Cheers, Chuck --------------------- Billy wrote: HP rolled out the Kittyhawk in the mid-'80s. It had reasonable success in some printers and copiers, as well as a few other applications. They are fun little drives to play with. The Cricket was about 8 years earlier and had no success - the technology wasn't there. There were many other experiments in small factor over the last 30 years. I remember a Comdex in the late '80s where IBM showed off a 7/8" drive. They were going to mount 32 of them on both sides of PC card and have a plug in RAID system. Like all multiple drive applications, the vibration from drive working gave errors to the rest. Conner made a 1.3 inch drive in the early '90s. I see them on eBay a few times a year. I have one that is still operational. There have been numerous attempts at the small form factor. The iPod was the first practical application so it drove the 1.8" development and production. It also drove the 1" development. That turned out to be a disaster for everyone involved when the Price War on NAND Flash destroyed the 1" market. It didn't help the Flash people either. (So far this year, NAND prices have dropped 65%!) There must have been other small drives. It's an idea that looks great until you try to do execute. I've only mentioned the ones that I worked on or have samples to study. Billy
