east-tec DisposeSecure vs ShredOS

east-tec DisposeSecure erases hard drives, selected partitions and connected external drives before computers are resold, donated or retired. The maker says its wiping methods meet and exceed the U.S. Department of Defense 5220.22-M disk-sanitizing standard, as well as other military, government and industrial standards. It can start from USB, CD, DVD, floppy or a local network, so erasure can run independently of the computer’s operating system. A Windows module handles detected non-system drives and partitions, including USB drives, memory cards and optical media. Over a local network, it can wipe multiple computers and send reports to a server; reports can also be saved locally for auditing or recordkeeping. The DisposeSecure Plan covers up to 10 PCs and includes one year of free updates and support. A fully functional 15-day trial is offered at no cost or obligation. Listed plan prices are $29.50 a month and $29.50 a year. For bootable disk use, the download page lists support for hard drives up to 1 TB.

ShredOS is a small, bootable operating system for erasing disks with nwipe. The project provides .img and .iso images for USB drives, CD/DVD, Ventoy, and virtual machines. It supports x86 PCs and servers, plus Intel-based Macs, with BIOS or UEFI booting. Nwipe offers several erasure methods and pseudo-random generators, configurable rounds, verification, and a final blanking pass. ShredOS can create PDF erasure certificates and log files, with reports focused on a selected drive or the system. The image also contains utilities including smartmontools, hdparm, nvme-cli, sg3_utils, hexedit, and parallel. Documented workflows include unattended autonuke, PXE booting, persistent configuration, custom scripts, and headless operation. A user-enabled Telnet server is available in documented setups for systems with faulty or missing display hardware. Logs and PDFs can be sent to FTP or TFTP servers, though FTP does not encrypt data. The project warns that wiping is irreversible and that writing an image to a USB flash drive overwrites its existing contents. ShredOS is free and open source, with 32-bit and 64-bit builds.
