    Default format micro SD card to ext3 or ext4 to use it in android tab.

    Hi I am Rupesh from India and I have lenovo a3000h tab and 64 GB external SD card and I want to use it in lenovo tab.

    Few months back I was discussing with some people in hydrogen audio ( a forum which discusses about audio technologies) and one person raised question that every android device manufactured up to now supports external SD card of size 2 tb provided there is a slot for it. I have argued that it's impossible because manufacturer places restrictions such as "the phone xyz manufactured by me only supports upto 64 GB" etc.,. He has never accepted me.

    He said that if the memory card is formatted with fat file system then any android device can read and write files to it because android has the ability to access external SD card of size upto 2tb. He also argued that it is related to android os and not with hardware. Is it true.

    At present I have android tab called lenovo a3000h and its manual stated that it supports external SD card of size 32 GB. I also have external SD card Samsung evo of size 64 GB and it is of type sdxc with uhs1 file transfer. Is there any possibility of using it.

    Can anyone of you suggest if it is possible to format SD card I mean to which file system ie., ext3 or ext4 or fat I have to format in order to access it in the tab specified above.
    Regards,
    Rupesh.

    The a3000h can only use SD cards 32-G or less, cannot use your 64-G card.

    Yes, there are size limits with older devices like that. The person at Hydrogen Forum is wrong.

    I have inserted one of my friends 128 GB sandisk sdxc micro SD card in lenovo a3000h tab and I am able to access all the contents present in that memory card. It is formatted as fat.

    Okay, good to know.

    I think that at some point it must have had an update to the firmware, then, though could not say for certain. I am still quite sure that, originally, that model could not access a larger SD card like that.

    If it works with fat, then it should work with a Linux filesystem.
