I have a very old laptop (Dell Latitude L400) I use for retro-gaming in which I replaced the the hard drive with a CF Card Adapter and I use several 16 GB cards with it, swapping them as needed.
Since the BIOS doesn't recognize the cards at their full capacity (it sees them as 400 MB drives) I had to use Ontrack Disk Manager (version 9.4) to setup those cards, So far everything seems to be ok, I was able to install DOS and Windows 98 on them and they see these cards at full capacity.
The problem is that sometimes I would like to be able to use these cards with my main Windows 10 machine to transfer files faster than using the network, usb drives or burning cd's. Since Ontrack uses a custom partitioning scheme (it installs itself at the beginning of the drive and shifts the partition table to make room) I can't use these cards with neither Windows 10 or Linux (Ubuntu 18.04).
So Is there any tool that would allow me to either mount the drives or be able to read/write data to them using a standard USB card reader? Any solution that would work on Windows, Linux or OSX would be perfect.
