What Disk Shredder 7 is
Disk Shredder 7 erases disks in computers being recycled, discarded, or returned after rental or lease. It overwrites HDDs and can use disk secure-erase commands for SSDs; supported media also include external HDDs and SSDs and eMMC. The program starts from a supplied USB flash drive or DVD-ROM and does not require Windows installation. The maker says its method is recommended by NIST and refers to NIST SP 800-88 Rev. 1 erasure levels. Listed computers include Windows PCs and tablets and Intel Macs. Supported disks include SATA/IDE HDDs, SATA/NVMe SSDs, eMMC, and USB-connected drives. Erasure records can be saved to separate removable media and may include the date and time, method, computer details, and disk serial number. A copy can be reused on unlimited units but handles one computer at a time; five-packs allow up to five computers simultaneously. Plans are one-time purchases from 18,000 JPY to 342,000 JPY, with tax and delivery charges excluded. Lite plans fix the erasure method to one random-number pass unless qualifying customization is ordered.
