After reformatting my hard drive from APFS to HFS successfully .
(due to it running far slower as APFS )

I am unable to defragment the hard drive using Tech Tool 13 ( OS Mojave )
as TechTool is saying cannot defragment as drive is APFS ?

any ideas?

Thanks
 
Perhaps you really didn't reformat the drive as HFS+. Check that. If you did, and TTP says otherwise, perhaps you're not using the latest version of TTP or TTP has a bug. Either way, trying to defragment a hard drive has long been a past practice and isn't done any more on HFS+ volumes because HFS+ defragments automatically behind the scenes. And if you just reformatted, it's not fragmented to begin with. So I would not worry about it and just move on.
 
Have you read the manual

Thanks for the replies.

I am running another Mac on 10.9.5 which i defragment regularly due to doing a lot of Video and Audio editing and i do find it runs a lot faster after Defragmentation?

I am running TechTool from an external so not from the Drive i am trying to work on

Possibly wrong version of TechTool i am using 13 maybe 14 would work?
 
I have TTP13 running in Mojave, but never defrag drives.
It's not required.
If your having trouble with v13, I doubt v14 will fix it.
Have you checked in disk utility that all partitions are hfs+.
 
Thanks MarkC426

I will double check in Disk Utility that I have successfully reformatted the Drive
 
Chabig.
You were right
I checked and is still APFS ?!

Very strange as I def picked the +HFS Mac OS Extended (Journaled)
option after I wiped the drive ?

I didn‘t know that? it explains a lot
I didn‘t realise an operating system could change disk format
Back to High Sierra I go !
Thanks :)
 
If it is SATA not SSD will High Seirra keep it as +HFS?

If not how do i force it to HFS +?

Thanks
 
I‘m running my other older Mac on 10.9.5
because its faster more stable and works better for me than newer versions of OS X

Its the new version of Disk Utility introduced with High Seirra that is causing me the problem

It all makes sense now :)

Thanks for your help

I cloned my NVME (Mojave/APFS) to another SSD. although it cloned Mojave over but remained HFS.'
I thought Mojave would not install if not APFS?.
Seems fine on a HFS format.?
Should convert the drive to APFS ?

Mojave installs and runs perfectly fine on HFS, just it will not, or can't receive any updates, this includes any and all updates.
 
Thanks jbarley, greatly appreciate it. I went ahead and converted the volume.

jbarly (RUSH), great band !

Running Mojave in a HFS+ drive for a couple of years and works fine. No problems encountered. As pointed out by other members, the security update is disabled with HFS+. Mojave also ran well in a mechanical HD as HFS+
 
Macsonic --

Even though you can't INSTALL Mojave to HFS+, you CAN "clone" a Mojave install from APFS to HFS+ (using CarbonCopyCloner).

However, I found that Software Update will not work properly (can't find updates) when running Mojave on HFS+. I've heard there's a fix for this, but haven't pursued it.
