[Q] Can´t write on USB storage - Nexus 7 Q&A, Help & Troubleshooting

I have the following ROM : [ROM][March 7][4.2.2] SmoothROM v5.0-Smoothest ROM-Deodex-Zipalign-Tablet UI-Stable
Now i have an 32GB usb stick (scandisk cruzer blade) on an otg cable (this works fine) on my N7. The stick ist ntfs formated.
In settings i can see it and also the right size.
But when i want to copy on it, it doesn´t work. Also i can´t create a new directory. Any ideas? Later i will try another stick

Do you see your stick in a file explorer?

AW: [Q] Can´t write on USB storage
Yes, i can see it. In the root directory there are the directories emulated and sdcard0. Also there is a directory usbdevice and nothing in there. But there are files on it

AW: [Q] Can´t write on USB storage
Ok. The stick seems to be the Problem. Another one, 4gb, is no problem. Write and read. Another file explorer says, there are no writing rights for the bigger stick? How can i change this. And what is the favourite file system on my Device?

External hard drive

How do I connect one and view it the tablet?

You must use a FAT32 formatted drive.
If there are pictures, music and videos on there, the appropriate applications will find them.
To browse, use a file manager. I personally like Dual File Manager.
Thanks but where would I go to locate the USB

If you use Dual File Manager it will see /mnt/sdcard as your default directory. Hit the Android Back Button once and down at the bottom you should see "usb_storage"

[Q] Transfering data between phone and A500 using USB?

I was interested in transfering files from my hone (Nexus s 4g) and my A500. I wanted to know if this is possible by simply plugging the phone into the tablet's usb port. If not, is there any drivers or apps i can download to let me do so? Basically, i want it to be like when i plug it into my computer. I want it to show up like a hard drive.
Also, i have a external harddrive and had a question on how to format it. When i right click hit format is comes up as NTFS being the default file system. The onl y other option is exFat. Is that the same as Fat32? I've heard Fat32 is the only file system that works.
Thanks for the help!

[Solved] Reformat KF sdcard?

Is it possible to reformat the usb storage/sdcard on the KF and what would be the best way to do it? Reason I ask is yesterday I repartitioned my KF using GNU parted so I can get more media/internal storage. After saving my handy work, I got the "msftres" flag and now when I plug the KF onto my Pc, it shows up empty like there are no files saved onto it, but when I navigate with root explorer, the sdcard/internal storage is populated. It doesn't even give me the prompt to mount usb storage when I plug in the usb cord. Thx in advance for the help.
Update: the issue was with automount, plugged into different usb port and reinstalled drivers and now it works. Thx for the help

Yes it is. If you are on windows mount the usb drive then go my computer and right click over the KF hdd and choose format.
I recommend Fat32
Hope this helps

Will this have adverse effects other than just wiping the info that's on the internal storage and then making the internal storgae reading as fat32?

You can also just delete any folder or file that you don't want on there if you mount the storage.

USB drive is empty

Hi.
Rooted Nexus 7 with Stickmount and a 32gb USB drive.
Drive is mounted and recognized
sdcard/usbstorage/sdh1 folder is present in file structure
copied an mp4 file to that folder
es file and astro file mgrs dont see the file and call the folder empty
ideas?
thanks.
Unmount your card then Reboot ur N7 and mount back its should work

With stick mount version 2 and android 4.2 you need to open the app that you want to use before you attach your USB stick! Read some of the stickmount threads!

If I want to use different apps with attached otg storage, I open the first app, mount storage, use app, unmount storage, close app, open other app, mount storage, then I can see it in the 2nd app.

The file structure in 4.2 is emulated, fused, and symlinked, so many of the directory paths aren't consistently visible in different file explorers.
The one that always works for me is /storage/shell/emulated/0/usbstorage/sdn1
Try it, and let me know if it solves your problem.
You guys are awesome. I kept the otg cable out of the port, loaded my video app, put in the cable and viola, my files came up and played fine.
THANKS!

[Q] USB Port?

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.

I have rooted my nexus, installed and mounted the sd card through stickmount and am still not able to write to it. I can't see the files on it either (if i install nexus media importer, i'm able to 'read' the card, but again can't write.
Any suggestions?

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.

Thanks for the response - i mount it through StickMount and am not sure if it will be visible if i don't use any program.
How do i edit the vold.fstab ?

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.

It doesn't exist unless you put it there, look at my "4.2.1 boot mod + otg"thread for details.
