Diagnostics in system profiler states that Power on Self-Test has failed.  Failure type: External cache.  Any idea how I can fix this?

Problem started while I was working in iMovie 6.  I went to delete two large video clips that should have freed up over 10 GB of disc space.  When I emptied the trash I did not get the space back.  Have run the Onyx utility to clear all of the caches but to no avail.  Onyx states that start up disc needs repair but I need a copy of OS X 10.5.8 to do this (Can't find my copy anywhere).  Used disc utility to repair permissions. I'm still getting the fail message in diagnostics that states that the Power on Self test fails, failure type - external cache.  Everything else on the machine is working fine with the excpetion of the phantom space I can't seem to retrieve.  Any suggestions?

 

Many Thanks:
