Write protecting USB drive
Recently when I used my usb drive on another computer the files on my usb drive got infected by worms.
Is there any way to make an usb drive inherently write-protected like floppy disks with any software so that worms won't be able to infect it.
I searched for this but all solutions depend on tinkering with target computer(infected PC) registry. Utilities like thumbscrew also seem to give a similar solution.
Is there some kind of utility which would make the usb drive write-protected at my PC and does not involve tinkering with target computer's registry.
Does anyone know of any such utility or is it even possible to do this?
I heard some usb drives have write-protection toggle like those in floppy disks but mine doesn't have this.
