I have files on several USB flash drives. I purchased a USB to Micro USB adapter, thinking I could then access these files on my N10. I have tried it, and I can't seem to see the USB drive in the file manager. Am I missing something? Do I have to purchase all new micro USB drives? Or is the N10 incapable of this and the micro USB port is only for charging?
Get Nexus Media Manager. It will auto mount the mSD card and allow you to read from it. To be able to write to it you will need to root your device.
OK...thanks. Not what I wanted to hear, but at least I will be able to read the files. I still think this was a stoopid move on Google's part...not providing support for read/write to a USB stick. Bad enough there's no SD card. Good thing I LOVE the tablet otherwise!

Make sure your adapter is an OTG cable. OTG USB cables allow for data transfer and recognition of external devices. As mentioned above the media importer works for Read Only access. You can use Stick Mount and root your N10 for R/W access if necessary.

If this is really an issue, you can always throw on a custom ROM with OTG enabled. Then you get R/W access baked right into the OS. I believe craigacgomez's ROM and Task650's AOKP based ROM both have OTG enabled.
Thanks. I don't think I'm ready for rooting a tablet at this stage of my life. I'll live with using Box.com or another cloud solution. I'm too old to root anything! LOL

Your choice, but it's really easy with a Nexus and there are fool proof ways like mskip's Toolkit that make it a breeze. Good luck either way!
Hello! I have question. OTG will work on stock ROM with Nexus Media Importer, but I be able to only read files? Or I should flash custom ROM and kernel?
You could flash my custom boot image in the dev section and re lock, you'll need to root just long enough to copy vold.fstab to system unless someone mods the stock system image to add it, or creates a update zip you can flash with a temp recovery.
I'll look into modifying the boot image to create the vold.fstab then no rooting is necessary.

How are you "mounting"? You shouldn't use any apps or run anything, it should mount automatically, in /uskdisk or /storage/usbdisk
I've found that not all file managers will give me write access once it's mounted, depends how the FM works. ES usually gives me read-write, Root Explorer sometimes does, other times I have to click "mount r/w", Solid almost always works...
Also bare in mind, my boot image is for 4.2.1 not 4.2.2.
That said, if you don't want to flash the boot image, it's possible to do this by just editing the vold.fstab to point to a directory inside your SD card (which you always have write access to) and it will mount there (assuming you make the directory), no need to modify your boot image.
I use this way now, because I like to switch ROMs and can't be bothered modifying all the boot images. I just make a folder called "otg" in my sdcard directory and modify vold.fstab to mount there.

No problem.
Don't mount with stickmount, the whole point in my mod is so that the system auto-mounts it, which means you get global access. You can edit the vold.fstab with a text editor, if you're on 4.2.1 using my boo image, you don't need to edit it, otherwise just open it up and replace the mount location with a path on your internal storage.

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.

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.

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 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.

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.
Hi,
Just Got the 7.7 3g - so far so good. Screen is as good as they say
The extra resolution defn. helps with web browsing.
Not finding any lag really.
7.7 is just about the limit for my two handed use but i would say the original 7" was a wee bit easier to handle but something with time should become more intuitive.
Just a few issues - external sd card is somewhat limited. Might be deliberate by Samsung but does not make sense.
Normal user apps cant access to the external sdcard. Using connect bot, i checked permissions and it seems that it is mounted by the os with system permissions, where as the internal sdcard is mounted as sd_rw.
This can't be correct? The only way to copy stuff to it is to use the samsung system file explorer as it has system permissions So copy to internal first then to external - this sounds like a bug?
I have not rooted this yet - might then chown to sd_rw get rid of this ?? There is a lot of entries in the vold.fstab to make sense of. Not a hacker so just looking around. A bit too early to start soft-bricking
But I take these don't have protected bootloaders so thats why we can root ?
Video playback is v.good but I am not able to throw on a bluray m2ts file (obviously with the sd card issue) and play smoothly. I found Dice player can handle m2ts by renaming it to a ts file. It then can use hardware decoding. Still drops frames but still watchable to a certain degree. For all other files mx player is still best. I have lossy transcoded some "native" blurays clips and seems that it handle high profile h264 1080p at high bitrates very well. Hoping, formatting sd card ext3/ext4 will improve things.
On the whole very impressive device - plus more ics goodies to come soon hopefully.
I've noticed some issues with the external SD card as well. Only the stock file manager can copy files from the internal storage to the external storage. I was able to transfer files to the ext. SD via Dooblou's Wifi Explorer, though. Although that would crap out a few times.
I'm hoping that we see some new ROMs with a different file system at any rate. The 4GB limit is so 1998.

