Hi
This might be a problem with your hard disk- there is a process for installing and re-initializing the hard disk for the TNC426 available in their service manual (available on the heidenhain website)
You would need a new 2.5gb IDE Hard disk (SSD works better in my opinion) and after reinstalling the TNC system you can reload your parameter and PLC backups
Best regards
