Tasword WP program for DOS runs fine, but disk commands fail

[pauly]

Tasword WP program for DOS runs fine, but disk commands fail with the attached vDos error. Could it be that TASWORD uses an unusual way to access harddisk that vDos does'nt recognise? Or is it something that I can resolve in the set up? PS its looking for the default C:

Even if Tasword uses unsupported (hardware) methods to access C:, that shouldn’t result in a vDos exception.
What version of vDos do you use? Eventually install the latest 2023.05.01.
