Disk Manager is a discontinued software (that was a popular 1980s and 1990s) and documentation package for MS-DOS and PC DOS computers, useful for self-installing personal computer hard disks. It was written by Ontrack, a company later acquired by Kroll Inc.
Installation covered different aspects:
explaining personal computer hardware conceptsdocumenting switches of many of the existing disksputting into place custom device drivers which circumvented BIOS limitations, notably those related to maximum disk or partition size and logical block addressingproviding testing and informational utilities
Drivers could be either DOS-type, or replacement master boot record code.
Diskettes with Disk Manager were provided by some disk manufacturers (e.g. IBM), in custom OEM versions, supporting all of their models.
In recent years Kroll switched to the business of providing computer disk data recovery services as Kroll Ontrack Data Recovery.
