Mounting internal storage as USB mass storage - Verizon Samsung Galaxy S III

Hi Guys, is there a way to mount the galaxy s3's internal storage as a USB mass storage device? As you know, currently when you connect to the computer, there are only two options: MTP and CTP. I know there is an app that does this for the external SD Card but I need it for the internal storage.
Thanks!

I use an app called SambaDroid. Once you connect to your phone you can map it as a drive using Windows. I use SyncToy to back up my stuff regularly, and although it's a lot of steps, it works pretty well.
If anyone has found a less labor intensive method, I would love to hear it.

[Q] How to Push as mass storage device in PC?

Hello all
I bought a P6200 recently! but when I connect it to PC it doesn't mount as USB drive?
As well in settings menu I couldn't find it to set it to mass storage mode!(like my Xperia neo and other Android phones) even it doesn't have USB part
Would u help me ?
It's ridiculous that can't be done!
yup... it is ridiculous because it really cant be done...
That' s not true. After connecting my Tab Plus to PC, I got new wino opened with 2 drives. One is my MC and second Phone memory so I can copy whatever I want. Try in settings-application-development...
that is in MTP mode...
The reason is because of how the GTab 7+ uses internal/external memory.
It's impossible for Android to unmount the memory because it's constantly in use. This provides a lot of benefits for performance and application space.
However, the trade off is that unmounting the partition would cause android to crash. So you can't unmount it to let a PC mount the partition. The work around for this is Android hosting the partition as an MTP device and doing file changes by proxy for the PC.
Personally, I haven't found a situation where I needed to do something on the file system that MTP prevented me from doing. At least so far...
I too have had no problems so far transfering files using MTP but its very slow. So I've used a card reader to transfer files to the sdcard when I wanted to do a quick transfer of a larger amount of files such as mp3's.
Hard to mount the sd card as a drive for use with synctoy is one example of where mtp is inconvenient at best.

Mass Storange mode is no longer available since Android3/4 deives as there is no seperate internal SD card. All Android tabs connect with MTP mode.
I use SyncToy as well to backup the whole of /sdcard. But that's for the P1000, now I can't do the same on the P6200. All the other available options are either too slow or too cumbersome to use on a daily basis.

Has anyone tried the "Multi Mount SD-Card" app on this device? It mounts the SD card as USB mass storage without dismounting from the android system.
I found mine mounted them both only after i inserted a micro sd card into the device.

I have just installed Multi Mount SD-Card v2.12 and found that it is not compatible with the device. It's disappointing.
I would suggest setting up adb and using Android commander (it is a GUI for windows)

[Q] How to use both Internal SD and External SD

First I have to say thank you to all the developers for making many great ROM. Second, I am not good with android .
I just upgrade to hellfire sandwich and seem like whenever i choose using"internal storage" the phone will auto gray out the external SD card (8gb). When i uncheck that option, i can use the external SD card again. But I want to use the left over internal storage 5gb too... not just 1.5gb internal storage.
Is there someway to re-partition the internal storage together? or allow the phone to recognize all the partitions?
Another question is I cannot use USB mass storage anymore, that option is grayed out too, And the only option is MTP which work really slow but a bit better than PTP. I need some help because Android commander cant recognize the device and the transfer sped is pretty slow.
You should be able to access the internal storage by navigating in the file explorer of your choice to the mnt/emmc/ directory. As for the mass storagw, I don't know the answer, but I had that problem too while I was on ICS.
The best option I have found is to use cwm to add and remove things through storage. It works all the time. Since on 2.3.3 mounts where sketchy and I've never been a fan of mtp on ics this is what I've always done.
Your transfer rates are due to your SD card class. The higher the class the higher the read/write speeds.
Ics went to using mtp and ptp instead of USB mass storage. Except there's a few roms that have hacked ums in and got it to work or claim too.

Yes i can do that too, so there is no way to allow the phone using both... I want to let the phone install apps to internal, and use external as media storage.

Thank you, because i saw the option there so i just wonder if there is a way to enable it... but if it not supposed to be there then there is no help.
If you go to ../etc/ using a file explorer, you may edit vold.fstab using a text editor and change manually your SD cards mount points (dev_mount emmc "folder location" for internal SD and dev_mount sdcard "folder location" for external SD)

Ok, well in your SD Card you shoud see either _Internal SD or _External SD when you go into CWM, installing a rom partitions you SD card normally using EXT4. You can navigate to both through mnt in file manager. Normally it'll load into external. You can go back to mnt and go into internal through there. Now, you may have to unmount and remount so you have access to it. If your using hellfire 1.7 you need the updated harsh kernel to access USB storage. In 1.6, however, you shouldn't have that problem.

