I have the same problem. Have you solved it yet and how?

I solved it flashing the stock firmware blob in fastboot mode.

[Q] Unable to mount internal /sdcard

Hi everybody,
I've seen this question asked a few times but none of the answers worked with me.
Trying to create a second primary partition in my internal sdcard with MiniTool Partition I messed up the phone that now doesn't recognize the internal storage.
From TWRP I get the error message:
Code:
E:Unable to mount /sdcard
E:Unable to mount storage
I can mount the internal storage via TWRP and access it from windows or linux, I have even formatted it several times in FAT32 or ext3 to revert to the original situation but there's no way to make it discoverable by TWRP or by the OS.
As the recovery doesn't see it, it's impossible to flash a new rom because there's no place where to save the zip.
Can anyone please give me a suggestion ? :crying:
[solved]
I managed to access again to the sdcard by flashing the stock ROM from Nexus Root Toolkit

No Data Directory

Title says it all. a lady brought me her moto g and on the screen all it had was no command and the android with the triangle !. so i booted it in to the bootloader and installed a custom recovery. tried to mount the sd card so i could recover her data off of it and it failed to mount so i tried mounting /data and it wouldnt mount and it says /data directory doesnt exist. /system would mount and several others would mount. so my question is, is this phone f***ed or is there a way to restore the /data directory through fastboot flashing?
Thanks for your time

Try and reflash the system partition and boot into android. Then look for /data. /data might be corrupted...

Corrupt /sdcard

I tired flashing a ROM but it couldn't mount the /system so I formated everything in TWRP and tried again but this time the ZIP corrupted /data/media (/sdcard).
I'm getting E: Mount unable to find partition for path
as soon as I boot to TWRP (2.8.1.0).
I can't boot into system nor can I restore a backup. When I restore it it gets to restoring /data and fails.
I'm pretty sure /sdcard is my internal sd (because /external_sd is for the externad sdcard).

Encryption Unsuccesful

Hello!
Recently I recevied "Encryption Unseccesful" message on my phone. I tried to restore backup, but twrp says: "failed to mount /data". So, internal storage is dead. Found this. But cant find "repartition" menu in the cwm.
Questions is:
1. Do I need older versions of cwm to repartition sdcard? (If you have one, please share )
2. Is there any ways of recovering phone?
Thanks in advance!
no, just go to TWRP, Wipe, Format internal sdcard

tried this, but I think internal storage is corrupted. Is there a way to use sdcard as internal storage?
you can use sd card for apps and other stuff, but as I knoe cannot be used for system files
I made 2 partitions on sd:
4gb fat32
4gb ext4
But I cant bind /data to this ext4 partition. Can you help, please?
What i did:
With TWRP's terminal:
Code:
mount -t ext4 /dev/block/mmcblk1p2 /data
- Invalid argument (dunno why)
Code:
ln -s /dev/block/mmcblk1p2 /data
- but on phone boot i receive same "encryption unsuccesful" screen.
Edited /etc/fstab - same result.
Files and mount after reboot turn back to its previous condition.
Also installed stock ROM - same message screen.
[/QUOTE]
I got advice that i must do this things with init.d scripts. How can I do this? Already tried "xda's app2sd scripts" but they works if phone completely boots in OS.

Why not? I want only mount /data on sd without booting in OS. Other partitions like /system surprisingly work right, because i can flash ROM (stock, CM), but always receive - "cant mount /data"
