For my daily backups i've switched from a relatively small USB stick to a 1 terabyte Toshiba USB powered device.
(My backups are not huge but i really like having a big device for the backups and anything else i want to put on it).
When i try to "export to (this) USB Flash Drive" the NEXT button is grayed out.
I'm guessing that Opus doesn't like this as a flash drive ?
