Ontrack Disk Manager 2000 4.06.05 // Ontrack Disk Manager For DOS/Windows 9.61.06

This is a version of the Ontrack Disk Manager released by IBM/Hitachi after they merged their mass storage divisions. Before 9.61 it was called "IBM Disk Manager" and was just the retail version of Ontrack Disk Manager with the IBM name stuck to it. That tradition continued with this version being named "Hitachi" but is otherwise identical to the full retail version of Ontrack Disk Manager 2000/Ontrack Disk Manager For DOS/Windows with no restrictions on what kind of drive you can use it on (I've personally used it on a CF-to-IDE adapter running a Lexar CF card to great success). It is essentially composed of two products, Ontrack Disk Manager 2000 for Windows 95/98/ME/NT/2000/XP, and Ontrack Disk Manager for DOS/Windows 3.x.

If you want to manage a disk drive for 95/98/ME/NT/2000/XP you'll want to use the diskmanagersetup.zip file from the link at the top. If you want to make a disk to use with DOS/Windows 3.x you'll want to download the DMDISK.zip file instead.

It officially supports:

Windows 95, Windows 98, Windows Me (*Ontrack Disk Manager 2000 4.06)

Windows XP Home and Windows XP Professional (*Ontrack Disk Manager 2000 4.06)

Windows 2000 Professional· Windows NT Workstation 4.0 (*Ontrack Disk Manager 2000 4.06)

Windows 3.x* - (*Ontrack Disk Manager For DOS/Windows 9.61)

DOS versions 3.31* and greater (*Ontrack Disk Manager For DOS/Windows 9.61)

This is the very last version of Ontrack Disk Manager that supports Windows 3.1x and DOS.

Even though the overall product for DOS/Windows 3.x is version 9.61.06 the Dynamic Disk Overlay (which is the portion that allows you to use larger disk drives on older systems and versions of the DOS/Windows OS) is a higher version, 9.83, which is the latest known version of the Ontrack Disk Manager - Dynamic Disk Overlay.

This version is capable of updating older versions of the Ontrack Disk Manager, such as 9.57, in place without harming the files on the disk you have the ODM-DDO installed.

The Ontrack Disk Manager 9.61 for DOS/Windows 3.x can only be accessed through the DMDISK "Diskette Creator" program which makes a boot diskette through which the Ontrack Disk Manager can be run for managing any drives that are have or are going to have DOS/Windows 3.x. This is only possible if you have a usable 1.44 MB HD 3.5" disk drive and a single blank disk to use with the program.

Below is a link in the Internet Archive page that contained the complete Hitachi - Ontrack Disk Manager 2000 v4.06.05 that they offered up for free on their website, proving that it is indeed Freeware:

These are the pages from Ontrack that describe what the software supports and what it can do:

I'm impressed they managed to make a product that supports DOS 3.31 with FAT16B through Windows XP with NTFS. With regard to DOS/Windows I found 9.61 to be noticeably faster with regard to booting the DDO and loading WFW 3.11.
