unlock and root.

Just wanted to confirm that stickmount works well with the N7.
I have it installed and I've used it on two different usb drives.
A 32GB PNY USB2.0 Flash Drive Stick
And an 8GB uSD card inserted into an elago II USB Reader.
Both worked without any issues.
However, I'm still intrigued by a method to get usb mass storage support natively w/o an app
That does it...I give in! I gotta try the twrp recovery. Feel like I just decided to cheat on my girlfriend.

I saw a post about it somewhere around here. Referenced Amazon.uk, the title was USB otg that work and ones that don't I believe. Google can probably get it. If I wasn't using the app I would hook you up.

Can I ask, does this support NTFS r/w? or r/o.
Everything I've tried, aside from USB OTG Helper--including a CM10 kang rom that claimed to support ntfs OTG--will only mount r/o.
Including the command $ mount -t ntfs /dev/block/sda1 /usbdisk. I guess it's the ntfs driver or something? but it will only mount r/o. Even $ mount -o remount,rw /dev/block/sda1 /usbdisk does not work, it still is ro.

I'm rooted and running cm9 stable. For some reason after flashing cm9 no file manager is working. Anyone else having this issue? Is it because I'm rooted?
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
What file managers have you tried? What is the exact error? What happens when you try?
I've tried astro, es, root explorer. And no error pops up its just I can't read any files like I use to on stock. When I got to my external sd there's nothing there. And I know it's there because everything is have on my sd card is on my phone. Very annoying. I've tried almost all file managers. I'm running cm9.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
Can you verify that both /sdcard and /emmc are empty as per the file managers? Can you access the data (lets say pictures) via the gallery app?
Yes I have music, pictures, and video on sd and I can access them all on the gallery/media player

Please verify that /emmc and /sdcard mounting points are empty via file manager of choice.
Also what this feels like to me is that you are not aware of the way CM9 mounts your Internal/External SD cards.
Internal Memory: /emmc
External SD: /sdcard
Now you will have a folder called "external_SD" on your memory card, this is a left over from stock and will not function as before.

I did not that all the files did that emmc somewhere. So I can view my external and internal now?
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
Not sure what you're trying to say but /emmc is the internal memory and /sdcard is external SD card.
You probably are not seeing your files because they are all in the /emmc "folder" (which used to be called sdcard when you were on a stock rom)
In ES File Explorer go to "Settings" > "Root Settings“ and mark the "Up to Root" option.
Exit settings you should see "/sdcard" at the top of the app.
Press the "UP" button on the toolbar, it will now display "/" at the top of the app.
Congratulations, you have made it to the very top level of your devices file system.
You will find "emmc" and "sdcard" which are your internal and external "memory card" locations.
Shazam.
If for any reason you don't see this, attach a screen shot at each step and add them to this post.

I don't use Astro so I cannot guide you but I can say you need to get to /emmc or /sdcard. You either have to go up to the root filesystem "/" or access the "folders" directly via "/emmc" or "/sdcard" I don't know how many times I can say it.
I am currently on cm10 8/31. I tryed the new build of remjb and after flashing my imternal storage wouldnt mount. It shows 0 bytes of 0 bytes in fx file and root explorer says it is not mounted. So i restored nandroid back to the cm10 and it was mounted. Oh well its ok, i like cm10...... I tryed to take a picture a couple days later and it says i have no storage.... Now my internal isnt mounted on cm10 either. Did full wipe and reinstalled and it still wont mount. In recovery it shows up fine......... I guess what im asking is can anyone give me a terminal command the mounts the internal storage. Its just frustrating as i cant take pictures and half of my apps wont function right since they have stuff saved in android/data on the sd card.
Ps. My external works fine and mounts and shows in fx file fine....

Look at this thread for answer. I think the external you are seeing is really internal. Real external might be /emmc.

