Need to disable the external SD card on tablet android 4.2

[Jasmin74]

I Need to disable the external SD card on tablet android 4.2, how?

I don't want anyone who inserts any SD card to be able to copy files from my tablet to this external SD card ( I have 3 software pre-installed on the tablet thru which they can copy files) is there a way not to let SDCard1 be shown??

Any way to do this?? Thank you in advance

Without rooting and modifying the system software, I doubt it. Disabling the pre-installed apps you mention might slow someone down (they'd not be visible in the app drawer, so unless they went into settings they'd not know they were installed).

The best solution is not to give people you don't trust access, but I guess there's a reason that doesn't work for you. Would encryption help?

Well, no, I want this SD card slot as if it doesn't exist, no read nor write (permission) included !

Superglue.... or some other non conductive way of preventing the card being inserted would be a drastic option... but you could do it without rooting the device (although it would definitely void your warranty)

Any other bright ideas?

Your options are limited.

1. Root the device and modify the system software (probably at kernel level) to prevent SD access.

2. Physically prevent a memory card being inserted.

3. Open the device and disable/remove the card slot.

How good is your coding? If you can get hold of the kernel source code for your particular model & software release and identify the bit responsible for managing the SD slot you could remove them, build a new kernel and install it. You won't find a pre-built custom kernel like this because you have a very unique requirement here.

I'm not sure whether you could just misdirect the path to your SD card to a non-existant location with a startup script (init.d), if your ROM supports init scripts. I suspect this wouldn't be possible unless you have already inserted a card, but have never tested.

How have you managed for the last 2 years? If this isn't the same tablet, then buying one without an SD slot would have been a simpler answer (though would you then want to disable USB OTG support?).

Thank you Hadron, not so much for mobile coding..tablets were bought & i did disable it from a while but forgot how..
No pb for OTG & camera..but still the sd card, if you a know a good programmer I am willing to pay for the code.
