My ol' 80GB hard drive is the last that remains of my original computer, built in Summer 2003. (All other components, including the case, have been upgraded.) Just a few minutes ago, when I tried booting my desktop up, it would spin up, click, repeat. Broked!!!
Fortunately it was a good sport after I released it from its mount and now it's letting me run Vista to back everything up (although I backed up last week, so all would be pretty good anyway). So it's working again, but I don't trust it with my data anymore. I just bought a 500GB 3GB/s SATA drive to replace it. It's been a great trip buddy! Best 80GB I ever owned!
