claymoreshredder

Claymore-Shredder is an effective hard-disk, flash drive, media card, SSD, and single file shredder software program for your Mac.

The app securely deletes and shreds complete volumes and hard drives, USB flash drives, pen drives, media cards, SD, MMC, SSD, and other volumes. In contrast to conventional other shredder software products, which use a simple binary overwrite technique, Claymore-Shredder uses a 102-Bytes random string technology.
