Time machine not working anymore / crashes everytime during preparation

Hi there,


On my aunt's iMac 2017 with macOS Catalina (10.15.4) time machine is not working anymore since March.

It crashes everytime when it starts to prepare for a backup. We tried to restart the mac, plug off and plug on the external hard disk but that did not help.


I checked the crash reports but I can't understand them. I attached the recent one and I'm looking forward to your help.


Thanks

Thomas

The drive may be failed or failing. Please run First Aid on it several times, you will find FA in the Disk Utility App. If any errors apper that simply confirms my hunch, however if no errors occur that does not mean it is still not failing.


What is the brand of the EHD being used for Time Machine?
