Hey everyone, I've been a long-time lurker here (going on three years now), but I've finally got a couple questions that need to be answered. My 1.33ghz 12" PB started acting up today for the first time since I bought it almost two and half years ago. iTunes began to stutter, along with numerous multi-colour beachballs that wouldn't go away until I force a reboot. The symptoms came back again after a while of playing iTunes with MSN running in the background. I reboot again, this time in verbose mode, when I got an "ioatacontroller device blocking bus" message several times in a row. This time booting took a great deal more time, until I tilted my PB to one side. Once it was up, I did a quick google of the messages and found several similar situations, like this <a href="http://dubinko.info/blog/2004/07.html">one</a> mid-way down the page, all leading to a dying/dead hard drive. Fearing the worst, I backed up all of my data to my iPod, which seemed to speed up whenever I tilted the PB onto one side. I booted my 10.4 install disk and repaired the hard drive, which came up with a "header needs minor repair" error, which seems to be fixed now. The S.M.A.R.T. status is still reading as verified. I've rebooted and it seems to be running fine now, so long story short, am I being paranoid or is my hard drive slowly dying? Also, if it is a worst case scenario, what would be a good choice for a replacement hd?
