Our History
Kroll Ontrack's roots were planted in 1985 with the development of Disk Manager®, a software program that makes the process of installing a computer hard disk much easier. Disk Manager remains a top-selling software product, and, to date, more than 150-million copies of Disk Manager have sold worldwide.
The success of Disk Manager led the company into the business of recovering data from damaged hard disk drives, resulting in the formation of ONTRACK Data Recovery in 1987. ONTRACK Data Recovery pioneered the tools and techniques for the data recovery industry.
As the demand for data recovery services grew, the company evolved in size, product and service offerings and expertise.
