M2 External SSD Disconnection - Why ?

[Washac]

Being a recent Mac Mini M2 owner I am getting a little frustrated with external drive disconnections.

In the Energy Saver option I set the Put hard disks to sleep when possible to OFF.

I have Amphetamine Drive Alive set to ON session set to Indefinitely and have wake drive every 60 seconds
yet still I get external drive disconnects.

Disconnects happening when?

Disconnects happening when?

I didn't put when because they just happen at any time, since posting it seems I have solved the problem ( Fingers Crossed ) I tried the drives in a different encloser and so far no disconnects. so I am putting it down the enclosere.

Which version of macOS? Besides: you tried a different cable? There is an older thread here on MR where some fixes/workaround to this are given.

One option is to mount the external drive(s)/device(s) and then kill the usb demon (which is responsible for connect/disconnect/reconnect) from the terminal.

The command is sudo killall -STOP -c usbd, which pauses the process until you either reboot your Mac or enter the command sudo killall -CONT -c usbd to restart the process. This often fixes the problem.
