I'm using a Mac Book Pro mid 2012 running 10.15.7on Samsung EVO 1TB internally.
It was not possible to boot the computer last Friday. I tried to boot in recovery mode, the SSD was not identified as a bootable device.
I removed the SSD and tried to boot it using a UGreen IDE Docking Station without sucess.
Now I have connected the UGreen Docking Station to another Mac computer, fsck_apfs -fy gives the result that there are many invalid checksums, therefore the space manager is invalid,
the whole issue is here:
fsck_apfs
Disk utility gives the same output.
I run others tools like Drat/APFS Inspect, the output is the following:
Drat - APFS Inspect
As you can see there are a lot of checksum validation errors. APFS Inspect says an Ephemeral object is malformed.
Is there any way to fix this checksum error and get the SSD bootable again? Or is the only possible solution to format the entire SSD and reinstall the operating system?
I don't have any idea about the origin of this error and I couldn't find any information about it.
It would be nice to receive some help.
