Any current or former IBM CEs reading this? I'm not a CE, but I do have access to some old 9370 service manuals, though for the 9341/9343/9345 (SY27-7500, SY27-7501), not for the 9335. The one for the 9343/9345 says: 1. Power on the service panel 2. F1=Service Options 3. F4=Utilities 4. F5=Non-Customer tracks reformat But your friend should first run the Verification Test Procedures utility before reformatting the track in order to get needed REFCODEs. These books and the utilities all need that information in order to know what to do. If the verification utility doesn't complete successfully, then there are FRUs that have to be replaced.
