Title: Android USB File-System
Post by: Herkules on December 26, 2013, 07:16:56 PM
Hey,
one simple question:
Wich file system does the Android OS support for the USB-Hosts?
Does it support only FAT23 or every FAT-system or every filsystem including NTFS?
And does Android support more than one partition for the USB devices?
Hope you got my point and understand my question ;) (sorry for my english)

Greetings

Hi,
I haven't tried with the android image for A20, but I used to have a tablet with Allwiner A10 SoC running android 4.1.2 (cyanogenmod). It was able to mount (automatically) two partitions from one USB flash driver connected to the USB OTG port. Both partitons were NTFS. I haven't tried with more than two partitions but I guess it will work.

From Wikipedia (http://en.wikipedia.org/wiki/List_of_features_in_Android):
"External storage
Most Android devices include microSD slot and can read microSD cards formatted with FAT32, Ext3 or Ext4 file system. To allow use of high-capacity storage media such as USB flash drives and USB HDDs, many Android tablets also include USB 'A' receptacle. Storage formatted with FAT32 is handled by Linux Kernel VFAT driver, while 3rd party solutions are required to handle other popular file systems such as NTFS, HFS Plus and exFAT"
