Disk Manager

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 that is now part of KLDiscovery.

Installation covered different aspects: Drivers could be either DOS-type, or replacement master boot record code.

Not long after launching in 1985, Ontrack also started providing computer disk data recovery services as Ontrack Data Recovery.

Other products that, like Disk Manager from OnTrack Computer Systems, perform hard drive geometry translation to circumvent BIOS limitations:[2]
