Hi all, I have a 4TB WD MyPassport Ultra and it does not mount on MacBook Pro now. It was working fine this afternoon but not now. I ran a disk utility first aid on this and it was reported “Problems were found with the partition map which might prevent booting”.

Could anyone help me to solve the problem? Thanks!
