MacBook Pro EFI Firmware Update 1.7 for Mac OS X 10.5.7
MacBook Pro EFI Firmware Update 1.7 addresses an issue reported by a small number of customers using drives based on the SATA 3Gbps specification with the June 2009 MacBook Pro. While this update allows drives to use transfer rates greater than 1.5Gbps, Apple has not qualified or offered these drives for Mac notebooks and their use is unsupported.
To complete the firmware update process, please follow the instructions in the updater application (/Applications/Utilities/MacBook Pro EFI Firmware Update.app). The updater will launch automatically when the installer closes.

It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed a wrong driver. Problems can arise when your hardware device is too old or not supported any longer.
