USB OTG + stickmount - Nexus 7 Q&A, Help & Troubleshooting

I bought a brand new 64gb flash drive to use with my nexus 7 but while it works fine initially in windows it then shows up on the n7 as 'damaged usb stick'. Then when i plug it back in pc it requests reformatting.
I have successfully been using a 4gb flash drive on the n7 with stickmount though.
So it it possible my brand new flash drive is corrupt or are there limitations with n7 and stick mount that make it very 'hit and miss'?
Anyone else had similar issues?

I would verify the OTG cable works by trying a controller or another flash drive possibly, if you haven't already.
I had issues with getting my Sandisk flash drive to appear at first, but I got it eventually.
i also plan to buy a sandisk pendrive
and otg cable fro ebay ~
but dunno it working or nt
Do you have stickmount? If so when download stickmount make sure you go into the app and mount your chip. Should work

Using Seagate 1tb on Nexus 7

So I'm going on a long trip next weekend where I could potentially lose data from my phone (hot spot) so I purchased a 1tb Seagate Back Up Plus to use. Out of the box it isn't recognized by my Galaxy Nexus (Nexus 7 isn't rooted yet) via USB OTG and I have been trying every format/app in the book but it has yet to see it. Any suggestions?
Does your kernel support NTFS, exFAT, or just Fat32 ? Might need a new kernel to read bigger file systems.

OP mentioned that Nexus 7 is NOT rooted...
@OP.
firstly Nexus 7 is NOT galaxy Nexus...
2nd... to support that HDD 1TB
(just tried it with my Rooted Nexus 7, 1TB 3.0USB HDD, it works)
you need a rooted device with any Kernel that supports transfer via OTG
(Most Kernel support it)
Way I read the OP, he has a GNex and a Nexus 7

Well He used Round brackets for the Nexus 7...
Here in forums brackets are usually used to support the sentence before it...
K I have a rooted Nexus 7 now with a kernal that supports FAT32 etc. It will recognize my hard drive using stick mount. I use ES File Explorer to go and play an mp4 movie on it and the movie isnt showing up. Neither is the folder I created it's just empty.

[Q] USB OTG question

I have the international version of the LG G2 32gb. Stock rooted with exposed framework, one or two navbar/statusbar modules installed.
I have tried a small 4gb usb drive and the G2 recognises it just fine. I have nothing bigger except for an old (perfectly working) 100gb usb external hard disk drive ntfs format. it doesn't rely on any power. USB cable from PC powers it just fine.
So when I connect this drive via USB OTG, my G2 simply doesn't see it. I've waited more than half hour to see if it is performing a media scan silently but it still doesn't show on any of my file explorers such solid and root explorer and stock one ofcourse.
Does anyone have any ideas?
Is it because it is an external hdd?
Is it because the phone can't power it on its own?
Is it that it can read only smaller cards less than 100gb? I don't have access to anything else to test.
Is USB OTG supported in aosp roms like pac man?
Thanks guys.

NTFS
That's your problem friend... Format it to FAT32 or root and use this
Cheers!
Really? Wow, I'm gonna have to transfer all those files from the hard drive first and then format right? I hope my G2 would recognise it then. I'll post an update soon as I can get my hands on another HDD to back up to before format.
Thanks.

The only thing is, my other small USB drive which did work via USB OTG is also NTFS format. Why would this work and not the larger capacity external HDD?

Are you 100% certain the other one is NTFS?
Android is not NTFS compatible out of the box (unless rooted).
Cheers!
Yes I'm sure. The 4gb USB stick that works over otg cable is actually what I used to create a quick recovery drive of my win8 laptop as soon as I unboxed it. Win8 requires the flash drive to be NTFS for the recovery image to be created. So I did as it asked and formated and it produced the recovery drive on it.
I now connect it to my G2 and it recognises the flash drive and it shows the contents as recovery files for windows.

Yes, it should work. Do you know what the flash drive is formatted as? If you plug it into your computer (I'm assuming Windows) and go to File Explorer>Your Flash Drive>Right Click the image>Properties>File System
Tell us what it says. Sorry if my directions aren't the best, but you can just instructions on how to find file system type.
I tried two usb flash, the first didn't work and the second worked.
My 32gig patriot works just fine.

My 32GB Kingston does work over OTG...
Cheers!
Your question was answered in your original thread, yes it does. Try a different brand.

I successfully connected my 500 GB external hard drive to my phone with a $2 OTG cable.
Had to use Paragon NTFS to be able to access the drive, though (it's formatted to NTFS)
And it works with a 64gb ntfs formatted drive too.

For NTFS drives, the better and more convenient solution is to use Stickmount.
Just put the ntfs-3g module (see playstore page of Stickmount for link) in /sdcard.
I use a 1TB NTFS external harddisk without own power supply (!) with the G2, and it works without a hitch! This phone is able to do what my tablets can't! Thumbs Up!
My Sandisk Extreme 32GB USB 3.0 also works perfectly on my G2 (D802)
to be more clear.
using twrp 2.6.3.3 and AOKP 4.3
will read and write on 32 or 64 GB flash drive formatted either fat32 or NTFS. :good:
using TWRP 2.6.3.3 and STOCK AT&T 4.2.2 rooted
will read and write 32 GB fat32 flash drive :good:
will not mount 32 or 64 GB NTFS flash drive
I havent had any issues with OTG using thumb drives or micro sd...of any size...either works just fine.

otg on lollipop?

hi, is it possible to read usb like this on nexus 4 with lollipop?
http://www.conrad.it/medias/global/ce/3000_3999/3400/3450/3453/752527_LB_00_FB.EPS_1000.jpg
Unfortunately no, USB OTG is possible with certain custom kernels, however external power must be supplied to the USB device as no power can be transferred through the nexus 4's USB port to the USB unit.
You need the following-
1. A OTG cable with external power supply
2. A custom kernel that supports OTG (Unleashed kernel does)
3. Chainfires USB stick mount app.
Hi
I am trying to use flash drive on nexus 4 I have the otg y cable and it is providing power to both flash drive and phone but the flash drive is not mounting and doesn't show anywhere on phone . And chain fire always gives this error whether flash drive is connected or not .
Any help ?
Do you have a compatible kernel?

Yes I have flashed unleashed kernel.
Have you tried freshly formatting the drive?

Yes I did formatted it couple of times and it is working fine on my laptop.
I am ordering a new otg y cable maybe the problem is with the cable.

You need to active OTG from an app like Synapse, I've manage to connect to a USB key but I've some issues with the HDD
