One of the hottest issues in data security is
HDD data protection. Till now, some people believe the best way to make HDD
data disappeared is using a hammer to destroy it. However, in most of cases, a hammer
can no more than damage the casing.
After reviewing a few successful cases of
data recovery, it is quite amazing to see how easily experts are able to
recover data, even if the hard drive is badly damaged. The most famous case is
that of a leading Japanese information and communication technology (ICT)
company, Fujitsu. Before being acquired by Toshiba, Fujitsu was able to recover
data from a drilled HDD.
Two circumstances now also influence HDD
data protection — awareness of environmental protection & the emergence of the
solid state hybrid drive. In short, the former contributes to HDD recycle and
reuse, and the latter compels us to search for more creative alternatives
rather than relying on the “Hi-Tech solution” of magnetizing hard drives.
Hammering the HDD does not equate “data
security”, and therefore is not able to guarantee data safety. Similarly with
the solid state hybrid drive, if users do not destroy the Nand-Flash inside thoroughly,
there is still opportunities for data recovery. Therefore, if you’d like to
choose a green & effective way to destroy all worthless and sensitive HDD
data, a hammer is not the way to go.
