I desperately need your help on this problem.
As you can see in the screenshot above. The My Cloud app only regonize my EFI partition thus I cannot access the main partion. Through this artice (http://support.wdc.com/KnowledgeBase/answer.aspx?ID=11766) I’ve learned that it can only access the 1st partition and i"m supposed to formart my drive to one partition only (http://support.wdc.com/KnowledgeBase/answer.aspx?ID=3865), but there’s no action can be made on the EFI partition. So what am I supposed to to to solve this problem. I deserately need to solve this because I only have the drive to backup my gopro(es) sd cards while travelling. Please help.
