Erasing doc-id Record in APFS Disk (macOS Monterey) - Error 69845
When you encounter error 69845 while trying to erase a doc-id record on an APFS formatted SSD with macOS 12.7 Monterey, this guide will help you understand the issue and provide potential solutions.
Understanding the Error
Error 69845 typically occurs when there is a conflict with the existing doc-id tree during the erase operation. The doc-id tree is a component of the APFS file system that manages unique identifiers for files and directories. In some cases, this error can be caused by a corrupted APFS file system or external factors such as interrupted processes or power outages.
Preparing to Resolve the Error
Before attempting any troubleshooting steps, ensure you have a complete backup of your data to prevent any loss. Also, make sure you have the necessary administrator permissions to perform these operations.
Potential Solutions
Here are some potential solutions you can try to resolve error 69845:

Repair the APFS file system: You can use Disk Utility's 'First Aid' feature to scan and repair any issues found in the APFS file system. This can help resolve conflicts and allow you to erase the doc-id record.

Erase and reformat the disk: If repairing the APFS file system doesn't work, consider erasing and reformatting the entire disk. This will rebuild the file system and may solve the conflict causing error 69845.
