I am doing a clearout of some quite old computer gear and am removing
the hard drives before chucking it out. Most of the hard drives have
had many hours of operation and/or are of low capacity so are not worth
Therefore the intention is to sanitise them of data before they get
chucked as well.
To that end, I have looked at erasure software such Darik's Boot and
Nuke (DBAN), which seems to be a defacto for this job.
Unfortunately, and unsurprisingly, it seems to require potentially many
hours to do the job - perhaps 10 hrs per drive. It appears that
although it will handle all the drives visible (so 4 IDE on a standard
PC), it does them sequentially, so very protracted, and I have some 30
drives to do.
Therefore physical means seems to appeal.
There is the obvious one of bashing some 100mm nails through the case,
but I rather like the idea of fire - I have always been attracted by
any excuse for some pyrotechnics.
Thermite would appeal, but I can't be bothered to organise the
ingredients and environment to do it, so a blowtorch seems like a good
I found this video, where the guy does the job using a Mapp gas torch
and it seems to be an effective solution.
He mentions that it's hotter and faster than propane. I already
have a propane torch and cylinder so would need to go and buy a Mapp
gas handheld one - they seem not to be that expensive.
Has anybody done a disk destruction exercise, and more to the point has
anyone used Mapp gas? Is it significantly hotter than propane? What
other applications would it have?
