The reason it is not compatible is because it uses NTFS format. You can get Android to work with NTFS, but it requires rooting.
The other way around this is to reformat the drive to exFAT. Just format it like any other hard drive. Shouldn't be too complicated. Just back up your data before doing a reformat on the drive.
I have an external 1TB drive that I reformatted from NTFS to exFAT to make it compatible between the Notes, desktop and notebook. Also, exFAT does away with the limitations associated with FAT32. So much better at handling larger file sizes.
