HD WDBBGB0080HBK-EESN 8TB My-Book is sudently read-only

My WD HD WDBBGB0080HBK-EESN 8TB My-Book was farmated with exFAT.
After working few monthts OK, sudently changed read-only.
I can’t change this to regular read/write modus.
Using DISKPART with fokus on this HD with “attributes disk clear readonly” does not help.
It still shows:
“* Datenträger 3 Online 7452 GB 0 B *”
(Free storage is steel 0 Bytes)

Using “DISKPART> detail disk” shows:

How may I solve this issue?
Thanks
