I'm having some trouble formatting my WD my passport in High Sierra.
I did not purchase the Mac version of WD external hard drive, and was wondering if it can be formatted to JHSF+ or to the new APFS film system. I don't want to use exFAT or FAT32. Currently it seems to be formatted to exFAT.
But the problem is this.. I am unable to format or rename this disk. Not even to exFAT or FAT32..
anyone help?.... please.....

Try this:
Open Disk Utility (not in Recovery Mode) and change the View drop-down (upper left corner) to Show All Devices. Then select your actual device - not the indented volume - and then the Erase making sure the Partition Map Scheme is GUID and format is Mac OS Extended (Journaled). This should recreate your single volume as GUID/HFS+.
Great answer. Thank you so much.

Did you ever resolve? I have same issue.
I have the same problem with WD my passport ultra 1TB external USB disk (after upgrading to High Sierra) but fortunately I've installed Windows 10 on BOOTCAMP and then Parallels Desktop 13 on macOS 10.13.5 and do active as a system Windows 10 in this Parallels, and then surprise, after booting Windows 10 from Parallels Desktop 13 connect WD disk it is visible, accessible as read only , but I can copy everything from disk to any place I want, writing to disk is still not possible. I think the problem is on APPLE APFS and file permission, security, too much and the result is not mounted disk and unreachable disk. Regards. JACEK from Poland. BTW in Apple store they try to connect disk to an older system and it was not visible, they say it is broken - maybe, I look forward to solving this problem by Apple.
Please, distribute this message everywhere you can, because Apple is not worried about it yet, and he knows that if you want to upgrade your original 128GB SSD drive in MacBookAir, you should have High Sierra 10.13.5 otherwise the new one SSD 1TB drive is invisible because of new EFI.
Yes it is resolved. Did you read the thread? You format at the device level not at the volume level.
