Hi there! A little over a year ago, my poor aluminum 15" PowerBook G4 died. I was reading a webpage, the color wheel came up and wouldn't go away, I restarted the computer, and the dreaded Happy Mac/question mark flashed on my screen accompanied by a knocking sound coming from the hard drive. By some miracle of technology, I was able to get the PowerBook to boot up by placing it on its side (which caused the knocking to cease), but it kept running slower and slower as I frantically tried to transfer my files to my external hard drive, and eventually I had to power it down. It hasn't successfully booted up since. I replaced it with the MacBook I'm currently typing on, but I really miss my PowerBook, and lately I've been playing around with the idea of installing a new hard drive, something that I've never done before. Following the instructions on ifixit.com, I removed the old hard drive, and now I'm wondering if there's any way to recover the data (short of paying out the nose for a data recovery service; while there are some things I'd really like to get back, I managed to save most of my photos and other important files). I've given the drive up as lost with the possibility of recovering any files viewed as nothing but a wonderful bonus, so I'm open to trying pretty much anything. For instance, I'm currently giving the ol' "freeze the hard drive" trick a shot. I bagged the drive today and shoved it in the freezer for about four hours, but, even though that initially decreased the knocking sound when I hooked the drive back up to the PowerBook, I'm still getting the blinking Happy Mac/question mark folder o' death upon startup. I've tried booting from the PowerBook install CD, but it doesn't even recognize the hard drive (nor does the drive show up if I hold down "option" while powering up, for that matter), so there's no way to try repairing it. I'm also thinking of getting a FireWire cable (if they're cheap; I haven't looked yet at what I'd need), booting up the PowerBook in Target Disk Mode, and hooking up my PowerBook to my MacBook in the hopes that it can see the hard drive. I guess what I'm asking is... what else can I do? If the PowerBook doesn't recognize the hard drive even when the hard drive isn't making that cringe-inducing knocking sound, does that mean it's toast? I don't know very much about computers and I'd really appreciate any advice. Lastly, once I save up a little cash, would this be a good replacement hard drive for my PowerBook? I don't need a lot of space, and this is about as cheap as I could find. Since we're a little strapped for cash right now, I don't want to spend a lot of money on a hard drive, especially if there's a possibility that there's something wrong with the PowerBook itself that's caused the original hard drive to fry. Thanks in advance for your help and your time!
