Try shutting the computer down and disconnecting the IDE and power supply cable from the Sony.
Start the computer without the Sony connected.
Shut the computer down again and reconnect the IDE cable and power supply cable to the Sony.
Boot up again and see if the drive is now working and recognized.
Don’t ask me why, but this sometimes works. It is likely caused by certain combinations of motherboards, chipsets, and power configurations that can affect the drive when powering up. Removing all cables and reinstalling seems to reset the problem condition.
