Without physical access to the machine so you can see (and control) what is
actually going on, there is no way to 100% guarantee that the data is
completely destroyed.

Many things could theoretically cause the process to end before completion,
including someone on the other end simply disconnecting the power.

If it absolutely has to be destroyed, then the only completely reliable way is
to physically take control of the machine and carry on from there.
