    Thanks Patrick. Actually this is old news as it was brought up in several Apple warnings about APFS. Still good as a reminder since converting a Time Machine drive to APFS very nicely destroys the LINKs that Time Machine uses to store file data.

    I might also add that if you're a user of CCC or SD for cloning, that you likewise should not convert those drives to APFS.

    Gheese Apple!! And thanks for this CCC WARNING Charles, and a recent notice from CCC sure confirms this that I hadn't read. And no wonder it's titled with: Another warning: just in case.

    Quite a switch from their earlier CCC pages saying they figured everything should work OK. Really NOT it seems!!

    Especially according to a recent article:
    macOS may lose data on APFS-formatted disk images

    All old news, Patrick. Apple warned about not using APFS on anything except internal SSDs when they released HS. Plus, just about every website carried that warning. The latest MacWorld article provides more information about why TM drives, in particular, must remain HFS+, which is nice, but Apple did say not to do that last year.

    Thanks for the reminder Patrick. I'm sure there are users out there that will need constant reminding of this.

    Maybe so "old news" for you and some others Jake, but I'm sure there are some who have missed the news or some of the "additional warnings" that seem to be cropping up.

    And I'm sure there are still many who still don't RTFM or even heed some apple warning!!! But gheese, even if they did, I guess apple didn't make a lot of things very clear as there are sure enough questions about their APFS on the web.

    And also a reason I added the "Just another WARNING and HeadsUp:" notice.

    Maybe some will see it and vaguely recall something about not doing something with the APFS they're not supposed to.

    And so your external drive is HFS+, and then you buy a new Mac. Then do you convert the external, or buy a new one?

    (Sorry, no time to scour the article to see if my answer is there.)

    I would recommend leaving the external as is. HS can read/write HFS+ just fine, there is no benefit to changing unless the external is an SSD, and even then the benefit would be much smaller because the throttle on externals is going to be the interface speed more than the drive format. But to *really* answer the question I would buy a new one, just because you can never have enough storage and if I can "blame" the new machine on the need for a new drive, that's great!
