[FireDAC][Phys][SQLite] ERROR: disk I/O error

Also, check if there is sufficient disk space for the file repository.

Block not found file: 2175, block_id: 1
The file is not found in the file repository index_db. This can occur if a new file repository is created for a new installation based off an import from another installation. The older files are associated with the original/source installation's index_db, and are not in the new index_db. One solution is to ensure that the orginal file repository (both the file structure AND the index_db) is used in the new installation.
