I have a second hard drive with DOS and WIN 3.11 installed already that I can use, so I know it's compatible with this vintage PC. I want to overwrite everything with an exact bit for bit copy of the original hard drive.
I need to run a lot of external hardware with all of the drivers and software that is installed on the original hard drive. This is an automated test PC that is running motor control profiles and acquiring data with Metra Byte data acquisition cards. The code is written in C.
