I enjoy using ND2901 for quite some time and it works very well. However I still have problem with accessing it's content from tablet Dell Venue 8 7840 with Android 5.1.
Once I connect ND2901 Android reports external device empty or with unknown file system. Seems it doesn't work with exFAT.
That is because your pad does not support exFAT.
The file format of ND2901 is exFAT.
Google with 'Dell Venue 8 7840 exFAT', then you will find several users same problem using with exFAT formatted SD cards.
You need to contact Dell for that.

Thank you for the quick response, is there any way to use different FS on ND2901 and still have all it's functionality?

The file system of ND2901 is fixed to exFAT.
We changed from FAT to exFAT to support file size larger than 4GB.
