Hi,
I have a problem, I'm no longer able to format my external disc into any other format than APFS after try it to see how fast is it. I need to format it back to Mac OS extended in order to keep using it with my router to manage the back-ups.
Please, tell me what to do. Changing to PC is an option because Apple is screwing it up a big time!
Thanks.
MacBook Pro with Retina display, macOS High Sierra (10.13.1), 10.13.2 beta
I resolved it! I ran this on Terminal: diskutil apfs deleteContainer /dev/diskID.
Thanks Ironkrozz. This solved my issue as well.
For others. Please do not format your Time machine drive to APFS. In case you do that use the instructions here to format it back to HFS+ and then set it up again.
At the time to erase the disk, the format selector just let me select APFS format options.
Before this, I had all the possible options to format, all APFS formats shown in the picture, Mac OS Extended, Mac OS Extended (Journaled), Mac OS Extended (Case-sensitive), Mac OS Extended (Case-sensitive, Journaled), MS-DOS (FAT) and ExFAT. Now after format with APFS they're no longer available, as is shown.
I also tried to format through Terminal but it says "You cannot manually format an existing APFS Container disk".
And also as a volume and the message was the same.
If you need any other information, please tell me. Thank you.

Describe exactly what happens when you attempt to do that.
Can't format on Mac OS Extended anymore
