External Drives in Monterey

I'm seeing rumblings that I'm not the only one here...mid-2015 MBP and upgraded to Monterey and immediately after upgrade my external USB drive (Time Machine) and SD card (in the lost) periodically unmount themselves, give a warning and then randomly remount. This makes these external storages unusable- Time Machine won't even engage in the updated, current state.

MacBook Pro 15″, macOS 12.0

I’ve just had a success with a very simple fix. My external drive got to the point that it was disconnecting every few seconds. 


The problem: It was dirt in the connectors. 


Solution:

  • I disconnected the cable at both ends.
  • Blew out with a sharp burst of breath the female connectors in the body of my MBP and the port in the external disc, and
  • Blew out the insides of the USB-C male connectors.
  • Reconnected everything.


That was two days ago, and the external disc has not disconnected since then.
