How many passes does wipe do/Why only one pass wiping?
Wipe and Delete only overwrites once, with pseudo random data. I’m currently not planning to implement DoD 5220.22 (NISPOM) sanitization, nor Gutmann 35-pass secure-wipe. The cost of retrieving single-overwritten data is prohibitive as it is, if the attacker has the resources for that (as well as getting physical access to the disk) there are many easier and surer ways of getting at the data. A PC is such an insecure and uncontrolled environment, that to use DoD-style wiping in a running system is severe overkill and misleading. Such wiping should be used prior to destruction or re-use of hard disks, and then only from a stand-alone diskette and CD so that the entire disk surface may be wiped, regardless of operating system structures. I recommend Boot and Nuke for this purpose. The purpose of AxCrypt wiping is to protect from use of common un-delete tools, not to protect from electron microscopy or special diagnostic hardware and software available to hard disc manufacturers.
