[Q] Nexus 10 and USB OTG - Nexus 10 Q&A, Help & Troubleshooting

I've been seeing some blog posts about better thumb drive support being built into 5.0. Does this mean that I no longer need to use stickmount after I upgrade and can just browse my thumb drive (via OTG) withing my file explorer app of choice?

If I remember tonight I'll take a look, although I do have superuser (via cfar) installed.
Edit: ok, EStrong file explorer doesn't seem to like my USB keys not matter how they're formatted - despite stating that it supports Fat32 and NTFS - but it's perfectly happy with my SD card in Fat32 format. This is using Lollipop.

[Q] Question re: USB Disk drive

OK, I just downloaded and installed the 3.1 update, running stock OS.
CONFIG
I have a 32GB A500 which I assume is main memory / SSD. I also added a 32GB micro SDHC chip in it, and for testing, an 8GB thumb drive in the large USB port. They all show up in system Settings,
When I have had the A500 connected via the mini-USB port, the memory / SSD shows up, but not the sdhc card, and not a thumb drive if i plug that in (when I look at it as an extended drive)
Some applications can see memory / SSD, and the micro SDHC chip. For example, ES File Explorer has a tab which cycles between the memory / SSD file system, and that on the SHDC chip. It doesn't include USB storage.
QUESTION
First, I'd like to confirm that something (anything) can read the USB file system.
Next, I am looking for a utility that would allow me to see all three file systems: main/SSD, SDHC, and USB, and move things back and forth between them, and to/from my PC as well. Recommendations?
As far as I know there is nothing that will allow you to read the 'external' drives from PC. This was supposed to be fixed in 3.1 (just another thing borked..), so go figure when or IF it'll ever be available.
Incidentally, my 2.2 Archos 101 did all that perfectly, but the new android versions won't, funny eh?
Assuming he has the proper drivers installed, what if he went micro usb connected to pc and thumb drive in tablet. He could read/transfer files from thumb to tablet and have the pc read/transfer to/from the tablet. If that makes sense or helps.
Get a file explorer and go to the mnt directory. the internal, external and usb storage are all there.
I guess I'd be happy with an answer to the first question below, happier with an answer to the second:
1. Is there any app, running on the tablet, which will allow me to see the file system on a USB thumbdrive? Which one. It's odd to me that I can see the drive, apparently properly formed, in the tablet "system settings" app, but (so far) haven't seen how to get at it myself, and haven't found an app which access it either.
2. Is there an application, running on the PC, or an app running on the tablet, which let's me see the file systems on tablet, tablet's sdhc chip, thumb drive and PC storage in a unified way, so I can move things around without unplugging stuff? That is harder, but one of those networked file access utilities might do it.

1) I use Root Explorer and I can see the USB Storage in the MNT directory in the root of the device.
2) from the PC, adb i assume, but i've never done this. For network, try Samba server - https://market.android.com/details?id=com.funkyfresh.samba&feature=search_result.

To answer the first one, no, there is no application to read the external data drives.
As for the second, to transfer files between these, you need to get a file explorer like Root Explorer. The multimedia apps have the ability to access the external data drives so if you want to store music and/or movies on them, you do not have to use up your internal memory.
Hope that answered your question.
Does 3.1 add ntfs support??....if not can I make it support without rooting my tab??

I use Astro, in Astro I see them all. Home, Up and you'll see all the storage areas.
Astro will allow you to move things back and forth between SD, USB and Internal storage.
Nothing that I know of, will allow you to directly view your USB or MicroSD using your PC, by directly I mean through the microusb connection.
There's an app called Wifi File Explorer Pro which may allow you to see them on the PC however I'm not certain as I never used it extensively and may be more trouble than it's worth as you'll have to open a port in your router for it to work properly.
Hope this helps.
Any file manager can access /mnt/external_sd and /mnt/usb_storage.
Drive mount or USB mount all can mount ntfs drives. Must be rooted.
Can only access internal memory front PC. End of story until google/Acer fixes it.

