What Disk Shredder 7 is
Disk Shredder 7 erases computer disks to help prevent data leaks when machines are recycled, discarded, or returned after rental or lease. It starts from a supplied USB flash drive or DVD-ROM, so installation on Windows is not required. For HDDs it overwrites data; for SSDs it can use disk secure-erase commands. It also supports external HDDs and SSDs and eMMC. The maker says the erasure method is recommended by NIST and references NIST SP 800-88 Rev. 1 erasure levels. Listed computers include Windows PCs and tablets and Intel Macs. Supported disks include SATA or IDE HDDs, SATA or NVMe SSDs, eMMC, and USB-connected HDDs and SSDs. Servers, RAID and SCSI connections, Android and iOS tablets, and Macs with M1 are not supported. A copy can be reused on unlimited units, but processes one computer at a time; five-packs allow up to five simultaneous computers. Erasure records can be saved to separate removable media.
