Definition: Disk Manager

A driver first introduced in 1985 from Ontrack Data Recovery, a Kroll Ontrack subsidiary, Eden Prairie, Minnesota that allowed older DOS PCs with a 32MB disk limit to access larger drives. Since PCs made before 1994 may have had a system BIOS that did not support larger drives, the Disk Manager utility grew in popularity and was often bundled with new hard disks. Over 150 million copies of the software have been sold. In 2004, Disk Manager 5.0 was released for drives over 137GB in size.
