Ok so this phrase keeps coming up allllll the time. Only after I put the computer to sleep. It has now happened 10 time in the past 3 days. Usually when the compute is unplugged. Im on a MacBook Pro 2.4 2Gb 160hd. SR. bought in Late july. Could this be a hard drive problem? Or what is the reason for this. Im not running leopard. just tiger. should i go to the apple store? Thanks for any input about what might be going on.
