Is it possible to buy RAW SD cards? I mean without a master boot record or partition table. I have been using WinHex to write zeros to all the memory addresses thereby wiping out the partition tables, but this is time consuming. Can I just buy them “blank”? Does anyone have a source?

    You don’t need a raw SD card, you can do what you need to do within Windows:

    • Attach the SD card to the system/put it into the SD card reader
    • Open up Command Prompt
    • Type in: Diskpart
    • Type in: List Disk
    • Locate the number corresponding to the disk
    • Where X is the number you found, type in: Select Disk X
    • Type in: Clean

    That’s it! Now, be very, VERY careful. If you put in the wrong number, YOU WILL PERMANENTLY WIPE THE CONTENTS OF THE DRIVE YOU SELECTED. It’s on you, if you make a mistake.

    “Exit” exits out of Diskpart. I don’t remember if you have to exit out of diskpart and reenter for it to see a change when you remove and insert a new SD card.

    I’m sure there’s other ways to do this, but this is built into Windows, at zero cost.
