We used to use a "Degaußer" for hard disks. Recently, a colleague put the
degaußed disk back into his PC and could read data without problems. So, either
the Degaußer is broken or for whatever reasons it did not work. And this is a
problem if you rely on something you can not verify immediately. For example if
I use a big hammer I immedialtey see the results. But a degaußed Disk does not
looked destroyed - you can not verify it with your eyes.
So, we do not rely on degaußing anymore without verifiying (reconnect and
test). So we prefer the hammer or commercial services (which still can fail,
but then you can sue someone)