Simple solution for external sdcard write access on Android 3.2...if you're rooted
I've found a simple solution for gaining write access to the external sdcard (/mnt/sdcard2) on Android 3.2. The sdcard is mounted r/w, but the owning group is media_rw which is linked to the WRITE_MEDIA_STORAGE permission. Unfortunately, this permission was not required for access to the external sdcard prior to 3.2 so most file management utilities do not request it when they run...meaning they only have read access to the card.
The simple solution, if you're rooted, is as follows:
1. Using a root-enabled file manager, navigate to /system/etc/permissions and make sure you have mounted the file system r/w.
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission...<group gid="media_rw" />
4. Save the changes to the file.
5. Restart your tablet.
After this change, any apps that request the WRITE_EXTERNAL_STORAGE permission (which includes almost anything that access either of the sdcards) will gain group membership in both sdcard_rw AND media_rw, giving them r/w access to both sdcard filesystems.

Using downloaded apps or the stock File Manager app? Because I formatted the SD card in the Tab and nothing else can write to it. Now, I can drag and drop stuff from my computer via MTP, but that's not the same issue.
Ok, I'm trying to add the permission and it doesn't seem to save after a reboot. I'm rooted and made sure to mount that directory as R/W. After I edit platform.xml and reboot it simply reverts. Can anyone offer a more granular description to this n00b?
Thanks.
Edit: Nevermind. I edited the file on my computer and copied it over the original and am good to go.

Things must have changed as i got my P6800 recently did the upgrade from samsung and tried to copy to external sd and no problem for me. I never tried to do it pre upgrade but maybe the upgrade fixed that. Re i can copy and paste to device from my pc when its connected - to both device and sd. I can also copy using the the stock file manager from device to sd card.
No Issues here also
I recieved the tap a week ago. Now my 32GB Sandisk SD is here.
The Tap did at the first startup and using the described 12 MB Android update via internet conn.
Until now there is no issue between writing from/to SD over PC/MTP, copying between internal and external SD. Used preinstalled Filemanager and ES File Ex.
I tried it unrooted and rooted but not before the Android update.

Some people are reporting the above procedure is no more needed, however, with several apps (like Titanium backup, and a SAMBA explorer), writing to the sdcard (extstorage/.../sdcard) is still impossible (GT6800 updated to latest samsung firmware).
I have used this procedure and can state that Titanium backup works now with the SD card.
Thanks to many reading within the XDA forum, I have found this simpler procedure :
- download / install the "Root Browser Lite" app from the android market
- add write access to group and other to the following directory: /system, /system/etc, /system/etc/permissions (with root browser Lite, press on the directory name during 3 seconds to get a contextual menu allowing to change the permissions)
- add write access to group and other to the file platform.xml in /system/etc/permissions
- use the editor of "Root Browser Lite" to modify the file platform.xml as described above (you should have two <group gid= ...> lines within the WRITE_EXTERNAL_STORAGE xml block.)
- save the file. Verify that a .bak file has been created and that the date of platform.xml changed.
- remove the write access.
- Turn off the GTAB, then turn it ON.
NB: Titanium backup still reports a erronous free size on the SD card (401MB), but backups on the sdcard work.

damm, must forget something, just followed exacty all the steps

IS there a way to go into the (forgive the incorrect term) "registry" or similar, and have Android re-interpret/understand that instead of looking in "/sdcard"... it should instead look/point programs to "/mnt/sdcard/extstorages/sdcard"...
i heard that it might be called something like a "simlink" or "symbolic link"... maybe this could resolve the application installation issue to the sdcard as well as backups, transfers, etc... right now, not only do i run out of space too fast, can't install apps to the sd card, but as well, if i should run a hard reset... all my data erases! (yes, the internal "SD card" is erased in a hard reset)...
so, for all practical senses, when it says it will erase data, unless you KNOW you have copied ALL you user data to your "Real" SD Card, you will kill your data without even knowing it when you do a hard reset, even if you "thought" you were protected because "I saved my info to the SD card!"
(and yes, this was my experience today, so it's a fact.)
backup programs won't point to the sd card, (app manager, titanium, app list backup, etc)...
so unless you actively move files individually to the card (and know where to look)...
Bottom line... is there a hack/workaround on this that's not just "open up for file transfers" or is someone working on a ROM that might kill the partitioning and allow the /sdcard to actually point to a real external card?

