Data Transfers · Setting up a transfer
Can I transfer to a USB stick, SD card or other disk that isn't my main external drive?
Short answer: Yes. Pick a folder on any connected disk — USB stick, SD card or a second drive — with the folder button. Only your main Storage Studio drive gets “Waiting for drive”; connect other disks before the transfer runs.
Yes. The folder button lets you choose a folder on any disk your Mac can see — a USB stick, an SD card, a second external drive. Data Transfers treats it like any other local folder.
The Waiting for drive behaviour applies to your main Storage Studio external drive. For another disk, make sure it's connected before the transfer runs; if it isn't there, the transfer can't reach the folder and fails with an explanation, and you can run it again once the disk is back.
