Hi,
Firstly, I have trawled Google and many problems people have with ICS and apps being restricted to writing to the internal SD card, or even seeing/mounting SD cards and external drives.
This is not my problem, but I think it's related to the decision by Google to restrict app access to internal (phone) SD cards.
I have an Onda Vi140 10"tablet, but I'm not sure it's restricted to just this, so I've posted here. Please move if this is wrong.
I can, with all file managers:
1) See and read any files on any TF card I put in the external Slot.
2) See and read any files on any USB stick I put in the external Slot.
3) Read & write to them via the clunky stock File Manager.
3) Ditto both on my WIn7 x64 PC and move/edit files.
I cannot get Astro or ES file explorer to read/write - even after rebooting with the flash drive connected.
/mnt/sdcard - internal 16GB (System and apps)
/mnt/extsd - external 16GB TF (Storage of docs/music/photos etc.)
/mnt/usbhost1 - external USB thumb drive (Or Fat32 Hdd)
I don't mind ICS restricting to the internal 16GB /mnt/sdcard as I only install apps there, and am happy to save within apps to this location.
However, I often want to transfer a document from the tablet to my thumb drive, and vice-versa, like with my laptop. this is an essential operation for a portable device, and I'm both surprised and frustrated it's not readily working.
Given that the internal File Manager can do it, what's the problem?
My device is rooted. Could I install an app to open a terminal and set global r/w permissions for /mnt/extsd /mnt/usbhost1 - The system doesn't use them for apps. They are both just storage volumes. The whole system and all apps are in the /mnt/sdcard and that's unlikely to change.
Any assistance would be appreciated.
Regards,
David.
Solved on this very forum here! (Not sure why it didn't turn up in my search results.)
I can now read/write on my external TF and plugged in USB stick.

Hey guys so u was transferring my files to hard disk from my phone through otg...I am using WD passport 1tb...default file manager doesn't support it but es explorer works fine ...thy PROBLEM is that I am able to transfer files from my internal storage to hard disk but not from my inserted memory card to hard disk ...it shows operation failed and all my permission are on
If that disk is for usb3.0+ that maybe the problem i have issues with usb3.0 before. Also some non stock options can interfere with file tranfers.
Yeah the problem was actually the NTFS format which was solved by exfat/NTFS driver
Thanks for replying buddy
Hi.
my tablet is samsung android 5.1.1 and rooted.
this is about one month that this problem started.
When i transfer any file from computer to external sd card by USB cable it can not opend and after restart i see this file is not in my sd card! (move, music,pdf,...).
but if at first i tarnsfer any file from computer to internal memory by USB cable and then i copy/move by android file explorer from internal memory to external sd card, the file can be opend and editable!!!
I think a hacker or an app has changed any system files therefore this problem occur. or maybe some other rezone.
Please help for solving this problem.
Thanks.
Hi. Is there any way to apply external storage permission without the dialog for it?
What I mean is, if I start a file explorer for example and want to copy a file to or from the external SD card, there comes a window which lets me grant access to the external SD card. Mostly it says that you need to select the SD card and then grant access.
And I don't mean the storage permission, which I can allow in the app info tab.
Is there a way to do this manually if an app requires this permission, but doesn't shows up this permission window?
Thanks in advance

hello, since android 6.0 an App need to request a permission through user click the permission dialog. so there isn't a way to manually, except system signature app, they can share a uid with system process which not need to ask a external sd card permission. hope to help you!
I have that TV box and the only app that can write to external storage is the internal File Manager.
There are 2 system apps: internal storage and multimedia storafe that have their permission dissable and I can't change them. I suspect this is the issue.
Anyone can help? Perhaps with an adb command? I don't want to root.
