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?
