Disk Purge is a utility that erases all data from a hard disk drive, ensuring that information is truly removed and unrecoverable. It works with any PC operating system and provides three different security levels for sanitizing hard drives.
Disk Purge is a bootable CD utility that securely erases data from hard drives, USB flash drives, RAID arrays and other storage devices. It supports multiple interfaces (USB, SCSI, FireWire, ATA, SATA) and complies with the Department of Defense 5220‑22 data‑sanitization procedure.
The manual guides users through changing the BIOS boot order, selecting a disk, choosing a security level (Fast, DOD 5220‑22‑M, Extreme), and running the purge. It also includes troubleshooting tips for boot problems and error handling during the erase process.
| Supported drive interfaces | USB, SCSI, FIREWIRE, ATA, SATA |
|---|---|
| Supports USB flash drives | Yes |
| Supports RAID arrays | Yes |
| System requirement – CPU | Pentium class microprocessor or better |
| System requirement – RAM | 32 MB |
| Required CD drive | CD ROM Drive |
| Required video card | VGA video card |
Insert the CD disc into the CD ROM drive and restart your computer; if it does not boot automatically, change the boot sequence in the BIOS.
Three levels are offered: Fast (1 pass), DOD 5220‑22‑M (3 passes with verification), and Extreme (7 passes with verification).
Errors indicate bad blocks that could not be overwritten; the data on those blocks is unrecoverable, but the entire disk cannot be fully sanitized.
