I have an iMac (Retina 5K, 27-inch, late 2014). A while back the fusion drive died and I split them and used the SSD for the OS and an external 2TB SSD for storage.
The only issue I have had with the computer from this until now, is that it did not want to go to sleep. It also sounded like the HD kept spinning.
As of today the iMac keeps crashing and rebooting. When it's back up it warns that it can't read a connected drive.

I believe ST3000DM001 is the culprit. I can't dismount nor format it.

Is it reasonable to think the old HDD is making my iMac crash?
If so, would a working fix be to remove power and data cable from the HDD? (I hope that is possible without interfering with the internal SSD.)
Or is there a less intrusive way (without having to take the iMac apart), where I can disable the old HDD completely?
Any help or suggestions are very much appreciated.

I finally build up the courage to try and disconnect the faulty HD. I was sorta successful. The screen cracked a bit and my iMac is now assembled again with duct tape. But it seems to work. There was no error when starting the iMac, and it has been running now for 30 mins without issues. I will update this if that changes, but I'm having my hopes up.
