Zac67 gave you the link to check the settings for the HDToolbox. The TOOL can be customised to scan for certain drives and or devices. The tool is probably the default for the Workbench, but not necessarily the one that set up the hard drive. So if you check the HD Toolbox as suggested you can see what the tool is scanning for and or recognising. Don't forget that the Toolbox is just a TOOL.
Also find out what the card is... ie a GVP and that could help you link to say The Big Book of Hardware or the German equiv and get more information on the card and its jumpers etc and limitations. Personally if you can work with what you have on the card I wouldn't mess with it.
