Friends I am back to stock ICS after a long time and my laptop is not detecting my phone's storage. How to mount internal SD?
what is the os of your laptop? some os doesn't support mtp connections
My bad, forgot to uncheck 'USB Debugging'.........everything fine now.

At some point in the recent past, I started seeing only the SD card whenever I connected my phone for USB mass storage.
I thought it was just a fluke or messed up PC drivers or something, but now it looks like my internal srtorage is straight up gone.
I've re-flashed CM10 and have even rolled back to an older build, but it's still gone. All my music was on it, and the music is nowhere to be found.
It's gone even when I mount USB storage from within CWM recovery.
Apparently there is "internal storage" field in the Storage section of Settings (other than the one for apps), but it just says 10.69GB free of 10.69GB.
I went into Root Explorer to look for the /mnt/emmc directory; it's just gone. No trace.
How did I manage to screw this up?
EDIT: Apparently a nandroid backup still successfully wrote to the internal storage. It just doesn't seem to want to mount in the OS or when connected as mass storage...
I am unable to access/see the internal SD when I plug in to USB and choose USB Mass Storage option. I can access the external SD, but internal now refuses to mount. I rooted for the first time about a month ago and have not had the time to do anything further beyond a Titanium backup. Everything is present and working properly, I can use a file explorer to see the internal memory, but cannot access or manipulate via PC. My Computer presents two drives (internal and Ext SD), but clicking on the one that should be internal gets me the popup "please insert disc into drive..." This did not happen at the same time as root, have been rooted several weeks before problem appeared.
I've tested both CM v10.1 and ARHD v18.
Neither has a "plain USB storage mode" for the internal/external storage.
I mean, I would expect the phone to behave like a "usual" USB memory stick when plugged into my PC.
Instead I only get MTP and PTP modes which don't work well with my Linux boxes (my house has no windows at all!)
Any advice?

Theres currently no way to use the internal memory as a USB device since it uses the MTP protocol.
However you can use your external SD as a usb device using SGS3 Easy UMS. Check here http://forum.xda-developers.com/showthread.php?t=1711009
Search on Google, it's a design of jelly bean, decided by Google, to secure internal emmc and to be able to use dynamically all the internal space for data. Internal sdcard is in fact a folder in data folder virtually mounted as a device by android os. On the contrary before that internal sdcard was a separate partition.
That explain why it can't be mounted as usb mass storage, which is only possible with plain partitions.
There are ways to bypass it either with the above mentioned app, either with a tweaked kernel.
While I can understand the limitation for the internal storage, I don't really get the point with the external storage.
The limit just makes things harder: I could eject the uSD and push it into a reader...
By the way, which kernel supports USB storage mode for whatever storage?
I run cm 9 / cm 10.1 .
Thanks.
You can use Easy UMS to mount the external card in mass storage mode
Yes. But why needing an extra app when it is a built-in feature with other (cheaper) phones and ROM?
Why, if the recovery (PhilZ Touch 3) CAN DO IT?
This was my original question, though.
Sup guys.
I've installed the Verizon JB Leak following the tutorials around XDA.
Everything works great, booting fine...but i can't mount my internal storage.
I'm starting to have trouble for installing some apps - it just won't allow me to install.
Also, when i connect it to the computer like an USB Mass Storage, it keeps asking me to format it.
Is there anything i can do ? Maybe manually mounting ?
Thanks in advance.
Nevermind.
Formatted and fixed.
]Now i can't mount my SD card LOL (when connecting to the computer)
Hi
I've been having problems with my USB mass storage mode. It turns on fine, and I can transfer whatever files I want, but after I'm done and I turn off the USB storage mode, the ROM crashes. I've ejected the phone and the SD card from the computer before switching off the USB storage, but it crashes still.
Is this a known issue or there's something wrong with my phone / me?
Mass storage is been buggy for all kexec based ROMs for Razrs.
I suggest use AirDroid.
