transferring of photos to external drive

After I tried transferring my photo library to an external drive, it says "The library cannot be opened" whenever I open it. Can someone help me?

MacBook Air 13″, macOS 11.1

Hi

Is the external drive correctly set up for using with a photos library?


It must be formatted APFS or MacOS extended (journaled) (preferred for spinning drives), and not be (or have been) used for time machine. It must have the 'ignore ownership" checkbox ticked. It should not be on a memory stick, SD or similar. It stands to reason that if you want any sort of reasonable performance it should be a fast drive with a fast connection.


It must also not be a network drive (a direct connection is required - eg USB or Thunderbolt)
