Poma,

You post all these seemingly great things to install, but not why to 
install them.

Is this a better driver for USB devices?  Does it give better reporting 
to know what the condition of the drive is?

Is the drive even failing or is the current driver reporting too much 
already?  That these are really fairly normal errors that are handled by 
the drive.
