If this is also a Matsushita drive, chances are it may also be affected.
To be sure you should dismount the drive and inspect it closely.
If you don't see damage on the solder side of the PCB, you should also
remove the front bezel.
You then should be able to see some of the capacitors.
If they are black, chances are they are the 'bad ones'.
