Hot to get rid of non-dos ghost drives on main window

[QuikSanz]

I have installed/partitioned some new drives during my 3.9 upgrade.
I also have a few residual "non-dos drives" that I cannot use due to size of new drive partitions. Is there anyway of getting rid of these drives on main screen...hiding them is fine for now.

Thanks

It's a left over .info file that has no home. use a shell to delete.

I cannot see these drives from a Shell. They only appear on my WB screen at boot-up and the only thing I can do (unsuccessfully) is to try and format them - which prompts me with "Non-DOS" error (the icons on my WB screen state them as "unreadable")  These are unused space areas from my format drive.

A dir search should show it as a .info file with no real file associated with it. If not something is really wrong here.

There must be a gap between partitions or some part of the drive not labeled yet, strange.
