What does it mean if a move fails with a read error while checking the copy?

\n

Short answer: The drive couldn't read back part of the new copy, so Storage Studio couldn't confirm it and kept your original in place. Reconnect the drive and retry; if it repeats, run First Aid in Disk Utility — the drive may be failing.

\n

It means the drive was connected but couldn't read back part of the copy Storage Studio had just written, so the check couldn't confirm it. Storage Studio keeps your original exactly where it was.

\n

An occasional read error can come from a loose connection; repeated ones can mean the drive is starting to fail. What to do:

\n
  1. Reconnect the drive directly to your Mac and try again.
  2. Run First Aid on the drive in Disk Utility.
  3. If errors continue, stop moving things to that drive and copy what's on it somewhere safe.
