I attempted to restore my macBook air (13" mid-2012) using time machine, and time machine restore failed (over various backups that I tried) repeatedly. I was eventually able to reinstall the OS from macOS recovery, and my computer is responding well now, running Mojave 10.14.6.
The backup drive (SeaGate Backup Plus) that has my time machine backups and other data that was recognized in the recovery menu now fails to be recognized. It doesn't show in Disk Utility or NTFS for Mac. The drive is spinning. Any suggestions?
