Usb hdd not appear in music library

I have reformatted 300GB usb HDD with NTSF. There is no problem. I will do the same work for 2TB USB HDD.

You formatted as ntfs, conencted via usb and is seen by volumio?

Yes, I formatted 300GB usb hdd as NTFS. VOLUMIO has seen and read all songs. But I can not reformat 2TB USB HDD yet. I think I will able to format it the they after tomorrow after backup.
I wonder it will work or not.

I am happy that the NTFS worked. I think it is a more efficient HD formatting and might be easier to read that FAT32.
