dataEx enables to securely delete any information (files or entire folders) on removable media (flash storage technology) and hard disks (magnetic storage) or to securely format entire media (including rewritable optical media).
- The operating systems own delete functions do not delete – they only unblock the reserved space for further use. Its left to chance, if and when the cleared space is really used. Anyway, the data on the storage medium remains readable for everyone, having access to the medium.
- In the case of USB sticks or other removable media the access is particularly easy. The user believes, the data is apparently deleted – but nevertheless trespassers may get hold of it, without anybody noticing or having done anything wrong.
- A PC storage medium is given to a service provider for maintenance or "repair" – that is for example warranty claims or the larification of technical problems. Confidential data has been deleted, but not securely deleted.
