Copy My Passport Wireless to External Drive?

[websiteauthor]

Is there a way to plug an external hard drive into the MPW and copy the contents of the MPW to the external hard drive without a computer?

I’m obsessive about backups when I’m on an extended vacation LOL - before I clear the cards I want to have them backed up to two drives.

it is not possible doing that way as I know.
