I read something somewhere that if your hard drive starts to fail, put it in a cold environment. I can't remember where I saw this, but a guy put his laptop in the fridge to get his HD up and running long enough to pull the data from it.
Flash drives are somewhat touchy with their reliability. Apparently they're only good for a certain number of writes before they go kaput. That's why I have my OS and my music on seperate drives. The OS does more writes to the drive, but that may be debateable with the Linux OS since it runs in RAM and writes one backup file on shutdown. I'm mainly using a flash drive for reliability in Winter.
Oh yeah, and BUMP. My video has fallen behind the guy who thinks LAMP environments are cool.
