Forgive me if this is a repost, I can't recall. Weeks ago, the HD in my iBook 600 quit. I managed to clone everything off, so I'm running from Firewire. Just a bit slow waking from sleep, and of course I can't take the iBook anywhere... Now, I'm going to have to replace this sometime. Sigh. I reformatted the original HD. Everything seemed fine. I tried re-installing Panther. It went most of the way through and failed. Tried again and again, it failed three times. So I unmounted it and gave up. I rebooted a couple of days ago, and the internal HD mounted fine. And I wondered why it will mount but I can't install Panther on it. So, it's overheating? Were there any recalls on these IBM drives or did I just get unlucky ? Mean Time Between Failures is supposed to be ... what ? I thought it was supposed to be 4 years? Is it less for notebook drives? I need a 2.5 inch, therefore 9.5 MM notebook HD. Can I get a testimonial on what brand HD to get? I already checked with PBparts.com. I can send it in and get it fixed for about $200 after shipping. I've got the torx bits, maybe I'll fix it myself. Jkirk
