Could not determine the size of the actually used data area.

Device size would be truncated, which
would corrupt data and result in
'access beyond end of device' errors.
If you want me to do this, you need to zero out the first part
of the device (destroy the content).
You should be very sure that you mean it.
Operation refused.
