I have a problem with a family member’s Western Digital My Passport drives. He has a 27” 2017 iMac. He has two new WD USB 3 drives. They are regularly swapped and used for Time Machine backups, but they are unreliable. He gets a message titled “Time Machine couldn’t complete the backup to...”, “Unable to complete backup. An error occurred while creating the backup folder”. If he ejects the drive, unplugs it and the plugs it back in it will backup just fine. He says he can put the iMac to sleep, then wake it up and manually force a backup. If he does this it backs up. But other times he can wake the machine and find this error. Does anyone have any ideas? I don’t think this is related but I also couldn’t reformat these drives to HFS+ when I got them using Apple’s Disk Utilty. I couldn’t rename the drive either. I had to use the Western Digital utility to reformat the drive. After that I could rename the drive. Is Western Digital to blame for this nonsense or Apple? I’ve used WD drives in the past and loved them, but this is unacceptable.