[Q] ANY way of mounting internal storage to PC? (for data recovery)

Hey guys.
I realize the SIMPLE answer here is probably no, but I'm in dire straits here.
I don't know how, but somehow, my xoom deleted all of my photos, now I honestly don't know if it was on my external sd or internal storage things got messed up, but I'm currently running a full deep recovery on my sd card to check there.
I'd also love to be able to do the same with the internal storage. Since they took away the USB mass storage thing, this seems 'improbable'. But I really need some of the wise wizards in here to tell me if there's ANY way - maybe an old kernel? maybe there's a way to do it with linux!? If anyone could help me, I'd let you name my first-born child
you should be able to see both the SD card and the internal card mounted when you plug in the USB cable, make sure you have the correct USB driver. Hope this helps..
yeah, the MTP protocol allows me to see it, no problems. But it needs to be mounted as mass storage device for data recovery tools to be able to get to work on it, since MTP doesn't give access to the actual file-system.

Is there a way to mount the device itself as mass storage(not sd card?)

When I try to mount the device as mass storage, it only shows up when I have an sd card inside, and without I get a message telling me to insert disk. Is there a way to mount the device itself as mass storage?
Wifi explorer pro or air droid as alternative. With total commander can make a Lan connection with windows xp/7

Settings/storage/click on 3 buttons/click on usb computer connection/choose mass storage.

He means the internal memory. Can only mount the external sdcard in mass storage mode.

...yes, i need it too. MTP is sh*t and i need mass storage for using on XP.

Correctly but the 4gb on internal sdcard i copied with total commander and Lan Plugin with Wifi. It's slower as copied in mass storage mode, but it works. On droid4 twice sdcards works in mass storage mode, photon q sh*t, after factory reset the internal memory cleared.

[Q] USB won't mount after TWRP wipe of Internal Storage + Android Secure

USB Storage and USB Debugging will not mount to Windows 7 PC or Mac
*I'm posting this thread because I have exhausted every option discussed on the internet*
One day I decided to wipe more than usual using TWRP. I wiped Internal Storage and Android Secure. Ever since then, I have not been able to mount USB to my PC. No PC computer on planet earth will recognize my skyrocket. "Unkown Device" is all I get. Every USB cable, every USB port, every PC, every Mac I have tried. I've tried every driver set, I've tried formatting my PC and reinstalling fresh samsung drivers, I've tried Kies, I've tried formatting my SD storage, I've fixed permissions and wiped everything known to Android. Odin will not detect the phone without working windows drivers and neither will SuperOneClick. I'm out of cards. Game over. Every other function of the device works just fine, and I've gotten by using my 64GB external SD card as a means to transfer files between PC and phone. Come to think, this all started when I put that 64gb SD card in my phone and tried to format it and everything else in TWRP. External SD card works, but nothing will mount.
Before I explore the final possibility that the USB plug on my phone is physically damaged, I'd like to know if anyone out there has had any problems with USB mounting as a result of TWRP wiping and/or External SD Card installation/formatting causing things to go awry.
Any help would be greatly appreciated. I will donate to anyone helps me solve the issue, as I need to be able to sell this phone with a clear conscience.
Thanks!
What version of twrp are you using. I saw another post where it wouldn't mount internal with 2.4.0.0. Seems it might be an issue with that version.

It was using 2.2.3 at the time. I feel strongly that this is an issue with formatting the internal SD card via twrp while adding an external SD card to the phone. I believe the system partition responsible for mounting the phone is corrupted. Maybe a re-partition is the solution? If I could somehow restore the system partition files. I am an avid flasher but partitioning is beyond my scope. Maybe someone can point me to a guide about partitioning.

Hey man did you ever resolve this issue? I just erased a bunch of folders on my internal SD and it won't mount anymore. I'm using a Droid4 and, of course, the problem is consistent on both ROM and stock.
I guess for now I'll have to download from my dropbox account.
Cheers
I'm on the Note 2 (N7100) and have the same issue. I formatted internal storage in TWRP. Now USB is not detected on any pc. Any updates?
