Oh, this is bad... So, I woke up this morning and went to my computer, to find it hung up. I could move windows around, but that was it. I was not able to open any folders or applications. So, I restarted the computer. It took forever to boot up, and then I was presented with the Most Feared and Dreaded Blinking Folder/Question Mark Panic. I know what this means - the computer can't find a valid OS X install. I rebooted, reset the PRAM, no go. I then booted up from the OS X install DVD. I launched the Disk Utility to see if I could repair the hard drive, but it wasn't in the list! I could still see my second hard drive and my USB backup drive, but not the main drive. Panic++ So, fellow Mac Addicts, what's the next step? How can I tell if the drive is Really and Truly Hosed, rather than some stupid little thing like a boot record that needs to be rebuilt? Would it help to swap positions with my secondary drive? It just seems odd to me that it was running perfectly for years, and it died with no warning. I've got it shut down (usually it just sleeps while I'm at work) so maybe having time to cool off will help. Oh, and here are some details on my computer: PowerMac G5 1.8GHz DP 4GB RAM 1 TB Seagate Barracuda main drive (the one that's "dead") 120GB secondary drive (forget the brand) OS X 10.5.x (whatever the latest version that'll run on a non-intel mac) Wow, the timing on this is really bad. I'm prepping three Instructables (one due in three days!) and now I don't have access to my computer! Argh!
