I repair a lot of computers with viruses, malware, and what not, and I have one problem that I am struggling to find a solution for. Whenever I connect my USB stick that has the tools I need for the repair process it gets infected and especially the exe files, so after the repair is done i have to scan the USB stick.
My main problem is that sometimes the infections at my USB stick are so bad that I can't disinfect the exe files and I have to copy them all over again. It is very inconvenient since I have around 8GB of programs on it, and copying it all over again is consuming & wears out my USB stick.
I need a solution that would prevent the infected computer from writing to my USB stick in any way. I have had one program that I have had run before I connect the USB to the infected computer and the program would fill the USB stick with empty file so that there isn't any space left to write anything, but that solution isn't good for me since it wears out the stick very fast (it is a Patriot Extreme which isn't the cheapest at the market).
So if you know about a way to protect the USB stick from being written while it is connected to the infected computer, please give me your advice.
I prefer to use my current USB stick, I know about the hardware slide that some USB sticks and SD cards come with, but I prefer my USB.
