Last night when I went to bed my new (to me anyway) Powerbook G4 was working fine. This morning when I got up it was severely misbehaving - there was 9.5gb of RAM in use and nothing was responding. I started shutting everything down and at one point tried to turn off the local ColdFusion 8 server using sudo, only to have an error that my account wasn't in the sudoers list; given that my account was an administrator, this was not good. I left it to continue rebooting but when I got back, a half hour later, it had pretty much frozen up trying to load a few starter apps. This, along with the noise coming from the drive, told me what I already knew - the drive was dead.