I am sure its the internal not mounted because external is both emmc and sdcard1 while sdcard0 is internal. And my external is 32gb so that helps further prove its my internal just not mounting right.

Have you checked the Storage tab under the Settings to see if there is an option to mount it there?

Not a problem! I'm glad the solution was something easy. =D
It's often easy, especially when we do so much technical tweaking, to overlook the simple answers.
Don't feel bad about it. =P
exactly the same
Hey.
I have the exact same problem, but the "mount SD" in settings won't mount it. It just goes from "calculating" back to the "mount SD" button. Frustrating! It's been worked without problems till now and i haven't installed anything or changed anything!

No it wasn't. I just had to keep hitting mount USB in storage. But I switched to an old iPhone for a while then came back to this. Got the jellybean iemi issue and odined back to stock a couple times. That seemed to fix it. No longer have the issue. Weird.
PS I am in the latest Scott cm10 (11/04 with that kernel fix flashed 11/14 I think and latest gapps) fully went to stock and followed every step precisely. If you go back to stock be sure that when you get to the step where you flash an ICS ROM be sure to boot up the ICS rom once before wiping and flashing jellybean. Not doing that step messed up my iemi again haha xP had to Odin yet again.

Let's take aside the noobish method. What would be the mount command for sdcard0 mounting anyway? So much garbage on the forum, that this simple question is impossible to find a resolution for.
Hello, I have had experience with a Nexus S and Galaxy Nexus, while skipping the Nexus 4 to try out the SG3, I have returned to the Google Experience.
I remember having partitioned the S and GS to have an Internal Memory, thus also allowing me to ADB push to its home, as well as being able to drag NDBackups to my computer.
With the Nexus 5, part one was unlock, recovery, and root. I have successfully done so, though having to mess with directories to grab SuperUser for some reason- this should not have affected /sd card.
I could not successfully adb push SU.zip/ sdcard, and
a)view /sdcard on my pc
b)install zip from SDcard and see the file, there was /0 /legacy and /oob
I have googled, I have searched to the best of my keywording abilities, and find answers on Why Nexus doesnt have sd articles, and other things like Nexus 4 and 7 results that don't help.
So if anyone would mind, giving me instructions to create or open the partition, I would appreciate it.
You need to be booted into recovery first. Then mount /sdcard from the recovery menu.
If you can't mount /sdcard, mount /data and push to /data/media/0

UI didn't get a mount /sdcard option at all to touch or select, which is strange. I did however download clockword MLD and found an option to partition SDCard. I'm going to see if that mad a change and post back. Thanks rootsu
The push method helped a lot. Love the learning experience

Thats what I did, is there a reason I should not. During my GS3 days, my Nexus ways became rusty. Nothing bad has happened yet, not that I have noticed. BTW, yes, the mount /data helped.
Anyways, what about the CWM option to -mount USB Storage
That doesn't seem to operate. Is this how it is for the N5?

Jeez, man really? You're lucky it seems to do nothing. This is for phones with an external sdcard with small internal memory (200MB for example) where it takes the external sdcard and creates an ext partition on it. This is NOT for your phone. Please never touch this again. Lucky you didn't do harm!

Hmm then I'm very out of the loop. I've been able to access the SD card and internal memory I'm sure from cwm in the past.
I figured since my Nexus S had a /sdcard that's what the partition was for. Glad it didn't brick, but I wonder if it did anything at all? I guess I'll find out or not at all. Agian, thanks.

It probably did nothing. You would next have been asked what size partition you want to make so if that didn't happen, sounds like it simply failed

I just check it on my galaxy s3 and i can write and delete files. Maybe it needs format from my Note 10.1?
I forgot to say that if i put out from the Note and back in, then i can write and delete files but for a 1-2 minutes. After that, the problem still occur.

I think the problem start when i installed the revolution rom from the extsdcard and not the internal.
After 2 installs and the problem still persist i was suspicious and final i formated the extsdcard from recovery and thats it.
