IMAPI_E_IMPORT_READ_FAILURE

IMAPI_E_IMPORT_READ_FAILURE reports a media read failure while IMAPI imports the previous session. The return-value text identifies a block read on the source disc; this occurs after the import path has selected a filesystem and started traversing recorded structures.

Treat the source medium and recorder as the primary evidence

  • Record the physical recorder, media identity and filesystem selected for import.
  • Preserve the block information reported in the formatted error text or surrounding IMAPI diagnostics.
  • Check for device/media errors before rebuilding the destination image hierarchy or changing filesystem options.

This differs from IMAPI_E_FILE_SYSTEM_READ_CONSISTENCY_ERROR: the latter says readable structures are inconsistent, while this code says a required block could not be read. A file-level copy tool may expose additional bad-sector behavior, but it does not guarantee that IMAPI can reconstruct a valid multisession filesystem from a partially unreadable prior session.
