Mount HDD with multiple partitions

Question

I have an external HDD with two partitions. Both are ext3 partitions and works fine with Linux. When I plug the USB HDD in my Android device, it does not work. I see some errors in dmesg:

I see the device at /dev/block/sda but I don't have any idea about mounting it manually. I was expecting /dev/block/sda1 and /dev/block/sda2.



How do I manage those partitions?

Answer

I can't fix the original issue.
I have just merged all the data in a single partition. I have no idea why the system can't mount the disk with two partitions.
