Then worked on all the disk drives that CDC made over the years, but specialized on the floppies and cartridge drives. During this time, I kept a chart above my desk of all the companies that made or tried to make disk drives as a reminder of how fragile the market was. Some that came and went include Apple, TI, HP, Siemens, Nixdorf (before it merged with Siemens), DEC, Century, NCR, Burroughs, ISS, Unisys, Priam and so on. The last time I updated the list, it broke 100 names. Now there are only Hitachi, Seagate, WD, Toshiba and Fujitsu. There are a few more, but they don't register on the statistics - for example, Cornice and Magicstor. A goodly portion of my career has been spent on disk drives. I've worked for many of the companies that are frequently slammed or praised on this list. So I try to stay out of the religious arguments of who made crap, who made good drives. I have old drives that lasted 20 years and decorative bricks that didn't go for 2 days. And today, I still am still surrounded with drives: right now I'm working on 1" drives for MP3 players. And buying cell phones to move to the next generation of interfaces and form factors. My first disk drive had 1 mega-characters (6 bits instead of bytes). Now 1 terabyte drives are coming near term. So it's very hard to pick any favorites or villains. The one constant in all this technology change is: there is a very good living to be made repairing computers and electronics. Billy