hi forum
i would like to use the EzyKernel v1 - 23/02/2012 as in post http://forum.xda-developers.com/showthread.php?t=1513413&highlight=ezykernel
one of the prerequisites is a stock ZSKL firmware.
on the tab is/was XXKL4 AUT/CH
i successfully flashed the ZSKL2 - but that's where the nightmare started: i could not write to sdcard, busybox/superuser don't work properly, as i can't get root via su - which means to me, that there are messed up accessrights also in other places, not just the SD. the funny thing is, that i finally got the overclocking EzyKernel working, but not busybox + superuser.
does that sound familiar to anyone ?
i would really appreciate any ideas about this.

Hi perhaps some of you with a Nexus 7 can help me.
I've recently got a 16GB version but I seem to have strange problem with copying data to the device. For example, if I have a folder of photos I copy over, either over wireless or using USB MTP all the copied files on the device have had their modification dates altered to the exact time of the copy procedure - each file has a second difference between them with all the same date. The files on my computer have there correct modification dates on them.
This happens with all types of file; video, pictures, zips etc and also under Windows and OS X. This doesn't happen on my SGSII with a custom ICS ROM running 4.0.4 but I connect that via USB Mass Storage and not USB MTP.
Any ideas? Why would USB MTP alter the files in this way? It's making organisation and sorting a nightmare.
My Nexus 7 is rooted, unlocked etc using the Toolkit.
From what I understand, this is a file system issue. Fat32, which is what's used by your phone with UMS, will preserve the original timestamp, but I believe that ext (still not sure if it's ext3 or ext4), which is used by the Nexus 7, will use the file creation time as the timestamp.

Seriously? That's crazy! Is there no way to change that? Surely this is a major flaw. I have photos etc which must retain there original timestamps.
It's a problem inherent to the file system used. I believe that there might be a way to do the copying on the Nexus 7's end and use some type of command line argument to preserve the original timestamp, but this would require you to mount a storage device to the Nexus 7 via USB OTG to copy the files from. It would also require someone with Linux experience to tell you how to do it because I have almost none.

All that just to copy some photos over? No wonder people buy iPads. Guess this tab is going back to Google. No way to format it as FAT32? Also, if it's using EXT, why is the individual file size still limited to 4GB?
Nope, you can't format it to FAT32. Someone with more Linux knowledge than I have will need to answer your 4gb question (I've been wondering about it myself). Maybe someone else has another easy solution to your timestamp problem that I'm not familiar with.
Hi guys,
I'm getting tired of not being able to transfer files from my Nexus 7 [rooted] to a USB flash drive. I have Nexus Media Importer software installed, but it will only allow me to transfer files from the FlashDrive to the Tablet but not the other way...it's just plain dumb.
I usually download stuff via torrent to my Tablet and then distribute it to my friends, but when the files are over 4gb, bluetooth is way to slow and forget about the PC option, I don't have any PC to use...so don't tell me to transfer to a PC and then to the flash drive...
Any ideas?
EDIT: Also tried Stick Mount y USB Host Controller :/ NO LUCK!
Perhaps dumb questions, but since you didn't mention these details, everybody who reads your post is forced to guess.
1) Did you check the mount points (in each case) to see whether they were read-write (rw) or read-only (ro) ?
2) Should we assume that the USB stick only has a single partition, and that it is formatted in a FAT32 fashion? Or something else? What device/OS did you use to format the USB key to begin with?
If you are using any file system excepting FATx, the kernel you are using is also important - and you also failed to mention that.
BTW, I have successfully written large-ish files TO a FAT32 USB key on a OTG cable mounted via StickMount with a lightly-rooted stock N7 (essentially a stock ROM and stock kernel). "Large-ish" in this case is about 2.5 GB. (FAT filesystems are not capable of writing individual files larger than 4GB)
cheers

