In Mac OsHighSierra the Complete disk test in Wd utilities on My passport ultra does not work. At 10 % the test is broken.
Hi disk1,
Have you tried to perform the first aid test on the drive using Disk Utility?
Refer to the link given below for instructions.
Hi Alex,
Yes, I did that and in the meantime I also had contact with the support of Western Digital.
Sincerly
