Access database recovery
Access databases can contain tables, relationships, forms, reports, macros, modules, and attachments in a single ACCDB or MDB file. Interrupted writes and shared-file problems can affect more than one object type.
Understand the symptom
Microsoft recommends a backup before Compact and Repair. A partially successful repair can place problem details in MSysCompactErrors, and a split database may have separate frontend and backend files. Recovery therefore requires knowing which file contains the tables, whether users were writing over a network share, and whether the disk itself is stable.
What you may see
The header, file version, or internal pages may be damaged or the file may be incomplete.
Access detects a prior interrupted write or structural inconsistency.
Tables, forms, queries, attachments, or rows may not be referenced correctly.
A stale lock, active user, permissions problem, or network interruption can block safe repair.
Protect the source
A successful open does not prove that every record and object survived.
Repairing while another process writes can produce a new inconsistent state.
Repairing forms and links does not recover tables stored in a separate backend file.
Do this now
Close Access and stop scheduled jobs, integrations, and shared users.
Copy ACCDB, MDB, LACCDB or LDB, frontend, backend, workgroup, backups, and linked data.
Note Access version, split-database layout, network path, errors, and the last known working time.
Image a failing disk or unstable share before repeated copies and repair passes.
NEPFOSYS process
NEPFOSYS identifies the database format, split layout, object inventory, and storage condition.
Repair, import, and object extraction paths are tested without changing the original.
Recovered tables, relationships, attachments, forms, and business-priority data are checked.
A clear next step
Start a case with the exact symptoms, incident timeline, prior attempts, encryption details, and the files that matter most. NEPFOSYS will route the case to the appropriate DFW intake or nationwide mail-in path.

No. Microsoft notes that partial repairs can leave a record of objects that could not be repaired. Validate the output against the original requirements.
Keep the ACCDB or MDB, lock files, frontend and backend, linked data, backups, workgroup files, and the original storage.
Yes. Shared-file databases depend on stable file locking and writes, so outages or dropped connections can leave inconsistent pages.
