Hey guys, my iMac has been running strong for about 9 months now. The only gripe i have had is that is has begun to get SLOW booting up and mundane tasks such as opening apps. iTunes takes a good minute to get up and going. I never even noticed the slowness until i got a MacBook with much worse specs that blew it away. So I decided to run TechTool Deluxe and see what happened. My iMac did great until the Volume Structure. I repaired it a good five times. The last two times it couldn't find anything to fix and it is still failing! I don't want to have to buy DiscWarrior (i think thats right), or reformat my drive, mainly because i haven't the foggiest on how to do that. Any options available to me besides these? And do you think the slowness is more due to a growing amount of files, or maybe even a *virus* *gasp*, or to the failing structure?