I am on 3.1 ota and I wanted to root it for ntfs support.....but don't want to void my warranty.....(weather here is too humid so generally all electronic devices don't work or something or the other happens to them)...so I will unroot later to claim my warranty.....what else can I do with root.....(no custom roms..).......

Any file system application (ASTRO, Root Explorer) can access all storage devices in your system. The location for the storage devices is /mnt.
Note that the /mnt/sdcard directory is actually a FUSE mount of /data/local
The directories related to storage are:
/mnt/sdcard - a FUSE image of /data/local. This is internal storage.
/mnt/external_sd - The microSD card. Must be FAT32.
/mnt/usb_drive - A USB drive of some sorts...can be a thumb drive or a hard drive. Not sure about 3.1, but 3.0.1 needed this drive to be FAT32.
2. Is there an application, running on the PC, or an app running on the tablet, which let's me see the file systems on tablet, tablet's sdhc chip, thumb drive and PC storage in a unified way, so I can move things around without unplugging stuff?

Answer...other than ADB, no (until Acer fixes that). When you mount your tablet to your PC, you are connecting to a FUSE partition, which is an image of /data/local. You can transfer files between /data/local (via FUSE partition) and your PC. Unfortunately, because you are accessing a FUSE partition, you are restricted to only /data/local (so you can't get to /mnt). ADB is a known exception (as it uses USB Debugging to access the tablet), but that isn't graphical at all (all command line, which means it is a lot of typing).
op mentioned ES file explorer
Use it myself - as I really like the interface and the LAN access works great for me.
You can see all your storage devices from es explorer
/mnt/sdcard = internal memory
/mnt/external_sd = microsd card
/mnt/USB_drive = USB based storage device
If you want to mount ntfs you need to root.

Native USB storage mount?

Thoughts on whether or not it'll happen? Although given the Nexus 6P will probably have the USB type-C port, we'd need all-new OTG cables to even take advantage of it...
Nexus 5 with the latest Marshmallow preview can do it, plug in the flash drive and a notification pops up "Kingston USB drive|For transferring photos and media" click it and it brings up the file explorer and can access and copy things to internal storage.
I'd say its a safe bet that any newer phone will be able to do it
"Native" as in it shows up under storage in Settings and actually mounts to /storage/usbstorage. I have to use ES File Explorer on my Nexus 9, but I had the thought that with Marshmallow's new storage handling something might be different on the new Nexii.
edit: Also so other apps with the WRITE_EXTERNAL_STORAGE permission can access the data on it.
otg is supported.
But not every app can access it, it's google's design
I bought this Kingston DataTraveler 64 GB Micro Duo Type C USB 3.1 Gen 1/USB 3.0 Flash Drive, Just plugs right into the jack of the 6p. You can view files on it with Googles file browser, but cant mount it so other apps can see it. I cant figure out how to view the usb drive through esfile explorer, root explorer. Also just rooted to see if that would work, but no go, only googles file browser.
Any Ideas?

I use the (root) app stickmount. You might also want to try ES file explorer (yes, I know that the new version have many unpleasant features...).

marshmallow 6.0 and USB Fat32 ONLY ! no exfat or NTFS support

Hello.
I use my nexus player as Kodi player
I have upgraded to android 6.0.
When y connect a USB memory stick formated in NTFS or ExFAT, android didnt mount the file system, I can only format the USB stick.
With Fat32 usb memory stick, Android mount the file system and I can access the files (/STORAGE/XXXXX).
But with the fat32 system, i can't copy file > 4 Go (big MKV video) on the memory stick (fat32 limitation).
Can you help me ?
Thanks, and sorry for my bad english.
I have run into the same issue. Unfortunately it doesn't seem like anyone has built an ASOP Marshmallow 6.0 kernel with ntfs or exfat enabled. One option is to downgrade to 5.1.1 and use Kernelfox's kernel and another option possibly is to be install CM 12.1 rom.
I found this issue annoying as well... I finally just plugged the USB stick into my router and load my large .mkv files from there... but you'd think android would support ntfs sticks... oh well.
root
install stickmount
that is the only way i know for sure to do it. i have an external drive connected directly and play large 20gb plus mkv rips doing it this way. there is a file you must install on the root but just read all the instructions in the stickmount description in the store

Does this work on 6.0? I currently have two 1TB drives on 5.1.1. I couldn't get them to work on 6.0 when it first came out.

yes, it definitely works on 6.0
you need to make sure you follow the instructions for the file that needs to be installed with stickmount. all the instructions are in the stickmount description in the store.

