I get error codes when trying to reformat to APFS. This happens whether I try to partition, erase or convert the disk. Two examples below.
****when trying to do by Partitioning I get:
"An internal error has occurred. : (-69626)"
****When trying to do by Convert to APFS I get:
"A problem occurred during conversion from HFS to APFS
APFS Converter exit code is 1
Aborted conversion in commit mode so will restore type
Setting type of disk5s2 to HFS
Changing the physical disk partition type in shared mode
Partition modification attempt count was 1
Not mounting APFS Volume
Exiting conversion operations with error code -69860"
The disk appears to be normal and work normally in HFS according to DU and other testing.
I would like to use the disk for Catalina BU and need it to be in APFS format. Ideas?
Note the disk enclosure is USB 2.0 and Firewire interfaced – wondering if the controller in the enclosure might be the issue?
