External Disk not ejected properly
21.5" iMac running latest ios. Seagate external drive for backup. Seagate had an update recently that required ejecting the drive. I ejected the drive, it no longer showed on the desktop, and unplugged the drive. Restarted the iMac and plugged in the drive. Now I get messages about the External drive not properly ejected. Finer shows the drive and the proper contents. Any ideas why I would be getting these messages? Thanks.
iMac 21.5″, macOS 12.3
