Drive eRazer wipes hard disks clean of data by overwriting every bit on the platters, carefully. The result is a drive that’s still usable but clean clean clean. No computer needed. For ultra peace of mind the Pro version overwrites multiple times. Comes with adapters for 3.5 or 2.5 inch drives and it’ll wipe a 250 GB drive in around 2 hours. From $99.95.
Does it meet DoD specifications? The Department of Defence has recently (June 28, 2007) updated their specifications regarding sanitization. Drive eRazer meets the DoD requirements for “clearing” a “Non-Removable Rigid Disk.” The specification requires destruction of a hard drive containing government classified data. As far as the DoD is concerned, Drive eRazer is as good as it gets without a degaussing machine or other destructive methods.
