PrairieTek Corp, the originator of the 2.5 Winchester disk drive, seems to have been hit by the curse of the pioneer: the Longmont, Colorado company says that since it launched the first such drive in 1988, several major manufacturers have entered the business, significantly increasing competition. As a result it is having to slash its workforce in Colorado by 210 people, 65% of the 325 total in the US. The lay-offs affect primarily production and administrative employees. The company says that it is now pursuing several activities to help it meet the current market situation.
