Software to erase the data stored on a hard disk. Supports multiple drives and wipes them all simultaneously. Wiped the entire drive, not only what windows sees. Supports ATA/SATA/SCSI/SAS/USB/FIREWIRE and memory cards attached through USB. Can also be used for secure deletion of hard disks prior to disposal. Overwriting can be a single charater or can be a text string set by the user. For example, or There are some problems with secure wiping software in that hard disks use SMART for bad sector manipulation. When a bad sector is encountered by SMART it replaces the sector with a new one from the spare sector pool. The problem is that the data that was stored in the bad sector is still on the hard disk and can not be accessed by the user. Specialist data recovery companies can often regain access to this data. In most cases it is not a problem, however if the bad sectors were to contain confidential information, then there is a small risk that it can be accessed by people with access to specialist data recovery equipment.
