I really have no idea what the problem is. =\ I've been looking into forums and help files all afternoon and have tried a few things, but nothing seems to stick. I've got a MacBook Pro running OS X 10.4.8, 2 GHz, 100GB HD, 1 gig of RAM. First inkling that anything was wrong happened when I was preparing to download the latest version of iTunes-- I was attempting to back-up my library to a DVD and iTunes couldn't recognize the disc burner or software. Tried a few times and always the same thing, so I thought I'd run the Disk Utility. It wouldn't open-- kept crashing immediately. So I ran TechTool Deluxe that came with my AppleCare package and it reported everything okay. Next, I booted up off of the OS X disc and ran Disk Utility off of it. It spat back, immediately after "Checking Catalog File" the following: It also spat back numerous permission errors, so I tried repairing those to see if it changed anything. Those repairs were successful, but the Error on the other one remained unchanged. So, I poked around some more here and tried running the fsck command. Sent the command three times and all times it spit back the same error message: "Invalid record count (4, 284)". So I've hit a wall. I don't know what the problem, what I should do, what I can do. Aside from the Disk Utility crashing and iTunes not being able to back up my files, I'm not aware of any problems, per se, with the laptop, but I'd like to take care of this before it becomes more serious. Any suggestions would be greatly appreciated. Thanks. -emtrey *edit* Oh, almost forgot. The crash log for Disk Utility says something about Library not loaded, reason: image not found. Not sure if that's relevant, but thought I'd mention it.
