The worst is that Altair might be physically incapable of handling the the large card (hardware incompatibility).

I think this is what we're looking at. When I try to access the card through Windows Explorer, I get a message that says the drive cannot be accessed because of an I/O device error.

When I try Disk Manager, it just freezes up, as if the sight of the shadow in the doorway is enough to unman it.
