The correct procedure in this situation is : - check cabling in case vibration has dislodged the power or data connectors - replace the disk - restore from backup - optional : attempt to recover the disk using vendor-supplied disk recovery tools, or return to the supplier for warranty replacement Even the most expensive IDE disk is not worth more than a few hours of downtime and operator time, and it sounds as though yours has thrown in the towel good and proper. You should also check that the disks in your systems are not overheating; poor ventilation and subsequent overheating will drastically shorten the life of your disks. > Charlie Reese -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
