I am trying to use my external USB3 Toshiba 1TB disk, to plan a backup of my as-604T.
unfortunately, each time I connect my disk to usb3 port (1xusb 2.0 already used by a different external hd), I receive the above mentioned error, (Unknown error.: API Error) and the managing of the error is not the best practice....

I try to format it both NTFS and FAT23. the problem is always present.

Of course, the usb3 disk is correct working on my pc.
Any idea ?


thanks
Marco
