    Format zeros a drive?

    I've read from MSFT that from Vista onwards the full format command actually zeros the drive...

    Anyone actually tested this? Seems easier than setting a PC aside for Boot'n'Nuke.

    Just run a full format with Windows 8.1 on the SD card that is being given away in the classifieds and no recovery tools have been able to crack it.

    "Quick format" definitely does not zero a disk and all the data remains. Full format might but if I want to recycle a disk I use a military-grade multi-pass tool. Single pass just doesn't do a good enough job on personal data.
    Sensitive data should always be be encrypted anyway in which case it renders wiping unnecessary.
    However if speed is important, a 12mm drill will go right through the platters and circuit board in less than 20 seconds

    No, one must account for software and hardware cache flushing, write completion, indirect connections such as USB and virtualisation drivers.
    Assuming that sending a format command to a NAS or SAN, which both have their own independant RAID Operating Systems, just once will do is foolhardy in the extreme.

    Secure disposal contractors actually literally shred disks through a mincer to save all the effort.
