Apple Service in Austin has contacted me regarding my SR MBP. It seems that some units with the 160GB 7200rpm drive experience drive access problems, and that MBP owners with drives with particular serial numbers are being contacted. They promise to repair/replace the drive free of charge, if needed. They sent me a box so that I can ship the unit to them. I contacted Apple in Cupertino and they have no knowledge of this recall, but Apple Service in Austin confirms it.
