Thanks for the details.
I did not know what CNC meant. I found out.
Computer Numerical Control (CNC) machines are automated milling devices that make industrial components without direct human assistance. They use coded instructions that are sent to an internal computer, which allows factories to fabricate parts accurately and quickly. There are many different types of CNC machines, ranging from drills to plasma cutters, so they can be used to make a wide variety of parts. Though most are used industrially in manufacturing, there are also hobby versions of most of the machines that can be used in private homes.(Years ago I worked in Machine Automation software, but never go into CNC.)
Some things you need to know. This applies to older computers make before about 2006. After that year changes were made to the BIOS as dictated by Intel.
MS-DOS was created long before hard drive had gigabyte capacities. So MS-DOS could not make partition larger than 2 gigabytes and could not read anything above 32 gigabytes. Partitions are also called volumes. Up to four primary partitions are the limit. One of these could be make into an extended partition, allowing logical drives to be made.
All hard drives used on DOS and Windows were marked a s type MSDOS. Most windows users never think about this, it matters to UNIX people. A raw drive might not be usable until a utility marks it as a MSDOS type.
Early version of DOS can NOT read FAT32 partitions.
Also, DOS and Windows require a drive to have at least one primary partition set as the active partition.
Sometimes a old drive can be 'reactivated' by having the active partition , the boot partition, away for the first part of the disk. Sometimes the first part of the dis is badly worn and will cause failures. So you avoid using the fist 100 mega bytes of the disk. That often works. MSDOS had a scan disk utility that could mark bad sectors. or weak hard drives you had to do this once in awhile.
Do this machines have floppy drives? MS DOS has utilizes that can be used to initialize a hard drive by booting from a floppy with the utilizes.

There are many experts here on MS-DOS. So come back and ask questions anytime.
How far did you get with Acronis today?
