Rescue Usb Vs Rescue Cd

Hi folks!

What is the advantage of using Rescue usb over rescue CD?

While I create Rescue usb, I used the recommended on the site program, and I select option:

"preserve files across reboots", but the option not works in during using USB flash

I'm not sure but it should work with unetbootin.It's a tool specialy designed to make bootable usb from iso

images.I used it and it worked on my kingston usb.

In my opinion the old CD is better because viruses can't copy so easy on it.When you plug the usb in the infected pc the stick can be infected.

Surf the web for the unetbootin.It's free.

If you already use it allocate a few megabytes to preserve files accross reboots.2-5 should be enough.
