My Book Duo makes my iMac to crash

Hi, my My Book Duo 8 TB used to be my iMac’s Time Machine. After buying a new disk, I deleted all the datas from my My Book Duo. Since the drive is empty, it makes my iMac to freeze and crash.
When the disk is plugged, the Mac freezes, and restarts after a few seconds.
I tried to formate the disk through Apple Disk Utility > still freezing and crashing.
I tried to formate through WD Drive Utilities > still freezing and crashing.
I tried to follow those instructions [ https://support-en.wd.com/app/answers/detail/a_id/6266/kw/crash/related/1] > still freezing and crashing.
Any idea?

My 2017 MacBook Pro is crashing overnight on a regular basis since adding the WD Duo 12GB. I’m running the two drives without RAID. I formatted them as JBOD using Disk Utility. At first I formatted using WD Utility, but that caused even more crashing.

What macOS version are you having this problem? I recommend installing WD Drive Utilities on a PC, then reformatting both drives with the RAID functionality. WD Drive Utilities on Mac has always had a lot of problems and they still haven’t updated the application for Catalina. You won’t get support from WD on this forums or via email.
