Troubleshooting & messages · Moves and copies that didn't finish
Why did copying a folder take too long and time out?
Short answer: The copy stalled long enough to be stopped — often a sleeping, slow or failing drive. Your original is safe and Storage Studio retries later; check the drive's connection.
The copy stalled for so long that it was stopped — usually a drive that has gone to sleep, a very slow or failing drive, or a network location that stopped answering. Your original is safe, and Storage Studio will try again later.
### What to do - Make sure the drive is awake and connected directly. - Avoid moving to network shares or slow USB sticks. - If one drive times out repeatedly, test it in Disk Utility.
