[N7/CM10.1.2] Mount NTFS USB stick r/w ??? - Nexus 7 Q&A, Help & Troubleshooting

I used to mount my NTFS-formatted USB stick r/w on my stock N7 using an app called UTG Helper.
Since upgrading to CM 10.1.2, the system mounts my USB stick r/o before UTG helper has a chance to kick in.
Root Explorer offers me a "MOUNT R/W" button, but it does not work.
Any suggestions how I can get my USB stick mounted read/write?
Thanks

How can I create a symlink or bind for USB in the sdcard directory?

I have a rooted a500 and was able to bind the external SD card to a folder in the sdcard directory using "mount -o /mnt/external_sd /mnt/sdcard/external-sd". I was able to do the same with a fat32 USB thumb drive but it breaks as soon as I unplug the USB.
Is there any way to create a link or bind the USB on a more permanent basis? Essentially, I want to be able to quickly get to files on the drive in estrongs file manager without having to change to default directory from sdcard.
Thanks in advance for any assistance.

Of course, as soon as I posted this, inspiration struck and I simply changed the mount point.
If anyone else wants to do this, you need to edit /etc/vold.fstab to point the the new mount locations. I just changed the mount point to the new folders I created in sdcard and rebooted. Also did this for the external SD card so that I don't have to rebind it each time I reboot.

EXT4 usb drive mount

I have some problems with my ext4 usb drive.
I can use in recovery (I can read/write), and I can use with MultiROM also, but in the system I can't use.
Actually I'm using the stickmount, (and I placed the necessary files mount.exfat-fuse root of SD card) when I plug my USB drive, it looks like properly mount, but the all file explorer say empty drive....

I have an ext4 formated USB thumb drive; I also cannot see it (running android 4.2.1) with any of the file explorers I use. I also have installed multirom and use the ext4 usb stick for Ubuntu.
I have an app called "USB OTG Helper" which helps mount stuff plugged into the OTG cable, and the file systems it mounts appear under /storage/UsbOtgDrives/, but the ext4 system does not seem to be mounted. If I plug a vFAT-formated usb stick into the OTG cable, it appears under /storage/UsbOtgDrives/.
So I suspect that the problem is that Android does not understand extX formats...there are probably some apps out there that will enable that but I have not seen them.

Actually the USB OTG Helper solve my problem...
I can read and write my ext4 usb drive.

Does the Nexus 7 even allow USB OTG flash drives when booted?

Not mounting verbatim external hdd otg

Hi, I'm trying to mount a external hdd on my nexus 7 but in es file esplorer the folder is empty.
I'm stock 4.2.2 rooted, using stickmount (tried others app with no success)
Tried ntfs and fat32..
I can mount other drives but the verbatim is not accessible.
The drive has it's own power.
So i want to know if there is a workaround for this
Or not all the drives can work on the nexus 7 ?
Will a kernel or custom rom can make it work?
Tried apps especially for ntfs mounting , one see the drive but will not mount it.
Anyway I have ntsf file for stickmount, it should make it.
As I can see, it is just not mounting, stickmount say it is but not really.
Is there a way to force mount?
Or app that could bring more success?
Oh so now, with nexus media importer i can acess my disk read only mode.
Better than nothing
Still accepting ideas.

[Q] [PA 3.99] Enable USB mass storage instead of MTP?

Hello,
Is there a way to enable USB Mass Storage on Paranoid Android 3.99? I know it will supposedly prevent the phone from accessing the virtual sdcard partition while plugged to a computer, but this would be a minor annoyance in comparison to the complete pain in the ass that is MTP:
1. Transfers are slow and unreliable (stopping unexpectedly...)
2. It can only perform one task at a time (can't browse folders while copying files for example)
3. Poor implementation on Windows (Explorer keeps asking stupid questions like "are you sure this type of file will be recognized by your device?")
4. Computers with restricted user rights prevent MTP devices from installing.
and so on...
I've tried the following trick:
Code:
su
setprop persist.sys.usb.config mass_storage
reboot
But it didn't work.
Please help. I know it may require a lot of effort but I don't care: MTP is really too much of an annoyance.
No you cannot mount the sdcard as usb mass storage
In order to do that the sdcard has to be it's own fat partition.
On the nexus 4 it is part of the data partition and the folder is fused to the sdcard mount point.
Basically meaning that you can't mount /sdcard because it's not able to be mounted as it's not actually a partition.
And secondly the format is ext4 so even if you could mount it, it would not be readable by Windows

How would Android react if /sdcard was actually a separate FAT32 partition mounted in its usual location?

According to this article that should work.

It would work. However doing that is not an easy task.
It would require;
1. Changing the partition table on the phone.
2. Rewriting the bootloader (not 100% sure on this one, but it would be needed to flash any rom from the bootloader (stock)).
3. Rewriting a recovery to support the new partition.
4. Finally making the changes to the rom to support ums mounting.

It looks like this would be something in relatively high demand. So I've been trying to get Android/vold to mount and recognize a vfat image as an sdcard but haven't had any success. It might be easier to work with if I killed off the fuse mount to start, but I'm not really looking to do that right now. Manually mounting the image isn't a problem (busybox mount or using losetup first to establish the loop) but without Android recognizing it, there's no chance of being able to use usb mass storage.
Of course the inherent issue will then be "lost" space with regards to the internal storage, since it'd be dedicated to the "sdcard". It seems most users would be fine with this, setting aside a gig or two.
