Abstract

One of the common anecdotal complaints used when defending the insecure erasure of hard disks is the length of time taken to affect a secure erasure. This paper discusses results of experiments conducted with Unix/Linux based hard disk wiping software when run on various machines and hard disk mechanisms in terms of size, speed and interface. The initial research has uncovered a range of issues and factors that affect the speed of erasure of hard disk mechanisms. Some of these factors included memory configuration and CPU but not in ways that were expected. This paper includes results from contemporary ATA and the newer SATA IDE hard disk drives in use today.
