    Does anyone know of someway I can protect my USB from being able to be written to?
    I"m an IT person and is always plugging in my USB everywhere and I got a virus once.
    Thanks

    There's plenty of SD cards that have a physical read only switch, you can plug that into a SD-to-USB adapter. There's probably USB's with the same feature out there if you look around.

    Disabling autorun would largely prevent this anyways though, right?

    I use simple NTFS permissions to deny writing to the root folder, where autorun is usually placed, works on every computer.

    Enable Disk Protections does NOT cary over from computer to computer>
    Tested in VM and other computers.

    That option (Security) is NOT available on Flash Media.

    Just don't do that :thumbd:

    Have multiple USB drives, and use each one in specific context aka security zone.

    For example, Mirimir's USB drive never goes in my true-name personal and work machines, and vice versa. And there are other compartments with their own USB drives.

    Using that approach for network isolation is also prudent.

    Yes. You´d have to enable read only in each computer, which is inconvenient and the UFD could be written to before it´s protected.

    It´s possible to combine the read only protection with encrypting, which is desirable anyway. Encrypt the UFD with BitLocker. When you insert it in another computer, it can´t be written to, since it is encrypted. Then enable read only from diskpart, and after doing that, unblock the UFD with the encryption key.

    I have several flash drives with a physical READ ONLY switch on them. With the switch thrown there are NO writes to the flash. Simple. Not saying a three letter agency couldn't break one open, just that malware has never touched one anywhere that I know of. Mine are Imation but there probably are others out there. Check ebay, amazon, newegg, etc....

    Figured it out! Changed the USB into a hard drive by flipping the "firmware switch". Set security > Read Only.
    Now I'm trying to figure out how to stop it being written to cross-platform.