Yes sir. I installed 6.0.1, rooted and installed Stickmount. Everything works. The only thing different from Android 5.1 is when I plug my hard drives in, I have to go into ES File Explorer and unmount both drives, because of Android 6.0's built in OTG support. Then I can go into Stickmount and mount the drives as usual. It adds an extra step, but I think it's worth it because Android 6.0 looks much smoother than 5.1 did.
Edit: I've also found out in the past that things go smoother if you unmount drives in stickmount before you take out or plug in another drive.
Edit2: Also, my drives are NTFS formatted. Stickmount asks you to download 2 files when you first open it. I suspect these are the NTFS and EXFAT compatibility files, because I've never had a problem with NTFS drives.

Is there anyway to automate the unmount/mount? I'll be stetting this up for someone else, and don't want to redo it everytime he resets the device.

Not that I know of
I know that it's too much later but after suffering the inability to mount neither exFAT nor NTFS in stock MM in my Idol 3, i leave the program that mounts successfully both file systems, https://play.google.com/store/apps/details?id=com.paragon.tcplugins_ntfs_ro
It's weird but in LP i could mount exFAT file systems without any external program and after upgrading to MM it's not possible, sometimes AOSP gets worse. Anyway, before that i used to make use of this app to mount NTFS and still work in MM, https://play.google.com/store/apps/details?id=com.paragon.mounter

Hard drive shown as corrupt

Guys I am having a problem with my HP 1 TB hard drive. When I plug it in my phone using otg there is a notification saying that "your hp hard drive is corrupt, tap to fix " which takes me to a format manu.
Of all the file managers available , only es file explorer is able to read the contents but writing operations are not allowed.
The otg cable is fine because I can use all my USB drives without any problems
The HDD itself is not corrupt as I can read/write on it using my PC/laptop
Note: when I first bought the HDD it was working normally on my phone ( it was blank back then) but then I had to format it to FAT32 for it to work with my PlayStation 3, after then I again formatted it to NTFS and transferred around 200 GB of movie and series in it and here I am.
Any help is appreciated

I had the same issue w/SanDisk 128 dual USB. Download 2Tware's Fat32Format (CNET has it) or a similar, third-party app and format the drive in FAT32. Hopefully, that'll fix your issue as it did mine.

Fire tv 3 USB OTG

I've had the AFTV 3 for a couple of months but only just tried hooking up a usb flash drive. I tried through the OTG + ethernet usb hub and I tried it with just a OTG cable. It doesn't mount the usb drive.
I'm sure I have it hooked up right. I formatted Fat 32 (even though it should do that automatically). It's getting power because the light on the Flash drive turns on.
I'm wondering if the update I got on May 15th removed the USB storage option?
Any help is appreciated. Thanks!
The Fire TV 3 has never mounted USB drives in a way that all apps can access files on the drive. Your only option is to use an app that can mount the drive itself. Two such apps are ES File Explorer and Total Commander with a mounting addon. Once those apps mount the drive, you'll then be able to select a file and choose a different app to open the file. Some more info here: http://www.aftvnews.com/amazon-fire...rives-keyboards-mice-flirc-ethernet-hubs-etc/

Thanks Elias!
I should've read the full article.
For now is there still no way to mount usb drive permanently?
Looks like Gen 3 is more protected then older versions, but maybe we can execute commands like "mount" in some way? (just my naive guess)

Sadly not, a Fire TV 3 is only suitable for "paying" apps (Prime, Netflix, etc.), and is much more limited than its predecessors (similar to Apple TV). That's why neither the 3-series nor the Cube is an option for me. I don't like closed systems!
Why is a NAS not an option?
