how make a write protected pendrive?

Dear all
         I need to make a write protected pendrive to protect my pendrive from viruses. after the protection it should be readable in dos mode without any password, but no body can write or edit files on the pendrive.

Thanks

The easiest way is to use a small memory card to USB adapter (probably SD or MemoryStick), then buy the memory card to go with it. Just write protect the card when you are ready, and you can turn off the write protection when you are ready.

That is what CD's do. So just use CD or DVD discs

I think I would buy one - they do exist with write protection on them.

In 23 years of using the internet I have encountered viruses a tiny handful of times. Virus protection goes without saying so perhaps you should review what your looking at on the web to avoid areas where viruses profligate.
