Hi Dave,

Perhaps I was not clear, but I have an external drive partitioned in two parts.

One as SD clone partition and the other for Time Machine.

I upgraded to 10.13 so my internal SSD drive is now APFS. The external drive is still Mac OS Extended (Journaled).

If I open Disk Utility I can only convert the Time Machine partition to APFS and NOT the SD clone partition.

I that because the SD clone partition has 10.12 installed (which does not require APFS). So the only solution is to erase the SD clone partition and then used SD... For Time Machine it seems not of any importance if the partition is APFS ?