No dumb questions at all, I just started this thread really quick because I am at work and can't be 'on the internet' for too long.
1) I just checked and Nexus Media Importer says 'read only', I haven't seen that :/ (that's dumb)
2) The owner of the USB Stick tells me he formatted it with Windows 7 but never changed the format, it's FAT32 since he bought it. The file I attempt to transfer is 4.1Gb...
About the kernel and ROM, both stock and ROOTED.
The owner of the USB Stick tells me that he recently used it to boot Win7 and install it on a friend's PC and maybe that's why it is on 'read only'. I've checked for the usual 'lock' switch but it doesn't have one...so that must be why. Don't you think?
Also, I could never use StickMount..it just times out attempting to mount :/
EDIT: One more thing, I downloaded 'USB Host Controller' (http://forum.xda-developers.com/showthread.php?t=1468531). I attempted to mount at /mnt/sdext and many other points but none of them worked...I'm using ES file explorer to look for the mount point but it doesn't exist.

Well, the name of the app includes the word "importer". That seems to imply only one direction, but I've never used the app so I don't know.

No matter how you mount a FAT32 filesystem, you will not be able to write a file to it which is greater than 4,294,967,295 bytes in length (2^32 - 1).
Apparently there is something called "exFAT" that is intended for large flash devices, but it seems to be not ready for prime time with Android yet. (Search titles here on XDA for "exFAT"). Also, the Wikipedia page for exFAT says that it is patent-encumbered. That's a deal-breaker for Android I suspect.

Hard to say. Re-format it in windows and try again.
Thanks a lot Mr!
I'm gonna use some other app just to try to get it done, with a 'smaller' file. And regarding the USB Stick, let's just leave that behind...I can mount NTFS systems and give my friend the files in a Ext-HDD
Luckily there is always another option
Hi all, how can i enable full (read/write) ntfs support for an otg stick on my Nexus 6P?

Stickmount.
Is there a way to enable exfat.

https://play.google.com/store/apps/details?id=eu.chainfire.stickmount
Noting:
StickMount can utilize the "ntfs-3g" and "mount.exfat-fuse" binaries to add support for ntfs (untested) and exfat, but these are not included. If you place the "ntfs-3g" or "mount.exfat-fuse" files in the root of your internal storage ( /sdcard ), StickMount will automatically use them.
You can find the needed files here:

Do you unzip the file and place it in the internal storage or the otg flash drive

Yep. I saved both zip's, extracted them (no overwrites occurred), then copied to the root of my sdcard (not root of system).
Gl!

When you say sdcard are you referring to the card which is attached to otg cable. Also when I downloaded files they over write each other because both zips have the same name and same files inside I downloaded from the link on playstore.

Hey man trying to help you but you have to help yourself a little .
1. Look above, it says, "place the "ntfs-3g" or "mount.exfat-fuse" files in the root of your internal storage ( /sdcard)"
--> This means it's not needed on the external storage device you're pluggin in of course.
2. Both zips have different files. The link from the play store is the same link I posted (for your convenience) above.
3. Wrapping this up: save ntfs-3g-only.zip & fuse-exfat-exfat-utils-0.9.5-static-binaries.zip to where locally.
--> Extract each one to the same directory (again they won't overwrite as attached).
--> Go to the root of your sdcard on your INTERNAL PHONE storage. (hint: this is the same root/top-level folder you get with MTP when you go to browse Internal Storage from say a Windows PC.
4. You can do it, I belive in you. Just do some trial and error if everything (you can't hurt anything if you're still not exactly sure where to copy the EXTRACTED 2 zip files to (hint: 6 to copy in total).
5. Please tell me you're rooted so you have permissions to let stickmount pro do it's thing. If not I'm sure you can figure it out from the above w/ a little elbow grease.
:good: :highfive::victory:
6. If you read this far then you're trying so I attached a picture so you know I'm trying to help . The rest is up to you my friend and please let me know when you get it working. (last tip is try ES Explorer if after mounting in StickMount if you need a quick free browser).

I had already done this but I wasn't sure which root memory required the files. so I left the zip files in both external storage and internal storage extracted and without extracting the reason for asking was so I can clean up the double files from the places where it isn't needed. I appreciate your help. And yes I'm rooted running DU Rom since test builds lol
Also it doesn't matter where you put files on internal or external I tried both and it works. However I get a pop up which says it's not compatible and I should format but I ignore this message as it still works.

Cheers mate and glad you got it working! :highfive:
Paragon NTFS mounter app can also be used if you are rooted.
