Hard Drive charts Gates's missteps as well as his successes: the failure of OS/2 and the embarrassing delays in bringing Windows to the marketplace; the highly publicized split with IBM, which then forged an alliance with Apple to battle Microsoft; the public relations fallout over various exploits of Gates; and the investigations by the Federal Trade Commission. Wallace and Erickson also examine the combative, often abrasive side of Gates's personality that has alienated many of Microsoft's rivals and even employees, and led to his being labeled "The Silicon Bully" by Business Month Magazine. They report: In the early 80's, Microsoft's Multiplan lost out to Lotus 1-2-3 in the marketplace. According to one Microsoft programmer, a few of the key people working on DOS 2.0 had a saying at the time that "DOS isn't done until Lotus won't run." They managed to code a few hidden bugs into DOS 2.0 that caused Lotus 1-2-3 to breakdown when it was loaded. "There were as few as three or four people who knew this was being done," the employee said. He felt the highly competitive Gates was the ringleader.
