Check physical write protection

If using a CF card, inspect the physical write-protect switch on the card edge. Ensure it is in the unlocked position (not towards the contacts). Remove and reinsert the card if necessary.

Always shut down the control properly before removing CF cards to prevent filesystem corruption.

Verify file attributes

In Programming and Editing mode, navigate to the file, press EDIT key, select FILE, then Properties. Check if 'Read Only' attribute is enabled. Deselect this option and confirm with ENT key.

Check directory permissions

Navigate to the parent directory (TNC:\, SYS:\, or subdirectories) and verify directory attributes. Some system directories have restricted write access by design—save user programs to TNC:\ paths instead of SYS:\ paths.

Tool tables (.T files) and preset tables (.D files) must reside in TNC:\table\ directory with proper write permissions for edit operations to succeed.

Test network connectivity

Press MOD function key, navigate to Network Settings, select the configured connection, and use the Ping Test function to verify the file server responds. Check that response times are below 50ms.

High network latency (>100ms) can cause intermittent file access failures even if ping succeeds.

Verify network share credentials

In MOD → Network Settings → Network Shares, verify the username and password for the shared drive. Re-enter credentials if necessary and test by browsing the share from the File Manager.

Password changes on the domain controller require updating credentials on the TNC control or file access will fail.

Reconnect the network drive

In MOD → Network Settings → Network Shares, disconnect the affected share, wait 10 seconds, then reconnect. This reinitializes the SMB connection and clears stale sessions.

Review error log for disk errors

Press MOD function, select System Information → Error Log. Look for entries indicating 'disk read error', 'bad sector', or 'filesystem inconsistency' that precede the 130-009E alarm.

Frequent file access errors on the same drive indicate imminent storage failure—plan for replacement.

Backup critical data immediately

Use the File Manager to copy all NC programs, tool tables, preset tables, and PLC programs to a USB drive or network location. Do not delay this step if filesystem corruption is suspected.

Do not attempt write operations to a failing drive as this may accelerate data loss.

Perform filesystem check

Boot the control into Service Mode (hold MOD + CE during startup on most TNC models). Access the terminal and run 'fsck' on the affected partition (typically /dev/sda1 for internal drives). Follow prompts to repair errors.

Filesystem repair can result in data loss. Only proceed after backup is complete.

Replace storage medium if necessary

If filesystem errors persist after repair, the CF card or SSD has likely failed. Replace with a Heidenhain-approved storage medium and restore from backup using the TNC Restore function.
