There are legitimate reasons for such tomfoolery. I used to write firmware for Imprimis. I would take my Wren 5's and plug and unplug them from the bus. Of course I'd also pick them up while running and drop them... I got to know the hardware pretty well, as in "tap that capacitor hard and the drive will generate a servo error." It was a real handy way to test my firmware under adverse conditions. At one time, I was writing a lot of firmware to ensure drive survivability under such conditions. -- | ben@epmooch.UUCP (Ben Mesander) | "Cash is more important than | | ben%servalan.UUCP@uokmax.ecn.uoknor.edu | your mother." - Al Shugart, | | !chinet!uokmax!servalan!epmooch!ben | CEO, Seagate Technologies |
