Sorry, this just tickled me. "gear train" ? Which decade are we talking about? The last drive I saw that had any form of mechanical power transfer mechanism for head positioning was a 60MB RLL Seagate clunker. Now, to add some form of use to the thread I've been using commodity CF cards in home-brew CF to ATA adaptors in embedded systems for 10 years. Flash is _the_ way to go for high reliability systems that don't have lots of write cycles. My TV box that has no on-board PXE has been booting from a 10MB USB stick using loadlinux since 2003. Dead reliable after ~69,000 hours power on time. I've not had a hard disk last that long since my old 200MB WD IDE drive (which is still running with over 100,000 hours on it).
