Moving folders · Drive disconnects and interrupted moves
Why does it say "A drive transfer is in progress. This move was held"?
Short answer: Storage Studio is already copying your drive to another drive, and moving folders at the same time could change what's being copied. The move is held and nothing changed; start it again once the drive transfer finishes.
Because Storage Studio is already copying your drive's contents to another drive (a Transfer Drive or Backup Drive job), and starting a folder move at the same time could change what's being copied mid-way. The move is held rather than run alongside it.
Wait for the drive transfer to finish — you can follow it in Storage Studio — then start the move again. Nothing was changed by the held move.
