Hello all This is my first post on MR (long time reader) because, cocky as it may sound, this is the first problem I have had with my Mac that i haven't been able to fix (with help from forums and such, of course). After searching around on the forums, both here and Apple's discussion threads, I have yet to find a solution. I apologize if a solution to my problem has already been posted and I just haven't looked hard enough, in which case please direct me to it and i will promptly delete this thread. But without further ado, here is a copy of my post on Apple's discussion threads (cuz I'm lazy): To which I added: And now, literally as I was just typing, I swear, Time Machine threw another error at me as I was trying once again: "The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk." Too late to worry about that now! but yeah, as in the post, I'd greatly appreciate any help. Cuz I'm really confused please bear with me as i'm still learning the ropes here.
