Failing Disk Utility

I wanted to create a new partition using boot camp for a windows boot. That failed so when I checked my drive in disk utility and tried to repair it I got the error listed below. I've tried recovery mode and single user mode without any luck. Any solution for this? Thanks

APFS is a pain, I've seen exactly one report that TechTool Pro 12 could repair an APFS volume that Disk Utility/fsck could not, the general drill is clone your working drive, erase the drive all new APFS, clone your data back...

Carbon Copy Cloner...

Disk Utility reported an I/O Error which usually indicates a failing hard drive. You may want to run DriveDX on the drive(s) and post the report(s) here using the "Additional Text" icon which looks like a piece of paper.

I've done a full wipe and fresh install. Here is the DriveDX report.

Thanks a lot to all of you.

I don't see anything wrong with the DriveDX report. It all looks good. The "Overall Health Rating" I believe is an incorrect interpretation of one of the attributes assuming the label is correctly listed as a temperature reading.

It seems you have a MBPro 15" (Late 2016) which has an integrated (aka built-in) SSD that is not removable.

If erasing the whole physical drive and either reinstalling macOS or restoring from a backup doesn't help, then you may want to take the laptop to an Apple Store to be checked out for free. In later versions of macOS you may need to click on "View" within Disk Utility and select "Show All Devices" before the physical drive appears in the left pane of Disk Utility.

Thanks for the reply.

I was already thinking of doing I've never used Carbon Copy Cloner. Was thinking of using time machine. Would you recommend using Carbon Copy over time machine? Im not really worried about losing files and what not but more about losing saved settings, preferences, passwords and stuff like that.

Right thanks I'll try it out looks pretty good. So if I understand correctly I back up my stuff using CCC or TM to an external drive. Then when its all done I have to boot into recovery mode and erase the drive and format to APFS then back out and chose reinstall macOS. Then after it installed boot into recovery mode again and restore from the backed up drive?

Sorry kinda new to this.

Yeo, I prefer CCC, though TM should work, CCC gives you an exact current copy & bootable volume, which is really handy for problems.

I use both here, but if I only had one choice it'd be CCC for certain.

Hey, no apologies needed, yes those are the steps if you desire TM, if using CCC...

After cloning, restart & hold alt to select CCC clone to boot from , from there you can Erase the Internal Drive, Clone Back, & CCC even offers to make a new Restore Partition, much simpler & you can use your Mac booted if the CCC Clone on the external while you're cloning back! :)
