However, after removing the SED, plugging in to a computer will show an unknown 0MB sized disk, which you can't read at all via OS interface, but I can still read it just fine in sector edit via COM + USB.
It shows up fine in the Marvell USB/COM utility

The issue at hand is that I cannot start a data extraction task in sector edit as it is disabled/grayed out:

And it doesn't show up in the data extraction tool new task interface either:

How can I extract all data from this disk? The only way I can read it's data / where it shows up is in "Sector Edit".
