Hi everybody, I have a 7200.11 ST3500320AS (firm SD15) with BSY error At first I tryed to replace the PCB by an other ST3500320AS --> not recognized by BIOS... Then I tryed the gradius solution: /2 Z (Spin Down Complete Elapsed Time 0.147 msecs) With the POWER CONNECTED to the PCB board I mount the board back on the HDA case U I hear the motor and 7 min after I have the same message: (I use a power sullply +12V-4A +5V-5A) why it doesn't work? Thanks
